  • Patent number: 6797907
    Abstract: A multi-position switch assembly mounted in a housing. The switch assembly includes a rotatable member, a set of first electrical conductors disposed along a first circumference and a set of second electrical conductors disposed on a printed circuit along at a second circumference. The switch assembly also includes an actuating mechanism that selectively provides electrical contact between at least one of the first conductors with one of the second conductors to close a circuit when the member is rotated. The first conductors may be either stationary or rotatable with the member. The actuating mechanism for the stationary conductors includes a cam, a bearing retainer and a pad with resilient buttons. The rotatable conductors are spring-biased and guided in a slot on the printed circuit board.
