摘要： A rotary vacuum-electrical switch controller is particularly applicable for use in an automatic temperature control system in a motor vehicle for selectively interconnecting various vacuum and electrically operated accessories with a vacuum source or an electrical source. The controller includes a valve body including a valve seat having a generally flat circular surface with a plurality of valve ports formed therein. A plurality of valve nipples are connected to the valve ports and the nipples extend from the valve body for connection to a vacuum source and vacuum control devices. A disc-shaped valve plate has a circular surface which faces the valve seat and has a plurality of chambers defined therein by peripherally encompassing radially and circumferentially extending walls. The chambers selectively interconnect various of the ports as the valve plate is rotated. A rotor is coaxially aligned with the valve plate and has a first end with means for engaging the valve plate for rotating the valve plate about its axis of rotation. An electrical switch body is provided with a generally flat surface having a plurality of electrical leads mounted thereon. A disc-shaped electrically conductive switch plate is interposed between a second end of the rotor and the switch body. The rotor has means for drivingly engaging the switch plate so that as the rotor is rotated about its axis of rotation, the switch plate is rotated along with the valve plate with the switch plate selectively interconnecting various of the electrical leads as it is rotated.
