ABSTRACT:
An anti-static switch lock wherein a terminal assembly having the desired configuration of rotor and contacts is secured to one end of a hub. The other end of the hub has an inboard lipped boss forming, in cooperation with the hub end, a circumscribed radial groove. A keylock assembly includes a barrel, one end of which has a chamber to receive the boss of the hub, and a key operated, rotatable plug. The hub, having the terminal assembly attached to one end, is positioned such that the groove is disposed within the chamber of the barrel. A number of stakes are formed in the barrel, the stakes engaging the groove to firmly secure the hub to the barrel. The plug is inserted into the barrel, the end of the plug interlocking with the shaft of the terminal assembly rotor to effectuate switching of contacts. To bias the plug, a spring mount which mounts a coil spring is interposed between the plug and the shaft of the rotor for the terminal assembly, one end of the spring engaging a catch on the hub to urge the rotation of the plug and shaft.
