ABSTRACT:
A redundant power controller including two sets of switches, one of which is electrically controlled and the other is controlled manually. The electrically controlled switch is a relay-controlled switch which when detecting an abnormal input voltage, it sends out a positive voltage to cut off the power supply to the system. The mechanical switch is controlled manually to cut off the power supply to the system when needed.
