This electronic component has been designed and developed for usage in general electronic equipment only. This product is not authorized for use in equipment where a higher safety standard and reliability standard is especially required or where a failure of the product is reasonably expected to cause severe personal injury or death, unless the parties have executed an agreement specifically governing such use. Moreover Würth Elektronik eiSos GmbH
& Co KG products are neither designed nor intended for use in areas such as military, aerospace, aviation, nuclear control, submarine, transportation (automotive control, train control, ship control), transportation signal, disaster prevention, medical, public information network etc.. Würth Elektronik eiSos GmbH & Co KG must be informed about the intent of such usage before the design-in stage. In addition, sufficient reliability evaluation checks for safety
must be performed on every electronic component which is used in electrical circuits that require high safety and reliability functions or performance.
Cautions and Warnings:
The following conditions apply to all goods within the product series of Tact switch of
Würth Elektronik eiSos GmbH & Co. KG:
General:
• This mechanical component is designed and manufactured for use in general electronic equipment.
• Würth Elektronik must be asked for written approval (following the PPAP procedure) before incorporating the components into any
equipment in fields such as military, aerospace, aviation, nuclear control, submarine, transportation (automotive control, train control,
ship control), transportation signal, disaster prevention, medical, public information network, etc. where higher safety and reliability are
especially required and/or if there is the possibility of direct damage or human injury.
• Mechanical components that will be used in safety-critical or high-reliability applications, should be pre-evaluated by the customer.
• The component is designed and manufactured to be used within the datasheet specified values. If the usage and operation conditions
specified in the datasheet are not met, the wire insulation 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.
If the parts are washable, hermetic:
• Cleaning agents that are used to clean the customer applications may damage or change the characteristics of the component, body,
pins and termination.
• Please do not immerse any washable products into water or cleaning agents or 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.
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. Melting of the switch might cause malfunction.
Handling:
• In the case a product requires particular handling precautions, in addition to the general recommendations mentioned here below, these
will appear on the product datasheet.
• Do not repeatedly operate the switch with excessive force. It may damage or deform the switch resulting in malfunction.
• Please set up the switch in such a way that the actuator will operate in a straight vertical line. A decrease in the lifetime of the switch
may result if the actuator is pressed off-center or from an angle. This might cause function errors or broken actuators, especially for
heights over 7.0 mm.
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.
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 customer 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.
