(*) Sound intensity is given as a reference, switch isolated, out-
side any additive part such as PCB, button, etc. The sound
intensity after product integration may change according to
the surrounding parts. For other features, please refer to the
KSC Series data sheets.
Note for ST2 versions: This actuator contains carbon particles
and therefore is electrically conductive. Please consult factory
for list of compatible materials to be used while designing
button on top of the switch.
Other versions in terms of force, termination length and
corrosion protection are available. Please contact your sales
representative. This data sheet does not provide enough
information for applications which r
equire a certain level of
quality or safety such as automotive, medical
systems, safety
equip
