Abstract
In an arrangement for front mounting of pushbutton switching devices by means of a front ring screwed by means of its internal thread onto an external thread of a collar, the diameter of the disc shaped pushbutton is larger than the diameter of the external thread of the collar. The front ring has inward protruding extensions and the pushbutton itself has cut-outs at its circumference corresponding to the extensions. The pushbutton has a large actuating area without increase in the thread diameter.
