Electromechanical Pressure Switches

Common features: Reliability

Stable set points, constant hysteresis and safe electrical operation are standing-out features of all pressure switches made by HERION & RAU Fluidtechnik GmbH – this applies to all products of the bar-control series.

HERION & RAU Fluidtechnik GmbH uses only rugged and accurately working snap action micro switches with friction-optimised mechanics that is suitable for high switching capacity but also for low electric voltage and currents.
