The quality of a total solution is determi ned by the quality of its components. A fault in a component which only costs a few cents can paralyse everything. Per fection down to the smallest detail is the refore the basis of our philosophy as a supplier of mechatronic components. Another is attuning the individual ele ments optimally to one another. There fore, we see ourselves as our customers` active partner when it comes to develo ping new products.
Our record proves we are right. For many years, Cherry snap switches and key boards have been synonymous with the highest quality and reliability. This prin ciple has also made us one of the leading suppliers of electronic components. Re gardless of whether you use our products in household appliances, industrial appli cations, in the automobile industry or for input systems you can rely on safety and comfort in addition to reliable functionality.
Philosophy
6
Customer satisfaction grows with quality. And quality with proximity to the customer.
With evershorter product cycles, the development time for new products is also being reduced. In order to guarantee maximum quality neverthe less, close cooperation among all partners is important. We interpret the term ,,close cooperation" in an oldfashioned way and insofar wherever possible, we prefer personal contact with our partners.

To be as close to our customers as pos sible was the principle of Cherry Electrical Products Corporation, which was founded in the USA in 195. In 1964 we established a subsidiary in Germany and in 1972 in England. In the meantime, our locations in Europe include France and the Czech Republic, and they employ approximately 2.000 people. Proximity on location allows us to react quickly to regional or individual requirements.
This is a part of our recipe for quality, which enabled Cherry to generate reve nue of EUR 200 million in Europe in 2005. Further locations will also depend on you. With our flexible production network, we are in a position to react to customer and market requirements.

Snap Switches Definitions and descriptions
Snap switches, also called microswitches, are activated by a spring operated (or ,,snapaction") mechanism. Depressing the actuator trig gers the switching operation, with a predefined force and travel. The switching speed itself is largely independent of the speed of actuation.

Actuator
Applying force to the actuator of a snap switch releases the snapaction mecha nism, which in turn triggers the switching operation.

Single Pole Single Throw Normally Closed (Break contact) Function In rest position the COM terminal is con nected to the NC contact. When the actu ator is depressed, COM and NC break contact and COM and NO make contact. When the switch is actuated, contact is made. When the switch is actuated, contact is broken. Graphical
Auxiliary actuator
It is possible to attach an auxiliary actua tor to a snap switch in order to meet the specific requirements of a given applica tion. Doing so usually alters the travel and forces involved in the switching operation, depending on the length of the levers. By attaching an appropriate auxiliary actua tor, it is possible to increase travel and/or reduce the actuating force required.
Contact gap (contact opening distance)
The contact gap is the distance between a pair of open contacts. For snap swit ches, it is usually around 0. mm. Gene rally speaking, for switches with contact gaps < mm, additional measures are necessary for separation from the mains. These switches bear the mark µ for Euro pean approvals. Switches with a contact gap > mm can generally be used directly for separation from the mains. Please check the device specifications applying to your particular product, and if there is any doubt, please clarify with the respon sible testing agencies.
Clearance and creepage distance
Clearance is the shortest distance through the air between two electrically conductive parts or between an electrically conductive part and a metal foil affixed to an access ible surface of some insulating material. The creepage distance is the shortest dis tance along the surface of an isolating ma terial between two electrically conductive parts or between an electrically conductive part and a metal foil fixed to an accessible surface of the insulating material.
Terminals
COM (Common = 1): Base terminal NC (Normally Closed = 2): The contact is closed in the rest position, that is, the terminal is connected to COM. When the switch is actuated, the contact opens. NO (Normally Open = 4): The contact is open in the rest position, that is, the terminal is separated from COM. When the switch is actuated, the contact closes.

