  • Waveguide switching system comprising a single stator and a plurality of rotatable waveguide switches therein
    Patent number: 5053732
    Abstract: A waveguide switch assembly having a common stator in which a network of signal paths are provided inserted by rotors operated by individual motors responsive to a digital computer. An interface including a line receiver the input of which is coupled to the output of the computer. A one-shot multivibrator is coupled to and triggered by the line receiver. A relay driven by the one-shot controls application of current to the switch motor when the computer applies a differential input across the line receiver. A timer and a counter is used to prevent the switch motor from exceeding a defined duty cycle.
