Keymodule
Cherry key modules are mechanical
input elements with a single-gap
make contact element. Low assembly
height, pleasant feel and excellent
contact reliability thanks to Gold-
Crosspoint contact technology allow
flexible designing of low-cost keypads
and keyboards. Depending on the
key cap, different lead spacings are
also possible.

Very short bounce times, very
pleasant feel and exceptionally high
reliability and durability pave the way
for a wide range of applications.