Positions, forces and travels
Actuator positions
Dimensions for actuator positions are al ways specified in relation to a given refe rence line. Rest position The rest position is the position of the ac tuator when no external force is being ap plied. Sometimes referred to as the "free position". Operating point (mech.) The point along the actuator's travel path at which the springoperated mechanism is actuated. Final position (total travelled position) The position of the actuator at the end of its travel. Reset point (mech.) The point along the actuator's path, as it travels back to its rest position, at which the springoperated mechanism snaps back to its original position.
Actuator travel
Pretravel The distance travelled between the actuator's rest position and the switching point. Overtravel The distance travelled between the swit ching point and the end position. To make absolutely sure that the switching opera tion takes place, an actuator should use up at least 50 % of the available overtra vel. Reset travel The distance travelled between the end position and the release point. Free travel (open circuit travel) The distance travelled between the reset point and the rest position. Total travel The sum of pretravel and overtravel, or of reset travel and free travel. Movement differential The distance travelled between the opera ting point and the reset point.
15
Forces
Initial force The force required to move the actuator away from its rest position. Operating force The force required to move the actuator through the operating point. Sustaining force The force required to hold the actuator in its final position. Reset force The level to which the operating force must be reduced to allow the springope rated mechanism to return to its original position. Differential force The difference between the operating force and the reset force.

Operating life, temperature resistance, vibration and electric resistance
Operating life
The operating life specifies the minimum number of switch cycles within the speci fic values. It depends on a large number of parameters that are determined by the intended application case. Among these are, for example: · switched current and switching voltage · type of load (e. g. ohmic, inductive or lamp load) · Combination of materials in actuating element/actuator · Actuator type · Actuator speed · Switching frequency (switching cycles / min) · Pretravel / Overtravel · Environmental factors such as climate conditions or harmful gases (e. g. SO2) Please note: Media such as greases, oils and materials which contain silicon must not be used on the switch. There is a distinction between mechanical and electrical operating life.
Mechanical life
Indicates how often a switch can be actu ated without an electrical load. Mechani cal endurance is calculated by actuating the snap switches axially in relation to the actuator in a sinusoidal pattern using about 80 % overtravel at a switching frequency of 4Hz at room temperature.
Electrical life
The selection of the optimal contact mate rial has great influence on the operating life. The electrical life test is conducted at rated voltage, rated current and resistive load at 2 °C ambient temperature. The lower the electrical current, the longer the electrical life under some circumstances it may even equal the switch's mechanical life.
Please note: For switching loads which deviate from the values specified in the catalogue, we recommend that you discuss the issues involved with Cherry. This is especially important if you are using other consumers as linear resistances. These can be electrical circuits with inductive resistances (motors), capacitive resistances (condensers) or lamp loads. To ensure that a switch reaches the end of its electrical operating life, the switch should not be subjected to pressure in its rest position (pre-stressed) and at least 50 % of the available overtravel must be used. Operating life specifications for direct current loads are available on request. Where higher switching capacities are involved, we recommend the use of fuses to provide protection against arcing. Please note: Since the operating life of a snap switch depends on a number of factors, we recommend that field trials be performed in order to establish the likely electrical life of a switch in a given application. This is especially recommended when the application deviates considerably from the test conditions described above. Our specialists are always ready to provide you with more advice regarding possible solutions for your particular application.
17
Behaviour at different temperatures
Depending on the model, the operating temperatures of our switches range from 25 to + 70 °C and 40 to + 150 °C. If you attempt to use a switch at operating tem peratures either above or below those re commended for your particular model, the switch`s material properties will change and its reliability will be affected. Where switch model codes start with "T" (e. g. 40T125 in compliance with EN 61058), the switches involved have been approved for use at the corresponding temperatures.
Vibration and shock resistance
Snap switches are naturally fairly resistant to shocks and vibrations thanks to their minimal mass of moving parts. They are at their most resistant when the actuator is in the rest position or end position, when vibration resistance is as high as 5 g at 20 200 Hz while shock resistance attains 20 g (6 ms). Please note: Snap switches are more susceptible to vibrations at the switching point and at the release point. In certain conditions, this could result in transient make or break contacts (bouncing) to the detriment of the switch`s operating life. This is why snap switches which are regularly exposed to vibration should, wherever possible, not be actuated slowly.
Electric strength
The electric strength of our snap switches is in the case of models suited for mains voltages exceeds 1500 VAC between con ducting parts and the earth and 750 VAC between the terminals (open contacts) measured over a period of one minute at an ambient temperature of 2 °C ± 5 °C, relative humidity of < 70 % and normal at mospheric pressure.

