Mechanical pressure switches with a diaphragm sensing element for converting pneumatic or hydraulic signals into an electrical switching signal.

The pressure switch is suitable for universal use in vacuum applications. The process connection is 1/8" as standard. The case and connection are made of brass. An adjusting screw allows setpoints to be easily adjusted in situ. The setpoint can optionally be factory preadjusted. The integrated microswitch allows switching performance of up to 5 A. As an alternative, gold-plated contacts are available for low switching currents.

The economical construction with flat connectors is designed specifically for use within equipment. A protective cap can be ordered as an accessory to raise the degree of protection to IP 54.
