PACA-3400 Datasheet, PDF (1/8 Pages) Cherry Semiconductor Corporation – Assemblies and combinations, Special circuit boards

Description
Assemblies and Stops
combinations
Circuitry
Codes
Individual switches in
combination with endcaps
can easily be built into block
assemblies by
integrated snap pins.
Spacers and housings
can be integrated in any
given sequence.
Special circuit
boards
If you require a specially
constructed PCB (special
material, terminals, layout
etc.), please consult the
factory.
Cherry provides many
standard combinations of
rotation-limiting stops to
help tailor our switches
exactly to your application.
In series PE stops can
be installed in the field.
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.
Standard circuitry is
break-before-make (bbm).
For make-before-break
(mbb), please consult
the factory.