Operation, contact types and materials
Operating speed
Snap switches are suitable for a broad spectrum of operating speeds. However, extremely slow or fast actuations can affect the switch performance and operating life. For productspecific values, please see the technical specifications. The maximum switching frequency (swit chings / s) is limited by the electric load. With low switch loads, up to 10 actuations per second are possible. Please note: Sudden actuation must be avoided since it decreases the mechanical operating life.
Transit time
In twoway (doublethrow) switches, transit time is the time between the moment the break contact element (NC contact) first opens and the make contact element (NO contact) first closes. Transit time is gene rally determined by design features such as e. g. contact travel and elastic charac teristics. It generally varies between 5 and 10 ms, depending on the model. Please note: If transit time is critically important to the functioning of your application, don`t hesitate to contact us.
Contact materials
Gold and gold alloys: primarily AuAg; AuAgPt Silver and silver alloys: primarily Ag; AgNi; AgPd Gold alloys are especially suitable for low currents and voltages. Typically they are used in the range from 5 V 1 mA DC to , 12 V 100 mA DC. But it may also make sense to use them in switches which are only occasionally operated or in atmos pheres with a high sulphur content. For switching heavier loads, it usually makes sense to use silver or silver alloys. In this case, the range typically extends from 12 V, 100 mA DC to 250 V 21 mA AC. Please note: Because choosing the right contact materials depends on a large number of factors, such as switching voltage and current, operating environment, atmospheric conditions, etc., we are always pleased to advise you on the best choice of material for your application. Before making any firm decisions, we do advise you to carry out field trials of our switches in real-life conditions.
Contact bounce
Bounce time is the time between the mo ment closing contacts first touch and final (definitive) contact closure. The typical bounce time for our snap switches is around ms.
Contacts
We supply switches with standard and crosspoint contact technology. For low voltage and lowcurrent applications, we strongly recommend the use of gold cross point contacts. The reduced surface area of the crossshaped contacts means that the surface pressure is greater, which in turn enhances reliability. Standard contacts are more suitable for higher switched loads.
19
Materials and contact resistance
Materials
For our standard switches, we use high quality, cadmiumfree plastics which are optimised for the intended application. As a rule, we seek to avoid the use of toxic or hazardous materials. You can find out more about our materials policy by con sulting our hazardous substances exclu sion list. Behaviour of materials in fire Insulating materials which are directly connected to electrically conductive parts are classified according to their degree of flammability. Most of the materials we use to manufacture housings are selfextingui shing and categorised under the UL 94 V0 standard. Tracking resistance Most of the insulating materials we use in our snap switches have a proof tracking index of PTI 250 (PTI 00 on request). This means that they are capable of 50 drops of test fluid at a test voltage of 250 V without producing any leakage current (IEC 60112). RoHS Switches without leads already conform to RoHS. Switches with leads are available in RoHSconforming models on request. In case of further processing with lead free soldering, the productspecific solder recommendations must be heeded. (For more information, see page 20). Glow wire test The insulation materials used for snap switches with ENEC approval fulfil the required filament tests GWFI according to the household appliance standard IEC 6051 at 850 °C and GWIT at 775 °C or alternatively the filament test GWT at 750 °C.
Contact resistance
The contact resistance of snap switches is composed of the contact resistance and the resistance of the conductive parts. It depends primarily on the construction and the contact material. The contact resistance of silver contacts is max. 100 m , of gold contacts max. 50 m when they are new. Insulation resistance The insulation resistance between the con ductive parts of our snap switches and a conductive underlay or between the open contacts exceeds 10 M when they are new, measured over a period of one mi nute at room temperature with 500 V DC. Caution: humidity and soiling can decrease the insulation resistance.

