| Abstract: |
A light control switch device for mounting in a wall box has a conductive front mounting plate arranged to overlap the edges of the wall extending around the opening receiving the wall box. Mounting-screw receiving openings are disposed in the wall plate, with one pair of openings aligned vertically centrally of the plate while two additional openings are formed on opposite sides of the center line of the plate, and in horizontal alignment with respective ones of the pair of centrally aligned openings. The spacing between a central opening and a laterally displaced opening is equal to one-half the distance between the screw-receiving openings of a standard wall box. The vertical edges of the wall plate are then provided with snap-off sections, where the distance between the two snap-off sections is equal to some multiple of the distance between the screw-receiving openings of a conventional wall box. Switch devices may then be ganged in a multiswitch wall box either with or without snap-off sections. The front surface of the conductive face plate contains heat-radiating fins.

The embodiments of the invention in which an exclusive privilege or
1. A conductive plate for mounting a switch; said conductive plate having first and second generally parallel surfaces; a switch means mounted on said first surface; said conductive plate having an elongated opening therethrough; said switch means having an operating member extending through said opening and operable from an area communicating with said second surface of said plate; said second surface of said conductive plate having a plurality of parallel fins extending therefrom; said plurality of parallel fins terminating in at least one plane spaced from and disposed generally parallel to the plane of said second surface; said plate being generally rectangular in shape; said plurality of parallel fins extending in a direction generally parallel to one pair of sides of said rectangular plate; mounting openings in said conductive plate adapted to receive mounting screws for mounting said conductive plate in an attitude wherein said parallel fins extend in a vertical plane; said mounting openings including a first pair of openings aligned vertically with one another along the center of said conductive plate and equally spaced from the top and bottom sides of said conductive plate, and third and fourth openings which are respectively spaced by equal distances from said top and bottom sides of said conductive plate, and by equal distances from each of the said one pair of sides of said plate which are perpendicular to said top and bottom sides, whereby said third and fourth openings form points on a line which generally passes through the geometrical center of said plate, and is at an angle, other than zero degrees, to the line joining said pair of openings; said first pair of openings and said third and fourth openings constituting the sole available openings in said conductive plate
