suited to the following methods:
– Cleaning according to typical washing processes.
– Lead free reflow soldering process in accordance with IEC 61760-1.
NOTE:
Specifications listed above are for switches with standard options. KSE series is not
subject to adaptation and/or modification for specific use. If you require additional
features, please refer to the KSC series. KSE is not recommended for applications
requiring high level of performance such as aerospace, automotive and some
industrial applications.
NOTE: For cost effectiveness the tactile feeling is not speci-
fied and can change along production. If your application
requires a defined tactile effect, please consider KSC series
for your application.
