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.

An inflation/deflation system, comprising: an inflatable including a combination inlet-outlet; an electric air compressor including an outlet; a combination valve and switch; an electrical control circuit for the compressor including said switch; an air exhaust system for said inflatable including said valve and an exhaust passageway leading from said inflatable in which said valve is located; wherein said combination valve and switch includes a single control member movable to close the switch and make the compressor functional for delivering compressed air to the inflatable, and also movable for opening the valve to exhaust air from the inflatable; wherein the inflatable is an air bag within a vehicle seat; and wherein the combination valve and switch further comprises: a housing including a slide chamber, a first fluid port bounding the slide chamber, a second fluid port spaced from the first port and also bounding the slide chamber; a three position slide member in said slide chamber, said slide member including a passageway which communicates the two ports when the slide member is in a first of said positions and a portion which blocks flow between the two ports when the slide member is in the second and third of said positions; a pair of spaced apart electrical switch contacts carried by said housing; a circuit making conductor carried by the slide member and positioned to engage both of the switch contacts when the slide member is in its third position, said conductor being in a circuit breaking spaced relationship from these contacts when the slide member is in its first and second switch position; wherein the second position of the slide member is a neutral position in which the valve is closed and the switch is opened; wherein movement of the slide member from the second position to the first position opens the valve with the switch remaining open; wherein movement of the slide member from the second position to the third position closes the switch with the valve remaining closed; and an inlet passageway in said housing leading to the first fluid port; and said system including a conduit connecting said inlet passageway to the inlet-outlet of said inflatable; and wherein said second fluid port of said valve is disposed to discharge to atmosphere.
