Our pressure switches are
also available with factory
pre-set switching points.
Ready-wired versions can be
found starting on page 38
following.
We offer other body
materials and connecting
threads upon request.
Other diaphragm- / seal
materials are available on
request, e.g. HNBR or silicone
for diaphragm pressure
switches.
For further technical data
see page 26/27.
Accessories see page 28
Piston pressure switches are only to a limited extent suitable for use with gases.
See explanation on page 9.

Static pressure, dynamic pressures should be 30 to 50% lower. These values refer to the hydraulic or pneu-
matic part of the pressure switch.
