KSC5 Tact Switch with Rocker Option for SMT
The KSC5, normally opened miniature
Tact switch, is an extension of the broad
KSC SMT series.
The KSC5 is based on the same exter-
nal dimensions as the standard version
and can be actuated either from the top
or from the side. This eliminates the
need for a right angle mechanism or an
additional PCB.
Main Features
Applications
4
2 actuation modes: axial and lateral
Tin plated terminals for an easy and
reliable soldering
