Overview

HE Series High Pressure switch, rising set point (factory set), 120 bar, M14 x 1.5 port, SPDT-NO/NC output with silver contacts, cold-rolled steel base, petroleum-based hydraulic fluid actuation, 1/4 in spade terminals.
These pressure switches are durable, reliable electromechanical gauge pressure on/off switches that are available with either single pole single throw (SPST) normally open or normally closed circuitry, or single pole double throw (SPDT) circuitry. Their high proof pressure and burst pressure ratings allow for use in many rugged applications that require the making or breaking of an electrical connection in response to a pressure change of the system media.
