ABSTRACT:
A revolving safety socket of the present invention has a uniquely-designed stand, which serves as a switching device. It consists mainly of a circular hole in the case cover and a circular recess in the case base. Located between the circular hole and the circular recess is a revolving stand having receptacles therein. When the socket is not in use, the conductive member of the revolving stand is not in contact with the copper clip which is connected to the power supply. Only when a plug is inserted into the revolving stand, which is then rotated for a 90-degree angle, would the conductive member become engaged with the copper clip to permit the power supply to be on. Additionally, the socket has the reversed L-shaped fasteners to hold the protruded block of the plug firmly in place, ensuring that the plug can not be accidentally pulled out of the socket.
