摘要： A vacuum switch for interchangeably connecting a plurality of vacuum lines includes a vacuum housing having a plurality of ports to which the vacuum lines are connectable. The vacuum housing has a plurality of channels molded in one surface of a plate and communicating with the ports. Each channel has at least one passage through the plate to the opposite surface. The channels are arranged to provide the desired fluidic logic. A one-piece seal member seals the channels to maintain a vacuum therein. A plurality of valves are slidable upon the surface of the plate opposite the channels. Each valve has a cavity providing fluid communication between passages when the cavity spans a pair of passages. Electrical contacts, movable with the valves, activate a circuit to provide an electrical signal corresponding to the desired mode selected for the vaccuum lines.
