  • Remotely controlled toggle switch
    Patent number: 6031301
    Abstract: A simulated toggle switch capable of being set and reset by remote means and being manually operated. Control signals are received by two on-board electronic drive circuit assemblies which cause two corresponding magnetic solenoids to drive two cams clockwise or counterclockwise, independently of each other. This, in turn, causes a bat handle to move to an uppermost position, a lowermost position, or to be centered. In addition, the position of the switch is remotely sensed.
