Our 3-Gang Brass Dimmer Switch Is Best For

• Living rooms, dining rooms, kitchens, and open-plan spaces with three lighting zones
• Layouts with overhead light, accent light, and wall or task light on one plate
• Bedrooms or primary suites where ceiling light, sconces, and bedside lighting need separate control
• Projects that coordinate dimmers with matching outlets, sockets, combo plates, or a brass toggle
• Rooms that mix decorative and functional fixtures for a more layered result

How to Choose

Choose this layout when you need three dimmers side by side, such as separate controls for pendants, ceiling lighting and wall lights. Each lighting load must be compatible with its selected dimmer; three gangs do not mean three-way switching.

1. Confirm each circuit: single-pole is for control from one location. If the same lighting is controlled from two locations, have your electrician confirm the required 3-way arrangement and companion device.
2. Select Dimmer Type: the current options are Single Pole and Single Pole / 3-Way. Check the complete selection before adding it to your cart. If the three positions require different device types, ask us to confirm a mixed layout.
3. Check the lighting combination: confirm the exact bulbs or drivers, dimming method and permitted load against the selected model’s instructions.
4. Choose the finish: use the same finish label across matching hardware. Aged Brass and Unlacquered Aged Brass are separate options.

Before You Buy

This product uses Leading Edge (TRIAC) dimming. A bulb labelled “dimmable” is not enough to confirm compatibility: check the exact bulb or driver and the selected dimmer’s instructions before ordering. Do not choose this model for a lighting system that requires trailing-edge/ELV or 0–10V control. For smart lighting or an uncertain combination, ask your electrician and contact us before purchase.

• Use dimmable bulbs only
• Fits standard U.S. wall boxes
• Available in single pole and 3-way options
• Made for 3-gang layouts
