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.
A multi-circuit switch for use with household appliances and the like comprising a generally enclosed housing, a rotor journalled at the ends thereof and generally enclosed by said housing and adapted for at least partial rotation with respect to said housing, a plurality of generally parallel resilient conductors supported by said housing transversely thereto and in contact with said rotor, said rotor intermediate the ends thereof having a plurality of axially spaced circumferential cams collectively having circumferentially staggered primary recesses, each of said cams further having a plurality of spaced peripheral secondary recesses of lesser depth than said primary recesses so as to form cam surfaces having alternating peaks and valleys, each said conductor having an intermediate detent portion thereof to selectively engage said primary recesses successively so that upon rotation of said rotor to any position thereof, at least one of said detents engage a primary recess and the remaining detents engage a secondary recess, said housing including stationary contact means for selective engagement by said conductors when the detent thereof engages a primary recess.
A multi-circuit switch for use with household appliances and the like comprising a housing including a first housing member having opposed upstanding end and opposed upstanding side walls, a rotor journalled at the ends thereof in said end walls and adapted for at least partial rotation with respect to said housing, said rotor intermediate the ends thereof having a plurality of axially spaced circumferential cam tracks, a stationary contact supported along one of said side walls, a plurality of generally parallel resilient switch conductors supported by the other of said side walls at a first end thereof and outwardly extending to means intermediate the ends thereof for contacting said cam track positioned in alignment therewith and terminating in a contact at the other end thereof in position to engage said stationary contact, and a second housing member cooperating with said first housing member to generally enclose said switch, said second housing member including means for contacting upper portions of said conductors intermediate said first end and said cam track contacting means for simultaneously urging said switch conductor contact ends into engagement with said stationary contact, said conductor cam track contacting means serving to hold a plurality of said switch conductor other ends out of contact with said stationary contact at any given time.
