Abstract
A combined electrical switch and fluid control device is disclosed, for simultaneously performing electrical and fluid power control functions. For example, the device may be employed on an automotive vehicle for controlling the operation of electrical components and vacuum operated devices. The control device is particularly well adapted for controlling the operation of a heating and air-conditioning system for an automobile or some other automotive vehicle. The control device may comprise a casing, a control member movable in the casing along a predetermined path, electrical switching means in the casing and operable by the movement of the control member along such path, fluid control means in the casing and including a valve member movable in the casing in a direction transverse to the path of the control member, and camming means operable between the control member and the valve member for moving the valve member transversely to such path in response to movement of the control member along the path. The valve member may have passages therein for selectively interconnecting a plurality of valve ports, formed in the casing. The electrical switching means may include fixed contact…
