Abstract

Electrical switch gear which comprises a housing formed to be substantially rotationally symmetrical and consisting of an upper housing part and a lower housing part. Inside the housing is disposed an actuating member formed as a push rod, provided in a housing chamber and provided with a permanently magnetized component, and a switching component which can be influenced by the permanently magnetized component and is provided in one housing chamber hermetically separated from the other housing chamber. To create switching gear able to make possible a larger number of switching functions, at least one permanently magnetized component is provided which is disposed on one longitudinal side of the actuating member and extends with its region of action close to one of the separating wall sides extending in the displacement direction of the actuating member. In addition to the one switching component provided on the other separating wall side, at least one further switching component is provided in the other housing chamber and is located in front of or behind the one switching component in the displacement direction of the actuating member.
