ABSTRACT:
A rotary switch has a case, a housing, and a rotor rotatably arranged in a chamber of the housing. The housing carries a pair of projections on both side walls and a pair of corner projections together with a pair of grooves defined in the bottom center thereof, while the case has a pair of bent legs in the center of which are defined holes to receive the side wall projections of the housing and the undersurface of which extend to form a pair of depending lugs which may be crimped inwardly into a pair of grooves defined in the housing. A contact member positioned between rotor and the housing carries a plurality of contact fingers provided with contact projections having contact points one of which may be contacted, in accordance with the rotation of the rotor, on one of the terminal lead contacts spaced around the housing chamber caused by slidable touching on one of the contact projections by means of a cam pattern provided on a circuit board attached to the rotor.
