Abstract
The secondary cover of a molded case electric power switch housing is removably secured in place to enclose cavities in a primary cover for auxiliary devices by quick release fasteners. These quick release fasteners have a shaft with self taping threads which engage mounting holes in the top face of the primary cover. In an unlatched position, the non-circular heads register with complimentary non-circular apertures in the secondary cover which passes down over the heads of the quick release fasteners and seats on the top face of the primary cover. The quick release fasteners are then rotated clockwise ¼ turn by a tool to a latched position to clamp down on the secondary cover. A pair of diametrically opposite arcuate recesses in the secondary cover at each non-circular aperture assure that the quick release fasteners can only be rotated clockwise to the latched position as side walls of these recesses form stops at the ¼ turn position.
