Abstract
A three-way toggle dimmer circuit controls the brightness of a lamp by independent operation of two light dimmer switches with each dimmer switch having its own electronic light dimmer circuit. Each of the light dimmer switches is arcuately actuated with one end of the vertical movement changing the electrical interconnection between the light dimmer switches. The other end of the vertical movement changes the internal electrical characteristics within the light dimmer circuit itself. The electronics of the light dimmer circuits are controlled by the position of a toggle arm through a linear slide potentiometer including both a variable slide resistor and a miniature internal switch.
