<p>There is disclosed a wall plate (138) comprising part of a robust electrical wiring device system which overcomes the above noted deficiencies. A wall plate is disclosed which has a single opening (100) for positioning around one or more than one wiring device and has no dividing or separating members within the single opening for positioning or aligning the wiring devices. The wall plate (138) is formed with, along its vertical axis, a contour of positive first differential and zero second differential, comprised of a combination of what are termed herein splines drawn between points of varying distance from a datum plane. The contour has zero second differential when the rate of height increase of individual splines is constant. When the wiring device located within the wall plate is a switch, the contour of the switch face follows and blends with the contour of the wall plate so as to form a unitary combined aesthetically pleasing appearance. When the wiring device is a receptacle, the contour along the receptacle face is flat in one plane to allow for the proper seating of an inserted plug.</p> |
