ABSTRACT:
In the design of electrical switchboards or control panels or the like there are employed push buttons for the actuation of a switch for performing a desired control function or operation. There is disclosed a push button containing a solid or rigid front impact flange member and a rear impact cam or detent which is arranged at the tip of a tongue-like spring member or resilient tongue and possesses an inclined guide surface. The push button can be mounted in the cover plate of an assembled switchboard or control panel or the like, without the need for any auxiliary tools, and is positively self-retained thereat without there being required access to the rear side of the cover plate or to the interior of the switchboard panel. A spring-biased support member of a switch arranged rearwardly of the cover plate presses the push button at its near impact surface against the rear side or face of the cover plate and retains such in the desired rest position. The push button can be again dismantled, with the aid of extraordinarily simple means, out of a completely assembled together unit without there being necessitated any access to the rear side of the cover plate.
