Switching function:
One single-pole micro switch (change-over switch)
The pressure increase closes contacts on terminalss 1 - 3 and opens
contacts on terminals 1 - 2
Ordering Code
Pressure switch consists of an aluminum housing,
a piston, a prestressed spring and a microswitch.
When the pressure corresponding with the spring setting
is reached, the switch closes or opens the respective
electric circuit.
The pressure switch is being supplied with a connector
and with two bolts.
When delivered with a sandwich plate, the switch can be
turned around its length axes by 90°.
The subplate can be ordered separately or with the
switch.
