  • Rotary switch with reflector coded actuator drum
    Patent number: 4634861
    Abstract: A multi-position rotary switch comprises an actuator drum divided into a plurality of different n-bit codes where each bit is represented by a reflective area or a non-reflective area on the drum. The drum is radiated by a suitable emitter and radiation reflected off of the drum by reflective bits is detected by a plurality of radiation detectors. The drum is rotatable to bring the different n-bit codes into view of the radiation detectors. Each different n-bit code detected by the radiation detectors is indicative of a particular switch position.