RoHS
RoHS (Restriction of the Use of Certain Hazardous Substances) designates the guideline 2002 / 95 / EG of the European Parliament and Council. This forbids the use of particular substances in electrical and electronic devices, which are brought to the common market starting in July 2006.
Switches as supplied by Cherry are not themselves subject to the guidelines, but they are suitable for use in devices of the categories mentioned above. Cherry, as a leading manufacturer, feels obligated to ensure that its customers have transpa rency for the greatest possible security in decisionmaking. Overview of the Cherry switches with respect to conformance with the RoHS regulation.
Note
Explanations: not contained 1) According to the exception granted by the EU Commission (published in the EU Journal L280/18 v. 25/10/05), the use of cadmium and cadmium compounds in electrical contacts is still permissible. 2) Processing after consultation with Cherry.

Assembly and installation
Please note: Cherry snap switches should only be installed by trained staff. Generally, adherence to the required air gap and creepage distance must be ensured with suitable measures. These must also be adhered to for lines connected to the switch. If installation is to occur on a conductive surface, insulating panels must be used. Under some circumstances, their use is also required between switches installed alongside one another and plugin con nections. Switches can be installed in any position. Power transmission to the con nections of the switch is not permitted. When fastening with screws, screws with a coplanar contact surface must be used. (e. g. in accordance with DIN 84, DIN 912). Smooth, solid surfaces are suitable for in stallation. Exceeding of the following tigh tening torque values is not permissible. We recommend trial installations. If you wish to install your switches using coupling pins, we would be happy to advise you on suitable parameters. Please note: If components are likely to be subjected to vibrations, we advise you to take additional measures to secure them. With solder connections, the product-specific solder recommendations must be heeded in order to prevent damage or destruction of the switches. Please note: Cleaning agents and solvents in proximity to the switches can impair their function, especially in case of watertight models. When using greases (especially mineral oil-based ones), we recommend consultation with Cherry. The switching action may be initiated by a force acting vertically on the actuator, or by an angled actuation lever. Example:
max. 30°
Please note: The actuator may not be pre-stressed when at rest. When actuated, the switch should travel well beyond the switching point. for at least 50 % of the predefined overtravel, in order to ensure that full contact is made. It is quite unacceptable for the switch to exceed the specified overtravel or end position. Using the switch as a mechanical end stop should be avoided. A high-impact actuation of the switch can have a negative effect on the switch`s mechanical life.

The angle of the lever in relation to the top of the switch housing should not ex ceed 0 °. The precise angle will also de pend on the actuating speed, combination of materials, surface characteristics and so on. In case of auxiliary actuators with rollers or simulated rollers, steps should be taken to ensure that the lever does not impede its own action. This means that the direction of actuation should be away from the actuator`s mounting point towards the roller, and the angle of actuation should be adjusted to allow for the geometry of the actuation system. We would always recommend a preliminary discussion with Cherry.

It`s not the size which determines the power, but rather each individual component.
What makes the difference between a good and an excellent technical solution? Reliability, the power of innovation, with such a head start anyone can name the result. But how can this be achieved? Is there a formula which can be transferred to all industries? We think there is.
5
The quality of a total solution is determi ned by the quality of its components. A fault in a component which only costs a few cents can paralyse everything. Per fection down to the smallest detail is the refore the basis of our philosophy as a supplier of mechatronic components. Another is attuning the individual ele ments optimally to one another. There fore, we see ourselves as our customers` active partner when it comes to develo ping new products.
Our record proves we are right. For many years, Cherry snap switches and key boards have been synonymous with the highest quality and reliability. This prin ciple has also made us one of the leading suppliers of electronic components. Re gardless of whether you use our products in household appliances, industrial appli cations, in the automobile industry or for input systems you can rely on safety and comfort in addition to reliable functionality.
Philosophy
6
Customer satisfaction grows with quality. And quality with proximity to the customer.
With evershorter product cycles, the development time for new products is also being reduced. In order to guarantee maximum quality neverthe less, close cooperation among all partners is important. We interpret the term ,,close cooperation" in an oldfashioned way and insofar wherever possible, we prefer personal contact with our partners.
7
To be as close to our customers as pos sible was the principle of Cherry Electrical Products Corporation, which was founded in the USA in 195. In 1964 we established a subsidiary in Germany and in 1972 in England. In the meantime, our locations in Europe include France and the Czech Republic, and they employ approximately 2.000 people. Proximity on location allows us to react quickly to regional or individual requirements.
This is a part of our recipe for quality, which enabled Cherry to generate reve nue of EUR 200 million in Europe in 2005. Further locations will also depend on you. With our flexible production network, we are in a position to react to customer and market requirements.
Location and quality

