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 construed for washing, so
washing can cause a malfunction afterwards.
For our washable series WS-TSW
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.
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 endanger to be 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 , it could
cause damage or deformation of the contact dome and result to
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
