Precautions for the use of Tact Switch Revision 2 Valid from 07.05.2002 page 3 of 5 This document is only valid on the date of printing: 18/01/2016 2.3 Recommendation for hand soldering: 350°C for 3 sec. max 2.4 Recommendation of vapor phase soldering Our Tact Switch Products are not qualified via VPH. Qualification of usability must be approved on customer side for this process, gladly with free samples offered by Wuerth Elektronik. 2.5 Cleaning, Washing and Coating For non-washable series Parts out of this series are not constructed for washing, so washing can cause malfunction afterwards. For our washable series *1 Please do not submerse our washable products into water or cleaning agents or put them in locations exposed to water completely. When cleaning by hand (brushing), please do not use excessive force on our switch to avoid malfunction afterwards, because you could deform function relevant areas or you could damage sealing functions. Do not clean washable series immediately after soldering. The cleaning agent may be absorbed into the switch through respiration while the switch cools. *1 : washable series 12 x 12 mm : 430 4x6 0xx 7x6 6 x 6 mm : 430 4xx 0xx 8x6 ; 431 4x1 031 8x6 Precautions for the use of Tact Switch Revision 2 Valid from 07.05.2002 page 4 of 5 This document is only valid on the date of printing: 18/01/2016 If our product is potted in customer applications, the potting material might shrink during and after hardening. Accordingly to this the product is exposed to the pressure of the potting material with the effect that the product is possibly damaged by this pressure and so the electrical as well as the mechanical characteristics are in danger of being affected. After the potting material is cured, the products needs to be checked if any malfunction or destructions on the product have occurred. 3. Handling of the component Do not repeatedly operate the switch with excessive force as it could cause damage or deformation of the contact dome and result into malfunction. Please set up the switch so that the plunger will operate in a straight vertical line. A decrease in the life of the switch may result if the plunger is pressed off-center or from an angle. Also it may cause function errors or broken actuators, especially for height of more than 7.0mm 4. Storage & operation condition Storage temperature: -40°C ~ 85°C Operation temperature : -40°C ~ 85°C Precautions for the use of Tact Switch Revision 2 Valid from 07.05.2002 page 5 of 5 This document is only valid on the date of printing: 18/01/2016 5. Packaging Our SMD parts are generally packed on tape on reel. Our THT parts are generally packed in bulk and sealed in plastic bag. For details packaging information, please refer to our catalogue or specification. 6. Compliance Wuerth Elektronik products are RoHS compliance products.
