Abstract
An electric switch mounted within an enclosure having a hinged cover is manually operated from outside the enclosure by a handle mechanism secured to the enclosure. The cover is provided with a single aperture near the edge thereof remote from the cover hinges, with this aperture providing clearance for the operating handle of the mechanism when the cover is closed and also providing clearance for a catch which holds the cover closed. The mechanism also includes a defeatable cover interlock to prevent opening of the cover when the switch is closed, and a defeatable switch interlock to prevent closing of the switch when the cover is open.
