1. A pressure sensor apparatus, comprising:
a hybrid pressure switch provides 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,
wherein the mechanical pressure switch comprises a micro-switch, wherein when the single switching point is attained, the micro-switch is actuated and functions as a change-over contact.
