Screw-In Pressure Switch

Compact design, versatile solutions: The screw-in pressure switch from HERION & RAU is designed as a modular system. From the switch point to the connection, you decide on the configuration. You define the switch point via the adjustment screw or receive it pre-configured ex works. A range of materials and designs is available for the membrane, housing, fluid connection, and electrical interface, tailored to the medium, temperature, and installation situation. This ensures you get a switch that precisely matches the pressure range, operating environment, and required service life.
