Abstract
An apparatus for mounting an electrical switch in a cut-out of a switch board comprises a support ring between the switch body and the rear side of the switch board, the support ring surrounding the axially extending switch grip and having claws arranged for engagement with the cut-out at the front side of the switch board. An axially biased housing is mounted between the support ring and the rear side of the switch board, with springs pressing a circumferential portion of the housing against the rear side of the switch board. A coupling ring between the support ring and the switch grip has a radially outwardly directed groove in engagement with a radially inwardly directed rib on the support ring whereby the coupling ring is held against axial movement by the support ring.
