This finish is made to change and age with wear, making each switch unique, differing from batch to batch. We strongly advise ordering items for the same room together to ensure consistency. If fitted to plastered walls, there is a chance the dampness will encourage the finish of this switch to corrode.
Add depth, control and an architectural edge to more complex lighting schemes with our Blackened Steel Quadruple Dimmer Switch.

A Blackened Steel Quadruple Dimmer Switch is made for larger spaces where lighting needs to do more, bringing four separate controls together on one beautifully finished plate. It’s a practical way to simplify more complex lighting layouts, while also giving the wall a stronger, more characterful finish. Hand-finished in-house, the darkened steel surface brings timeworn depth and an industrial heritage feel, creating a fitting that feels established and fully considered within the room.
The feeling This is the kind of detail that makes a layered lighting scheme feel more intentional. With four dimmers arranged on one plate, the wall looks calmer and more resolved, while the Blackened Steel finish adds a darker, more grounded note than standard black. It feels architectural and quietly rugged, with the sort of timeworn character that helps a room feel more settled and more complete.
Where it works best Perfect for larger rooms or open-plan spaces where multiple lighting zones need independent control. Think kitchen diners with pendants, downlights, wall lights and under-cabinet lighting, or larger living spaces where practical and ambient lighting need to shift throughout the day. A quadruple dimmer makes those transitions feel easier, while keeping the wall finish cleaner and more cohesive.
Why it works More complex lighting layouts can quickly create visual clutter if every circuit needs its own switch. A quadruple dimmer keeps everything contained within one plate, giving you independent control over each lighting zone without interrupting the flow of the room. In Blackened Steel, that practical function also adds a stronger material presence, helping the switch feel like a deliberate part of the design rather than something that simply blends away.
The design detail The Blackened Steel finish is hand-finished in-house, creating a darkened steel surface with depth, variation and a timeworn quality that feels rich rather than flat. It has an industrial heritage feel and an aged, established look that makes it more characterful than a standard black finish. Even with four dimmers, the balanced proportions and clean detailing keep the overall look calm and composed, turning a highly practical fitting into a strong architectural detail.
How to style it Pair it with matching Blackened Steel switches and sockets for a cohesive look across the room, particularly in interiors built around darker materials and more grounded finishes. It works beautifully with raw timber, concrete, stone, deep charcoals, plaster tones and layered neutral palettes, where the finish can add weight and structure without feeling too severe. If you want the room to feel more established, atmospheric and materially rich, Blackened Steel brings exactly that kind of depth.
