DESCRIPTION
The diaphragm pressure switches in the PM Series are available in two
versions: one with Normally Closed (NC) contacts and one with Normally
Open (NO) contacts. A regulating screw, which can be adjusted using a
small screwdriver, allows the switch to be set to the required pressure.
The calibrated diaphragm enables an electrical signal to be generated or
inhibited, depending on the pressure set.
