Abstract (en)
The present invention relates to a hydraulic or pneumatic pressure differential electric switch, comprising a switch body defining herein a chamber which can be arranged between two hydraulically or pneumatically pressurized regions. In the chamber is tightly movable, under the pressure differential between the mentioned two regions, a movable electric contact cooperating with a fixed electric contact supported by the switch body through a dielectric spacer element. The movable electric contact is moreover acted upon by counter-biassing resilient means. <IMAGE>
