Three Circuits, One Black Plate
This 3G dimmer switch lines up three independent rotary dimmers behind a single black plate, each carrying Buster + Punch's diamond-cut cross knurl. It is built for a wall position that would otherwise need three separate switches.
Choose Your Finish
The plate stays black across all three positions on this listing. The knobs and collars can all be black for one unbroken dark plate, or set in brass or steel so the three controls stand out as bright points against the black background.
How It Works
Three rotary dimmer modules sit behind the plate, each wired independently to a standard 230 to 240V, 50Hz supply. Each one dims LED bulbs from 5W up to 120W, or incandescent and halogen bulbs from 60W up to 400W, and controls its own circuit without affecting the other two. As with all hardwired Buster + Punch electrics, installation should always be carried out by a qualified electrician.
Where It Works Best
A 3G plate suits an open plan kitchen diner or living space where ceiling, wall and accent lighting are wired as three separate circuits but need to sit at one wall position. Instead of a row of three single switches, this gathers all three into one wider black plate, which is the main advantage of going 3G rather than fitting three 1G plates side by side.
Made By Buster + Punch
In 2013, having already worked as an architect at practices including Foster + Partners, Massimo Buster Minale founded Buster + Punch on the back of evenings spent hand building motorbikes in a Shoreditch garage, machining every part himself rather than buying it in. A three module plate like this is a clear result of that habit: each dimmer built as its own working part, not moulded into a single fixed block.

Questions People Ask
Can I control three completely different rooms from this one plate?
You can wire each of the three modules to a different circuit, so yes, as long as each circuit is run to the same back box. Your electrician can confirm what is practical for your existing wiring.
What bulbs can I dim with this switch?
Dimmable LED from 5 to 120W, or incandescent and halogen from 60 to 400W, per module. Check your bulb is marked dimmable first, since a non dimmable LED will flicker rather than dim smoothly. See our complete guide to why lights flicker for more.
Do I need an electrician to fit this?
Yes. This is a hardwired fitting connected to your mains lighting circuit, and it should always be installed by a qualified electrician.
