Lutron Electronics D-603P-WH 600 W 120 Volt White 3-Way Incandescent/Halogen Rotary Dimmer with Push Knob

The original solid-state dimmer, introduced in 1961, sets lights for the perfect mood or ambiance. Rotate to select light level, and either rotate or push to on/off. The Rotary dimmer is available in single-pole models, where the lights are controlled from one location and 3-way models, where the lights are controlled from more than one location. There are also models available with the eco-dim® feature, which guarantees at least 15% energy savings compared to a standard switch.
