ABSTRACT:
A switch, as for a windshield wiper, has a housing, a carriage rotatable in the housing in opposite directions from a first position to respective second and third positions, one or more electrical contacts mounted on and moving with the carriage, a conductive contact surface fixed in the housing for engagement by the contacts moving with the carriage, a primary actuation member which is manually actuatable from a first to a second position and may control a windshield washer, a drive member carried by the primary actuation member along a path, a resilient reaction member affixed to the carriage and extending into the path of the drive member for engagement therewith and displacement thereby, and wherein the carriage is displaced from the first to the second position by the displacement of the reaction member. The reaction member is the cantilevered arm of a torsion spring. When the carriage is manually actuated through its first position toward its third position, the cantilevered arm of the torsion spring engages a stop member, such as the drive member of the primary actuating member, and yields to allow displacement to the third position but provides a return bias to the first position when the manual actuating force is released.
