Abstract
An electric switch operating mechanism has a base fastened over an aperture in the cabinet enclosing the switch. A driving member extends into a cup-like member and the ends of both members extend through the base and the cabinet aperture. The ends of the driving member and retainer cup have apertures therein which receive an end of the control shaft for the switch. The cup-like member is rotatable with respect to the driving member to captivate a retaining pin on the end of the control shaft. A handle with a locking plate is connected to the driving member and abuts the base. The handle can be rotated to rotate the control shaft. The locking plate can engage the base and the retainer cup to lock the operating mechanism in different positions. The mechanism in addition to operating the switch also provides an interlock function preventing the cabinet from being opened.
