Pressure Switches with
Mechanical Interlock of the
Switching State
Fig. 10. Mechanical interlock
Max. pressure switch ABC*...-205
Min. pressure switch ABC*...-206
Instead of the microswitch with automatic
reset, the limiters feature a "bistable"
microswitch.
When the pressure reaches the value set
on the scale, the microswitch switches
over and remains in this position. The
catch can be released by pressing in the
20
unlocking button (marked on the scale side
of the switching device by a red dot). The
limiter cannot be unlocked until the
pressure has decreased by a certain
amount or, in the case of interlocking at the
lower switching point, is increased again.
Depending upon the version, the interlock
can be effective for a rising value (ABC*...-
205) or for a falling value (ABC*...-206).
*stands for DCM, DNM, DNS, VCM, VNM,
VNS, and DDCM
