A multifunction six-way switch assembly having a plurality of sealed dome type or membrane switches disposed on a circuit board and arranged in pairs such that a single knob actuator may be slidably moved in opposite directions along a first axis for actuating either one of a first pair of membrane switches and slidably moved in opposite directions along a second perpendicular axis for actuating either one of a second and third pair of membrane switches in the same direction for controlling seat adjustment servomotors. Rotation of the single-knob actuator about a third axis normal to the first two axes results in a mutually opposite direction of actuation of the second and third pair of membrane switches. The six-way actuator has only one portion extending externally of the switch housing for attachment of the user knob.

A fluid pressure operated servomotor having a housing shell containing a flexible diaphragm forming a fluid pressure chamber with a port through the housing connectable for receiving a fluid pressure signal. The diaphragm has a rigid insert extending therethrough and sealed thereabout with a cup shape on the interior of the chamber and having a rod pivot surface formed on the exterior side of the diaphragm. A spring inside the chamber has one end registered in the cupped shape to bias the diaphragm insert in one direction. In one embodiment, the insert is shaped to have a rod pivot surface nested in the coils spring such that the rod pivot load resists lateral buckling of the spring; and, in another embodiment, a shroud is formed on the insert about the rod pivot surface for limiting rotation of the insert with respect to the rod end.
