| Abstract: |
A structure for facilitating the gripping and operating of a control lever of an electrical switch plate mounted into an electrical box embedded into a wall. The structure comprises a movable plate having a large central projection. The projection defines a trough in which the control lever engages, and two large abutting surfaces opposite the trough and orthogonal to the wall, the plate being slidable within a plane parallel to the wall. A cover is fixedly secured to the electrical box by its square central section the plane of which is interiorly offset with respect to the main body of the cover. The central section is upwardly and downwardly open to enable sliding action of the movable plate parallel to the wall, within the plane of the cavity. Thus, the movable plate hides the control lever as well as the screws that secure the cover to the electrical box, and is retained by the guide walls of the cover. In accordance with the invention, a modular covers assembly is also provided for use with electrical plugs as well as electrical switches. These various modules are interconnected by dovetailed connectors.

I claim:
1. In combination, an electrical switch having a frame from which transversely projects a toggle control lever, and a switch operating member for facilitating the gripping and operating of the control lever, said operating member comprising: a cover having a main body surrounding a central cavity, said cavity defining a small plate having a central opening through which releasably extends said control lever and securing means for securing said small plate to said switch frame, the plane of said small plate being offset toward said switch frame with respect to said main body plane and defining upper and lower slits between the small plate and the main body; and a larger plate having a large central projection, said projection defining a trough in which said control lever is releasably engaged and two large opposite abutting walls alternatiely engaged by said toggle lever upon pivotal action of said lever, said larger plate being positioned against said small plate and being engaged into said slits so as to be able to slide therebetween during pivotal action of said control lever.
