If the usage and operation conditions specified in the datasheet are not met, the component may be damaged or dissolved. • Do not drop or impact the components, the component may be damaged. • Prevent any damage or scratches on the switch, especially on the actuator. • Würth Elektronik products are qualified according to international standards, which are listed in each product reliability report. Würth Elektronik does not warrant any customer qualified product characteristics beyond Würth Elektroniks’ specifications, for its validity and sustainability over time. • The responsibility for the applicability of the customer specific products and use in a particular customer design is always within the authority of the customer. All technical specifications for standard products also apply to customer specific products. Product specific: Soldering: • • • • The solder profile must comply with the technical product specifications. All other profiles will void the warranty. All other soldering methods are at the customers’ own risk. Please keep our switch at delivery original position before and during the soldering process. Design the right angle part with consideration of the wave soldering process so that the parts will not touch the soldering wave during the soldering process or protect the switch part with cover fixture. Melt of the switch might cause malfunction. If the parts are washable, hermetic: • Cleaning agents used to clean the customers’ applications, may damage or change the characteristics of the component, body, pins and/or termination. • Please do not immerse any washable products into water or cleaning agents nor put them in locations exposed to water completely. • Do not clean washable series immediately after soldering. The cleaning agent may be absorbed into the switch through respiration while the switch cools. • Please do not press actuator or change status/position during the cleaning and washing process. • Using a brush during the cleaning process may deform function relevant areas. Therefore, we do not recommend using a brush during the PCB cleaning process. Potting and Coating: • If the product is potted in the customer application, the potting material may shrink or expand during and after hardening. Shrinking could lead to an incomplete seal, allowing contaminants into the body, pins or termination. Expansion could damage the components. We recommend a manual inspection after potting or coating to avoid these effects. Storage Conditions: • A storage of Würth Elektronik products for longer than 12 months is not recommended. Within other effects, the terminals may suffer degradation, resulting in bad solderability. Therefore, all products shall be used within the period of 12 months based on the day of shipment. • Do not expose the components to direct sunlight. • The storage conditions in the original packaging are defined according to DIN EN 61760-2. • For a moisture sensitive component, the storage condition in the original packaging is defined according to IPC/JEDEC-J-STD-033. It is also recommended to return the component to the original moisture proof bag and reseal the moisture proof bag again. • The storage conditions stated in the original packaging apply to the storage time and not to the transportation time of the components. Packaging: • The packaging specifications apply only to purchase orders comprising whole packaging units. If the ordered quantity exceeds or is lower than the specified packaging unit, packaging in accordance with the packaging specifications cannot be ensured. Handling: Cleaning and Washing: • If a series is washable, the general information section in the datasheet will contain the washability guidelines. Should there be no information regarding washability, the product has not been constructed to withstand a washing process. Washing agents used during the production to clean the customers’ application might damage or change the characteristics of the component, body, pins and/or termination. Washing agents may have a negative effect on the long-term functionality of the product. • The switch shall be assembled while in OFF state. • The effector should be positioned so that direct force is not applied to the actuator on its free position (NC circuit). The operating force to the actuator should only be applied vertically. • For NO (Normally Open) circuit, the actuator should be pressed down at least until it reaches the pre-travel or Operating Position (OP position). To reduce possible errors, it is recommended to reduce the lowest tolerance of the operating position (OP) by further 0.2 mm.

Other ways of operation may lead to malfunction or break the switch. • Actuator type should be selected according to the activation method, activation speed, activation rate and activation frequency. 1) A slower activation speed than commonly used may cause unstable contact transfer, possibly resulting in contact failures or contact fusion. 2) A higher activation speed than commonly used may cause damage to the contacts or contact response failure. • Use of a driving (roller type) mechanism, which may cause physical impact to the actuator, shall be avoided. • When wiring the micro-switch, the proper wire for the applied voltage and current must be chosen. During the wiring process, it must be ensured that the power supply is switched OFF. • Continuous exposure of the switch to vibration or shock may result in contact failure or fault operation due to abrasion powder and resulting in reduced durability. Excessive vibration or shock will lead in malfunction of the contacts or even get damaged. • When mounting holes for 12.8 mm, use M2 mounting screws with washers to mount the switch. Do not tighten the screws with a torque over 0.1 N∙m. • When mounting holes for 19.8 mm, use M2 mounting screws with washers to mount the switch. Do not tighten the screws with a torque over 0.26 N∙m. • After mounting and wiring, check the insulation distance between terminals and ground. If the insulation distance is inadequate, insulating material in between is required. • The switch shall not be mounted upside down. It may lead to wrong interpretation of the free position and can cause malfunction of the use of the switch. • The micro-switch contact may experience bouncing or chattering during the switching. Bouncing or chattering can cause noise or pulse count errors, when the snap action switch is used in an electronic circuit. Chattering behavior may vary depending on the speed of operation. Our definition of 10 ms is according to the term of our test with a speed of 100 mm/minute and measure on total travel position. • All our reliability tests are measured in free position for (NC) and in total travel position for (NO). • Our switches are not suitable where hydrogen sulfide or other corrosive gases are present. Non-washable types are also not suitable for dusty environments. • Condensation will occur inside the switch if there is a sudden change in ambient temperature, when used in an atmosphere of high temperature and high humidity. • The temperature rise of the component must be taken into consideration. The operating temperature is comprised of ambient temperature and temperature rise of the component.The operating temperature of the component shall not exceed the maximum temperature specified. These cautions and warnings comply with the state of the scientific and technical knowledge and are believed to be accurate and reliable. However, no responsibility is assumed for inaccuracies or incompleteness.
