ABSTRACT:
An electric switch having a disc which is rotatable to any of several indexed positions, the disc having two generally semicircular conductive sectors rigidly attached to the disc and electrically insulated from each other; a plurality of stationary terminals, one of which is in continuous sliding contact with one of the sectors, one of which is in continuous sliding contact with the other sector, and the remaining terminals are in discontinuous sliding contact with one or the other of the sectors; the sectors being shaped to eliminate electrical contact with selected terminals at selected indexed positions of the disc.