Snap Switches Definitions and descriptions
Snap switches, also called microswitches, are activated by a spring operated (or ,,snapaction") mechanism. Depressing the actuator trig gers the switching operation, with a predefined force and travel. The switching speed itself is largely independent of the speed of actuation.

Actuator
Applying force to the actuator of a snap switch releases the snapaction mecha nism, which in turn triggers the switching operation.

Single Pole Single Throw Normally Closed (Break contact) Function In rest position the COM terminal is con nected to the NC contact. When the actu ator is depressed, COM and NC break contact and COM and NO make contact. When the switch is actuated, contact is made. When the switch is actuated, contact is broken. Graphical
Auxiliary actuator
It is possible to attach an auxiliary actua tor to a snap switch in order to meet the specific requirements of a given applica tion. Doing so usually alters the travel and forces involved in the switching operation, depending on the length of the levers. By attaching an appropriate auxiliary actua tor, it is possible to increase travel and/or reduce the actuating force required.
Contact gap (contact opening distance)
The contact gap is the distance between a pair of open contacts. For snap swit ches, it is usually around 0. mm. Gene rally speaking, for switches with contact gaps < mm, additional measures are necessary for separation from the mains. These switches bear the mark µ for Euro pean approvals. Switches with a contact gap > mm can generally be used directly for separation from the mains. Please check the device specifications applying to your particular product, and if there is any doubt, please clarify with the respon sible testing agencies.
Clearance and creepage distance
Clearance is the shortest distance through the air between two electrically conductive parts or between an electrically conductive part and a metal foil affixed to an access ible surface of some insulating material. The creepage distance is the shortest dis tance along the surface of an isolating ma terial between two electrically conductive parts or between an electrically conductive part and a metal foil fixed to an accessible surface of the insulating material.
Terminals
COM (Common = 1): Base terminal NC (Normally Closed = 2): The contact is closed in the rest position, that is, the terminal is connected to COM. When the switch is actuated, the contact opens. NO (Normally Open = 4): The contact is open in the rest position, that is, the terminal is separated from COM. When the switch is actuated, the contact closes.

Positions, forces and travels
Actuator positions
Dimensions for actuator positions are al ways specified in relation to a given refe rence line. Rest position The rest position is the position of the ac tuator when no external force is being ap plied. Sometimes referred to as the "free position". Operating point (mech.) The point along the actuator's travel path at which the springoperated mechanism is actuated. Final position (total travelled position) The position of the actuator at the end of its travel. Reset point (mech.) The point along the actuator's path, as it travels back to its rest position, at which the springoperated mechanism snaps back to its original position.
Actuator travel
Pretravel The distance travelled between the actuator's rest position and the switching point. Overtravel The distance travelled between the swit ching point and the end position. To make absolutely sure that the switching opera tion takes place, an actuator should use up at least 50 % of the available overtra vel. Reset travel The distance travelled between the end position and the release point. Free travel (open circuit travel) The distance travelled between the reset point and the rest position. Total travel The sum of pretravel and overtravel, or of reset travel and free travel. Movement differential The distance travelled between the opera ting point and the reset point.
15
Forces
Initial force The force required to move the actuator away from its rest position. Operating force The force required to move the actuator through the operating point. Sustaining force The force required to hold the actuator in its final position. Reset force The level to which the operating force must be reduced to allow the springope rated mechanism to return to its original position. Differential force The difference between the operating force and the reset force.

