Abstract: In a rotary switch having a plurality of switch contact pads disposed in an arcuate array around an aperture formed through a base member, a rotor and switch contact assembly mounted for rotation in the aperture. The assembly includes a nonconductive disc having a flat surface thereon and a hub section extending outwardly substantially normal to the surface of the disc. The hub is divided into at least two separate hub sections which extend through the aperture. The protruding ends of the hub sections are barb shaped thereby preventing withdrawal of the hub and rotor disc from the aperture of the base. A shaft is positioned within an opening in the disc and between the hub sections thereby locking the rotor within the aperture. A resilient contact member, supported on the surface of the disc, traverses an arcuate path on the surface of the base to sequentially contact the switch pads on rotation of the rotor assembly.
