The switch comprises a housing with a housing top side supported on the back side of the mounting plate, a fastening protrusion including fastening means, as well as a plurality of resilient tongues, each having a locking protrusion. The fastening protrusion and the resilient tongues are inserted for mounting purposes from behind into an opening of the mounting plate, with the locking protrusions locking in place with the front edge of the opening. Furthermore, the device comprises a fastening element that can be mounted from the front side of the mounting plate and cooperates with the fastening means of the fastening protrusion. According to the invention the resilient tongues extend from the housing top side substantially in vertical direction and are spaced apart from the fastening protrusion. Moreover, according to the invention the fastening element is formed by a sleeve that can be inserted from the front side of the mounting plate into the opening of the mounting plate.
