Combination Rotary Dimmers and Toggle Switches by Forbes & Lomax

The Multi Set (2-Gang) by Forbes & Lomax is a combination rotary dimmer and toggle switch plate, blending 1930s brass-and-nickel switch aesthetics with modern dimming capability. Each set pairs a smoothly adjustable rotary dimmer with a toggle switch on a shared plate. Toggles and dimmers can be interchanged on the plates during installation to suit specific room configurations.

The rotary dimmer manages up to 120 W of LED lighting (or 300 W incandescent/halogen). Toggle switches are available in 3-way and single-pole configurations, rated at 15 A. Standard sets ship with 3-way toggles (can be wired single-pole). 4-way toggles available on request. In 3-way or 4-way circuits, dimming is possible from one location only — remaining switches function as non-dimming toggles.
