Mechanical parts used in conventional switches to index stepper motor that drives switch elements are replaced by optoelectronic indexing device that controls magnetic-detent motor. Unit eliminates major source of wear and maintains detent accuracy longer. Design of device achieves reduction of insertion loss, crosstalk, and wave guide reflections when receiving and transmitting.
