Abstract
A multiple contact switch including an elongate contact member mounted for sliding movement. A pair of contact posts are positioned beneath the sliding contact member and a contact ball is arranged between the contact posts with the sliding contact member resting on the ball and moving the ball into contacting relation with the two posts. A third contact post has a cam surface and a sliding contact member has a cam surface adapted to cooperate with the cam surface of the post to lift the sliding contact member out of contact with the ball as the sliding contact member makes contact with the contact post having the cam surface.
Claims5
A multiple contact switch comprising a housing, a sliding contact bar mounted in said housing and connected to an external source of power, means extending into said housing for reciprocating said contact bar, a pair of contact posts mounted in closely adjacent but spaced apart relation in said housing and having external electrical connections, a ball adapted for contact with either of said contact posts selectively, said contact bar engaging said ball to move said ball from contact with one of said contact posts to contact with the other of said contact posts and thus establish a connection between the contact bar, the external source of power, the contact posts and the external connections, and means extending into said housing engaging said contact bar for biasing said contact bar into engagement with said ball.
