ABSTRACT:
An improved column mounted switch for vehicles and the like for controlling the windshield wipers and the windshield washer in an automobile or truck. One or more rotatable carriers are in electrical contact with a base member having electrical conductors. The rotatable carriers also have conductive member means which can enter into and pass out of electrically conductive relation with the electrical conductors to act as a switch having multiple functions. The carrier may comprise shaped portions of a conductive metal plate, with the shaped portions being embedded in an insulating plastic disc. Thus the shaped portions form a part of the smooth face of the disc which can smoothly rotate in contact with the electrical conductors of the base, while an added contact may be provided to the carrier by means of a conductive ring, as part of the conductive metal plate, exposed to the other side of the carrier for contact with other conductive member means. The design of this application permits the elimination of one carrier and cover, when compared with switches of the prior art having similar functions.
