Its robust and hard-wearing design ensures a long service life, also under high loads. Thanks to the compact design, the standardised device coupling, and the high IP protection class, the pressure switch is particularly suited for use in series production of vacuum, pneumatic, and hydraulic systems. Pressure adjustment is done by the customer (precisely as required), and the switching point is continuously adjustable via a screw.
