Abstract
A disc designed to be placed between a light bulb and the bottom of a mating Edison socket into which the light bulb is screwed is capable of attenuating power by rectifying alternating current to the bulb in one mode and in another mode is capable of passing full current to the bulb. Thus, by lightly screwing the bulb into the socket, the bulb glows dimly, its power being supplied through the rectifier. When the bulb is more tightly screwed into the socket, the disc is compressed and the device applies full power to the bulb. The switching is accomplished by offsetting the rectifier and allowing pressure exerted between the light bulb's center contact and the bottom of the socket to operate a switching mechanism, preferably located at the center of the disc. The switching mechanism shunts the rectifier in the full-power mode of operation.
