Abstract
The disclosure is of electronic apparatus having a keyslot in its housing, by which it is coupled to a mounting screw. To protect the electronic circuitry inside the housing, the keyslot is covered internally by a layer of insulating paper and a thin metal sheet which overlies the paper and which is cemented to the surface of the housing adjacent to the keyslot. With this arrangement, the keyslot is accessible externally of the equipment for insertion of a screw; however, the inner circuit elements are completely and permanently sealed off from the outside world.
