Abstract
Abstract A cap and wall structure for sealing a toggle switch against entry of moisture. The cap comprises an annular skirt encapsulating an annular wall formed about an opening in the wall structure or cover plate. The cap includes a pair of legs which lock it to the wall or plate but allows the cap to slide while a pair of tabs entrap the switch actuating member to actuate the same in response to movement of the cap.

Total Claims: 16
Claim 1
Independent Claim
234 words
In combination, a wall structure having an opening frmed therein, an annular forward facing wall forming a border about the opening, a toggle switch arranged within the opening and having a forwardly projecting planarly shiftable actuating member, and a moisture sealing cap, said cap comprising a substantially forwardly facing wall, an annular skirt rearwardly depending from the forwardly facing cap wall, the depth of said skirt from the rear surface of said cap wall being at least equal to the forward facing depth of the annular wall, said annular skirt having the same annular shape as the annular wall, the skirt in a plane parallel to the plane of movement of said member being longer than said annular wall so as to form a clearance space for movement of said member, and in a plane normal to the plane of movement of said member the interior width of said skirt is substantially equal to the exterior width of said annular wall, said cap including a pair of legs spaced from the skirt parallel to the plane of movement of the member depending rearwardly into the opening beyond the wall structure, each of said legs including means for securing the cap to the wall structure while allowing the cap to slide in the plane of member movement, and means in the cap for entrapping the member so that movement of the cap moves the member.