Operating life, temperature resistance, vibration and electric resistance
Operating life
The operating life specifies the minimum number of switch cycles within the speci fic values. It depends on a large number of parameters that are determined by the intended application case. Among these are, for example: · switched current and switching voltage · type of load (e. g. ohmic, inductive or lamp load) · Combination of materials in actuating element/actuator · Actuator type · Actuator speed · Switching frequency (switching cycles / min) · Pretravel / Overtravel · Environmental factors such as climate conditions or harmful gases (e. g. SO2) Please note: Media such as greases, oils and materials which contain silicon must not be used on the switch. There is a distinction between mechanical and electrical operating life.
Mechanical life
Indicates how often a switch can be actu ated without an electrical load. Mechani cal endurance is calculated by actuating the snap switches axially in relation to the actuator in a sinusoidal pattern using about 80 % overtravel at a switching frequency of 4Hz at room temperature.
Electrical life
The selection of the optimal contact mate rial has great influence on the operating life. The electrical life test is conducted at rated voltage, rated current and resistive load at 2 °C ambient temperature. The lower the electrical current, the longer the electrical life under some circumstances it may even equal the switch's mechanical life.
Please note: For switching loads which deviate from the values specified in the catalogue, we recommend that you discuss the issues involved with Cherry. This is especially important if you are using other consumers as linear resistances. These can be electrical circuits with inductive resistances (motors), capacitive resistances (condensers) or lamp loads. To ensure that a switch reaches the end of its electrical operating life, the switch should not be subjected to pressure in its rest position (pre-stressed) and at least 50 % of the available overtravel must be used. Operating life specifications for direct current loads are available on request. Where higher switching capacities are involved, we recommend the use of fuses to provide protection against arcing. Please note: Since the operating life of a snap switch depends on a number of factors, we recommend that field trials be performed in order to establish the likely electrical life of a switch in a given application. This is especially recommended when the application deviates considerably from the test conditions described above. Our specialists are always ready to provide you with more advice regarding possible solutions for your particular application.
17
Behaviour at different temperatures
Depending on the model, the operating temperatures of our switches range from 25 to + 70 °C and 40 to + 150 °C. If you attempt to use a switch at operating tem peratures either above or below those re commended for your particular model, the switch`s material properties will change and its reliability will be affected. Where switch model codes start with "T" (e. g. 40T125 in compliance with EN 61058), the switches involved have been approved for use at the corresponding temperatures.
Vibration and shock resistance
Snap switches are naturally fairly resistant to shocks and vibrations thanks to their minimal mass of moving parts. They are at their most resistant when the actuator is in the rest position or end position, when vibration resistance is as high as 5 g at 20 200 Hz while shock resistance attains 20 g (6 ms). Please note: Snap switches are more susceptible to vibrations at the switching point and at the release point. In certain conditions, this could result in transient make or break contacts (bouncing) to the detriment of the switch`s operating life. This is why snap switches which are regularly exposed to vibration should, wherever possible, not be actuated slowly.
Electric strength
The electric strength of our snap switches is in the case of models suited for mains voltages exceeds 1500 VAC between con ducting parts and the earth and 750 VAC between the terminals (open contacts) measured over a period of one minute at an ambient temperature of 2 °C ± 5 °C, relative humidity of < 70 % and normal at mospheric pressure.

