ABSTRACT:
An interlock for aligned switch members, which are movable toward each other to an ON position and away from each other to an OFF position, includes a pair of engagement members and a connector member extending therebetween. Each engagement member includes a planar retainer section which extends outwardly and is adapted for receipt within a passage defined by the switch member, for guiding axial movement of the engagement members relative to the switch members. Each engagement member further includes a pair of upstanding tabs, and the engagement members are positioned such that the tabs are located adjacent each other between the switches. The connector member includes an upper wall located above the plane of the retainer sections, and depending side walls which are interconnected with the tabs via screws which pass through openings in the tabs and into aligned, threaded openings in the depending side walls. The interlock is simple in its components and installation, and provides a strong, positive interlock structure which can be used in either an original installation or in a retrofit application.
