Abstract
A housing (50, 52) defines a slide chamber (54) in which a slide member (34) reciprocates between three positions. A coil spring (86) holds the slide member (34) into a center position. In this position, slide member (34) blocks fluid flow through a port (28) and positions an electrical conductor (96) away from electrical contacts (110, 112). A push on the slide member (34) moves the electrical conductor (38) into circuit making contact with the contacts (110, 112). A pull on slide member (34) moves an exhaust passageway (36) in the slide member (34) into communication with the fluid port (28). The switch function activates a compressor which pumps air into an inflatable seat actuator. The valve function exhausts air from the inflatable seat actuator.
