An ground fault circuit interrupter includes two conductive wires, an AC-DC converter, a switch circuit, two annular magnets each having a induction coil, a signal treating and controlling circuit, a manual switch driving circuit, and an electronic switch driving circuit. The switch circuit is connected in series with the conductive wires for cutting off power to the output terminals of the conductive wires. The signal treating and controlling circuit electrified by the AC-DC converter receives signals from the conductive wires and sends out its controlled signal. The connecting point of the input of the switch circuit and the output of the signal treating and controlling circuit is connected in parallel with a manual switch driving circuit and an electronic switch driving circuit, for keeping safety of the electricity between the input of power and the output or a load.
