Definition:  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.

Description:  1. A device which completes, interrupts, or changes the connections in one or more electrical circuit(s) by electrical, electronic, manual or mechanical actuation, or as a result of changes in ambient temperature. It includes items consisting of individually separable switches which are physically interlocked (e.g., one button returns when the other is pushed), which have a common actuator, or are electrically connected. Excludes: items which perform the same function by self-produced thermal action, such as relays, circuit breakers, fuses, or motor starters.
