Abstract
A three-way light dimmer switch is shown wherein the brightness of a lamp or lamps is controlled by independent light dimmer switches with each dimmer switch having its own light dimmer circuit. Each of the light dimmer switches is vertically actuated with one end of the vertical movement turning the lamp or lamps ON, and the other end of the vertical movement turning the lamp or lamps OFF. Between the limits of vertical movement, either of the light dimmer switches may vary the voltage potential received by the lamp to thereby adjust the brightness of the lamp.
