Abstract: A socket has one or more socket members received in an enclosure, and a current indicator disposed in coupled to the socket members for indicating the current through the socket members and for indicating the overload of the socket. The current indicator includes a coil, and a rotatable indicator to be actuated by the coil to indicate the current of the socket. A device may detect the temperature of the socket and a device may generate a warning signal when the socket is overload. The indicator may shield a photoresistive member when the socket is overload.
