The diaphragm pressure switches in the PM Series are available in two versions: one with NC (normally closed) contacts and one with NO (normally open) 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.
