  • Remotely controlled simulated linear circuit breaker assembly
    Patent number: 6139327
    Abstract: A remotely controlled simulated linear circuit breaker capable of being set and reset remotely, and manually operated. Control signals are received by an on-board controller circuit card assembly. The signals will cause a plunger located in a solenoid housing to do one of two things. Either it will be extracted out of the solenoid housing, thereby popping the simulated circuit breaker, or it will be pulled into the solenoid housing, thereby resetting the simulated circuit breaker. In addition, the position of the switch is remotely sensed.

  • 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.
