Abstract
An installation of a wiring device configured to receive a cover plate which snaps on to a wiring device such as a switch or receptacle. With this invention, openings for threaded fasteners in the face of the cover plate are eliminated. In an embodiment, the cover plate has an opening sized to accommodate a wiring device and supports, on opposing side walls of the opening, at least one protrusion. The protrusions on the cover plate are located to detachably engage corresponding protrusions on the wiring device as the cover plate is pressed onto the wiring device.
