Abstract: A power supply socket panel comprises a panel enclosure, at least one movable connector, a panel supporter and at least one elastic foot. The panel supporter is mounted to the movable connector, and together they are secured to a power supply socket or switch. The panel enclosure is secured to the panel supporter through the movable connector and the elastic foot is mounted between the panel supporter and the movable connector.

Only when the circuit interrupting device is properly wired, in a tripped state, and all of the key components in the circuit interrupting device are working properly, the depression of the reset button allows the device to be reset.

Abstract: The present invention relates generally to a leakage detection protective circuit. This leakage detection protective circuit includes a rectification circuit, a current-limiting resistance, a controlled silicon rectifier (SCR), a power supply main circuit switch linked with a reset button and a tripping coil with a built-in iron core. The rectification circuit, tripping coil, and SCR are connected in series with each other, forming a circuit. The control pole of the SCR is connected, through the current-limiting resistance and the diode, to the shielding layer of the power output wires. When a leakage failure occurs, the shielding layer connected to the control pole of the controlled silicon rectifier becomes electrified, triggering the controlled silicon rectifier. A magnetic field is then generated within the tripping coil and its built-in iron core moves, causing the reset button to trip. This invention is characterized by a compact circuit and robust operation.
