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.
