A power control module including a socket, a switch circuit and an interface control circuit is provided. A plug is adapted to be inserted into the socket, and the socket has a positive terminal, a first negative terminal and a second negative terminal. When the plug is inserted into the socket, a negative terminal of the plug sequentially contacts the first negative terminal and the second negative terminal. The switch circuit receives a power voltage through the positive terminal. The interface control circuit determines whether to generate a switching signal to the switch circuit according to a voltage level of the second negative terminal. When receiving the switching signal, the switch circuit outputs the power voltage. |
