An electronically-operable door strike employing a guard clip for deterring picking of the locking mechanism therein, a springless solenoid designed to avoid the undesirable build-up of residual magnetism and which incorporates air gaps for dissipating heat, thus prolonging the useful life of the solenoid, and a face plate for mounting the strike into a door jamb.

Electronically-operable door strike with guard clip, springless solenoid and face plate

An illuminated electrical push button switch has a pair of spring contacts secured in a plug-like body on either side of a miniature bulb. A flat top, metallic cup-shape, push button overlies the contacts, insulated therefrom by a sheet of electrical insulating material. The push button has a plurality of circumferentially spaced radially projecting fingers. A cylindrical shell with a radially inwardly directed flange fits over the plug-like body with a snug fit with the flange overlying the fingers of the push button to secure the push button to the body. A plurality of circumferentially spaced notches in the flange of the shell provide openings through which light emanating from the lamp can escape. The entire assembly has a low profile and is mounted by means of an adhesive. The assembly can be mounted directly on the building structure or it can be mounted with a decorative plate or the like interposed between the building and push button assembly.