Operation, contact types and materials
Operating speed
Snap switches are suitable for a broad spectrum of operating speeds. However, extremely slow or fast actuations can affect the switch performance and operating life. For productspecific values, please see the technical specifications. The maximum switching frequency (swit chings / s) is limited by the electric load. With low switch loads, up to 10 actuations per second are possible. Please note: Sudden actuation must be avoided since it decreases the mechanical operating life.
Transit time
In twoway (doublethrow) switches, transit time is the time between the moment the break contact element (NC contact) first opens and the make contact element (NO contact) first closes. Transit time is gene rally determined by design features such as e. g. contact travel and elastic charac teristics. It generally varies between 5 and 10 ms, depending on the model. Please note: If transit time is critically important to the functioning of your application, don`t hesitate to contact us.
Contact materials
Gold and gold alloys: primarily AuAg; AuAgPt Silver and silver alloys: primarily Ag; AgNi; AgPd Gold alloys are especially suitable for low currents and voltages. Typically they are used in the range from 5 V 1 mA DC to , 12 V 100 mA DC. But it may also make sense to use them in switches which are only occasionally operated or in atmos pheres with a high sulphur content. For switching heavier loads, it usually makes sense to use silver or silver alloys. In this case, the range typically extends from 12 V, 100 mA DC to 250 V 21 mA AC. Please note: Because choosing the right contact materials depends on a large number of factors, such as switching voltage and current, operating environment, atmospheric conditions, etc., we are always pleased to advise you on the best choice of material for your application. Before making any firm decisions, we do advise you to carry out field trials of our switches in real-life conditions.
Contact bounce
Bounce time is the time between the mo ment closing contacts first touch and final (definitive) contact closure. The typical bounce time for our snap switches is around ms.
Contacts
We supply switches with standard and crosspoint contact technology. For low voltage and lowcurrent applications, we strongly recommend the use of gold cross point contacts. The reduced surface area of the crossshaped contacts means that the surface pressure is greater, which in turn enhances reliability. Standard contacts are more suitable for higher switched loads.
19
Materials and contact resistance
Materials
For our standard switches, we use high quality, cadmiumfree plastics which are optimised for the intended application. As a rule, we seek to avoid the use of toxic or hazardous materials. You can find out more about our materials policy by con sulting our hazardous substances exclu sion list. Behaviour of materials in fire Insulating materials which are directly connected to electrically conductive parts are classified according to their degree of flammability. Most of the materials we use to manufacture housings are selfextingui shing and categorised under the UL 94 V0 standard. Tracking resistance Most of the insulating materials we use in our snap switches have a proof tracking index of PTI 250 (PTI 00 on request). This means that they are capable of 50 drops of test fluid at a test voltage of 250 V without producing any leakage current (IEC 60112). RoHS Switches without leads already conform to RoHS. Switches with leads are available in RoHSconforming models on request. In case of further processing with lead free soldering, the productspecific solder recommendations must be heeded. (For more information, see page 20). Glow wire test The insulation materials used for snap switches with ENEC approval fulfil the required filament tests GWFI according to the household appliance standard IEC 6051 at 850 °C and GWIT at 775 °C or alternatively the filament test GWT at 750 °C.
Contact resistance
The contact resistance of snap switches is composed of the contact resistance and the resistance of the conductive parts. It depends primarily on the construction and the contact material. The contact resistance of silver contacts is max. 100 m , of gold contacts max. 50 m when they are new. Insulation resistance The insulation resistance between the con ductive parts of our snap switches and a conductive underlay or between the open contacts exceeds 10 M when they are new, measured over a period of one mi nute at room temperature with 500 V DC. Caution: humidity and soiling can decrease the insulation resistance.

