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.
