ABSTRACT:
A waveguide switch is provided in which energy such as ultrasonic optical, electromagnetic or infrared waves travel in a first waveguide having fixed length formed in a first member connected to a second member having multiple waveguides of varying lengths which may be rotatably mounted to the first waveguide in order that upon rotation of the first or second member, different waveguides may be aligned to form an overall position identifying waveguide of varying lengths in order to provide a means for controlling a component attached to the switch. A transmitter and a receiver are mounted within the waveguide and connected to a detector in order to convert the time-of-flight data of the waves to an electrical signal.
