ABSTRACT:
A switching device for a multi-filament electric lamp. The filaments of the electric lamp are electrically connected to arcuate contact surfaces arranged in a circle. The conductive bar is arranged to rotate about the axis of the circular arrangement of contact surfaces. The ends of the conductive bar contact the contact surfaces, and an electric power supply is electrically connected to the center portion of the conductive bar. Current flows into the center portion of the bar and out both ends and through the filaments of the electric lamp in the patterns determined by actuation of a pull-chain to operate the lamp in LOW, MEDIUM, and HIGH states. With the conductive bar in a further, pull-chain determined position, the lamp is OFF.
