Description
Switch,code Indicating Wheel
CAGE
93322

A switch which is externally actuated by a thumbwheel and/or pushbutton. A legend or message is visually displayed at each position of the indicating wheel which corresponds to electrically coded output. Electrically coded output is achieved by rotating a set of brush contacts permanently attached to the code indicating wheel, against a stationary commutator which is usually a printed wiring board having electrical pads or contacts which are interconnected by the rotating brush contacts. May have additional electrical components (such as resistors, capacitors, diodes) premounted on that portion of printed wiring board which extends beyond the back of switch housing.
