Abstract
An interlock assembly for a safety switch includes a linkage. A first end of the linkage is coupled to the operating handle of the safety switch in order that moving the operating handle results in a corresponding movement of the second end of the linkage into and out of an aperture in a bracket member. The bracket member is movably coupled to the safety switch enclosure by a fastening mechanism. When the cover of the safety switch is disposed in its open position, the bracket member is disposed in a first position preventing the second end of the linkage from entering the aperture and resisting undesired movement of the operating handle. When the cover is closed position, the bracket member is moved to a second position corresponding to the second end of the linkage being receivable by the aperture in order that the operating handle is movable.
