Abstract

A pressure-operated switch for switching a connected assembly on and off comprises a spring dome (1), which contains a mechanical switching mechanism, and comprises an interrupter (9) that is actively connected to said spring dome. The invention is characterized by having a module (3) consisting of a device (6) for recognizing voltage and/or current of the load energy flow, of an evaluation unit (7) connected thereto, and of a switch for tripping the interrupter (9).
