Abstract

A pressure sensor apparatus and a method of operating the pressure sensor apparatus can include a hybrid pressure switch having a single switching point, the hybrid pressure switch comprising: a mechanical pressure switch; and an electronic pressure sensor, wherein the hybrid pressure switch monitors a media pressure with the mechanical pressure switch providing a switching function and the electronic pressure sensor providing a continuous pressure measurement with respect to the media pressure based on a continuous pressure output signal. The switching function can comprise a fail-safe switching function or a non-fail-safe switching function.
