Description
Assemblies and
Stops
Circuitry
Codes
combinations
Individual switches in
combination with endcaps
can easily be built into block
assemblies by
integrated snap pins.
Cherry provides many
standard combinations of
rotation-limiting stops to
help tailor our switches
exactly to your application.
Standard circuitry is
break-before-make (bbm).
For make-before-break
(mbb), please consult
the factory.
For standard codes please
refer to individual switch
series. Further and special
codes available upon
request.
Spacers and housings
can be integrated in any
given sequence.
In series PE stops can
be installed in the field.

etc.), please consult the
factory.
Colors and
legends
The standard switch color is
black. The wheels are black
with white characters.
Special colors for housings,
wheels and legends are
available upon request.
We are able to print letters,
symbols or figures
according to individual
requirements.
