Leviton Trimatron lighting controls are traditional rotary style dimmers that are renowned for their compact, easy to install design and outstanding reliability. Trimatron dimmers are only half as deep as many conventional rotary style dimmers, providing an easy fit even in shallow wall boxes. They are furnished with wire leads to further speed installation. Trimatron dimmers are available in 1-pole (one location) and 3-way (multi-location) Deluxe push-On/push-Off versions for incandescent lighting and fan speed control. The Trimatron line also includes rotary On/Off dimmers and quiet fan speed controls.
