ABSTRACT:
A multi-position switch comprising a housing which positions and generally encloses a rotator having a plurality of axially spaced cam tracks provided with collective, circumferentially staggered primary recesses for cooperating with detent portions of resilient conductors also positioned within the housing and in operational contact with the rotor so that the several circuits of the device may be selectively activated by the engagement of a selected conductor with a common contact. Each of the rotor cams is further provided with a plurality of intermediate, secondary recesses for resilient engagement with the remaining conductor detents so as to assure the switch will not become inadvertently positioned between contact positions thereof, and to further impart a more positive feel to the rotor as it is moved through its multiple positions by the appliance operator. The housing also includes means in the form of a longitudinally oriented bar for simultaneously urging the resilient conductors toward contact engaging position with the common contactor terminal.
