Abstract

The invention relates to a switch having a switch housing, a number of module-type individual interrupter chambers which can be arranged in particular side by side in the switch housing and having at least two switching contact elements, and an actuating device which closes off the switch housing above the individual interrupter chambers. This actuating device serves to adjust a cam element for the selective establishment of an electrical connection between the switching contact elements of an individual interrupter chamber. The switching contact elements can be arranged in at least two different orientations in each individual interrupter chamber in an explosion-protected manner. Furthermore, in particular the cam element of the actuating device can be arranged differently depending on the orientation of the switching contact elements. This results in a switch with a simple adaptation option for housing installation or front-panel mounting, wherein all requirements for explosion protection are also fulfilled at the same time.
