ABSTRACT:
An exclusive plug for artistic table lamps comprising main parts, namely a signal input line, two voltage output lines, a demagnetizing wire, a light-adjustment and switch-actuating operational circuit, and electric power indication light, of which the signal input line and two voltage output lines use a co-axial core cable, and a demagnetizing wire is provided around this three-core cable. The light adjustment and switch-actuation operational circuit is installed in the body of the plug, thus making the plug of this invention, when used in conjunction with a general artistic table lamp, convert the overall external surface of the common artistic table lamp stand into a touch induction surface. This device is completely applicable to the artistic table lamp, no matter whether the table lamp stand is made of a material of low induction coefficient like ceramics, pottery, marble, glass, wood, plastics etc., or even of metallic materials.