RoHS
RoHS (Restriction of the Use of Certain Hazardous Substances) designates the guideline 2002 / 95 / EG of the European Parliament and Council. This forbids the use of particular substances in electrical and electronic devices, which are brought to the common market starting in July 2006.
Switches as supplied by Cherry are not themselves subject to the guidelines, but they are suitable for use in devices of the categories mentioned above. Cherry, as a leading manufacturer, feels obligated to ensure that its customers have transpa rency for the greatest possible security in decisionmaking. Overview of the Cherry switches with respect to conformance with the RoHS regulation.
Note
Explanations: not contained 1) According to the exception granted by the EU Commission (published in the EU Journal L280/18 v. 25/10/05), the use of cadmium and cadmium compounds in electrical contacts is still permissible. 2) Processing after consultation with Cherry. Switches with leads are available in RoHSconforming models on request. In case of further processing with lead free solder, the productspecific solder recommendations must be heeded. ) Conversion of last PB and PE models by June 2006. All cited regulations represent the version at the time of printing. No liability is assu med for subsequent changes.
(Based on the natural degree of soiling, products can not be completely free of the forbidden substances. In the commission proposal (2004) 606 of 2. Septem ber 2004 to the Council of the European Union (EU), therefore, the following was proposed: "In the sense of Article 5, Paragraph 1, Letter a, a maximum concen tration value of 0.1 percentage weight of lead, quick silver, hexavalent chrome, polybromided biphenyles (PBB) or polybromided diphenylethers (PBDE) per homogeneous material and of 0.01 percentage weight cadmium per homogeneous material is tolerated.")

Assembly and installation
Please note: Cherry snap switches should only be installed by trained staff. Generally, adherence to the required air gap and creepage distance must be ensured with suitable measures. These must also be adhered to for lines connected to the switch. If installation is to occur on a conductive surface, insulating panels must be used. Under some circumstances, their use is also required between switches installed alongside one another and plugin con nections. Switches can be installed in any position. Power transmission to the con nections of the switch is not permitted. When fastening with screws, screws with a coplanar contact surface must be used. (e. g. in accordance with DIN 84, DIN 912). Smooth, solid surfaces are suitable for in stallation. Exceeding of the following tigh tening torque values is not permissible. We recommend trial installations. If you wish to install your switches using coupling pins, we would be happy to advise you on suitable parameters. Please note: If components are likely to be subjected to vibrations, we advise you to take additional measures to secure them. With solder connections, the product-specific solder recommendations must be heeded in order to prevent damage or destruction of the switches. Please note: Cleaning agents and solvents in proximity to the switches can impair their function, especially in case of watertight models. When using greases (especially mineral oil-based ones), we recommend consultation with Cherry. The switching action may be initiated by a force acting vertically on the actuator, or by an angled actuation lever. Example:
max. 30°
Please note: The actuator may not be pre-stressed when at rest. When actuated, the switch should travel well beyond the switching point. for at least 50 % of the predefined overtravel, in order to ensure that full contact is made. It is quite unacceptable for the switch to exceed the specified overtravel or end position. Using the switch as a mechanical end stop should be avoided. A high-impact actuation of the switch can have a negative effect on the switch`s mechanical life.

The angle of the lever in relation to the top of the switch housing should not ex ceed 0 °. The precise angle will also de pend on the actuating speed, combination of materials, surface characteristics and so on. In case of auxiliary actuators with rollers or simulated rollers, steps should be taken to ensure that the lever does not impede its own action. This means that the direction of actuation should be away from the actuator`s mounting point towards the roller, and the angle of actuation should be adjusted to allow for the geometry of the actuation system. We would always recommend a preliminary discussion with Cherry.

Description
Assemblies and combinations Individual switches in combination with endcaps can easily be built into block assemblies by integrated snap pins. Spacers and housings can be integrated in any given sequence. Stops Cherry provides many standard combina tions of rotationlimiting stops to help tailor our switches exactly to your application. In series PE stops can be installed in the field. Special circuit boards If you require a specially constructed PCB (special material, terminals, layout etc.), please consult the factory. Colours and legends The standard switch colour is black. The wheels are black with white characters. Special colors for housings, wheels and legends are available upon request. We are able to print letters, symbols or figures according to individual requirements. Circuitry Standard circuitry is breakbeforemake (bbm). For makebeforebreak (mbb), please consult the factory. Codes For standard codes please refer to indivi dual switch series. Further and special codes available upon request. Mounting of components Many standard codes are available with an extended PCB for mounting of diodes or resistors.
