Abstract: A modularly constructed motor vehicle control stalk 10 comprises a handle base 20 that engages any of a plurality of vehicle steering column switch actuator assemblies 14. The base 20 accommodates an interchangeable trim sleeve 48 for styling the control stalk 10 to be cosmetically compatible with any of a variety of vehicle interiors. The trim sleeve 48 is secured to the base 20 and supported by a standardized stalk handle 56 which also acts as a receptacle for a switch knob 84 for actuating any of a variety of vehicle operator functions. The switch knob includes interiorly mounted contacts which engage contact surfaces of a printed circuit board when the switch knob is compressed or rotated.

Abstract: A variable resistance switch utilizing a resistor network (40) and discrete electrical contacts. A thumbwheel position selector (50) having a detent follower (58) coacting with a series of detents (22) is utilized by an operator to feel the detent follower index between detents as the thumbwheel switch is rotated. Electrical contacts are made with discrete inputs to a resistor network for selecting a discrete resistance value based upon the position of the thumbwheel.
