Dimmer Switches

Shop dimmer switches at RS Electrical Supplies. Dimmer switches allow you to adjust the brightness of your lighting to suit the mood, time of day, or task — reducing energy consumption and extending bulb life at lower settings. We stock dimmer switches from leading UK manufacturers including BG Electrical, Scolmore Click, and ML Accessories (Knightsbridge), available across all standard decorative finishes and gang sizes.

Dimmer Switch Types Available

• 1-gang dimmer switches — single dimmer controlling one lighting circuit
• 2-gang dimmer switches — two independent dimmers on one plate, controlling two separate circuits
• Leading edge dimmers — suitable for traditional incandescent and halogen bulbs
• Trailing edge dimmers — suitable for LED and low-voltage lighting; smoother, quieter operation
• LED compatible dimmers — specifically designed for use with LED lamps; check minimum and maximum load ratings
• 2-way dimmer switches — for controlling one dimmed circuit from two locations

Dimmer Switches by Finish

• White moulded — standard choice for domestic and commercial installations
• Matt Black — bold contemporary finish for modern kitchens and design-led spaces
• Brushed Steel / Stainless Steel — versatile satin metallic finish
• Polished Chrome — high-gloss finish for contemporary interiors
• Satin Brass & Antique Brass — warm metallic finishes for period and transitional interiors
• Black Nickel — dark metallic finish for contemporary and boutique interiors

Important: Always check the minimum and maximum load rating of your dimmer switch against the total wattage of the lamps on the circuit. LED lamps have a much lower wattage than traditional bulbs — using a dimmer with too high a minimum load can cause flickering or buzzing. Order today with fast UK delivery from RS Electrical Supplies.
