MAP - hydro-electric pressure switches with a fixed switching pressure differential. The mechanical microswitch with gold plated contacts grants high reliability and long life service. 

The microswitch changes its status when the pressure in the hydraulic circuit reaches the switching value set on the adjusting knob. The microswitch returns to the original rest position when the pressure in the hydraulic circuit drops below the nominal fixed switching pressure differential (hysteresis). The electric connector provides both NC AND NO contacts.

The pressure in the circuit operates the piston acting against the adjustable spring; once the set pressure is reached, the piston actuates the microswitch. The pressure switching value is selectable by a graduated adjusting knob. Clockwise rotation increases the set pressure.
