Abstract: The present invention provides a safety device for socket, which comprises a switching circuit, a control module, and a detection module. The switching circuit is coupled between a supply main and an internal transmission structure of a socket. The control module is coupled to and controls the switching circuit. The detection module is coupled to the control module and outputs a detection signal. The control module controls the turning-on or cutoff of the switching circuit according to the detection signal. When the plug is not inserted into the socket, the control module cuts off the switching circuit. Then the power source from the supply main will not be transmitted to the internal transmission structure of the socket. After the plug is inserted into the socket, the control module turns on the switching circuit. Then the power source from the supply main will be transmitted to the plug via the switching circuit and the internal transmission structure of the socket. Thereby, the sparks can be avoided for preventing danger as well as extending the lifetime of the socket.
