Switches, knobs, and handles are the jewellery of a room. How to use them to lift a space, with Buster + Punch as the reference.
You can spend a fortune on a renovation and still have it feel unfinished, and usually the reason is the small stuff: plastic light switches, builder-grade handles, a bare bulb. The pieces you touch every day are the ones that quietly signal quality. This guide is about that layer — the hardware and switches that finish a room — using Buster + Punch, a London brand that made these details a design statement, as the worked example.

Why the small things carry the room
Big surfaces — walls, floors, cabinets — set the backdrop. But the eye lands on contrast and detail, and nothing draws it like metal against a matte wall. A solid metal switch or handle reads as considered in a way a plastic one never can. Swapping these is one of the highest-impact-per-pound changes you can make, precisely because they're at hand height and in constant use.
Switches: the upgrade people forget
Almost everyone leaves the standard white plastic switch in place, which is exactly why changing it stands out. A metal toggle switch — brass, steel, black — turns a functional necessity into a deliberate detail. Buster + Punch's signature is the knurled (cross-hatched, machined) toggle, a texture borrowed from tools and motorcycles that's become its calling card. Placed on a plain wall, it does a disproportionate amount of work.

Build a coherent metal story
The trick to hardware isn't buying one nice thing — it's consistency. Pick a metal and a finish and carry it through the room:
- Choose one metal family — brass for warmth, steel for cool minimalism, black for drama — and stick to it across switches, handles, and fixtures.
- Match the finish — polished, brushed, or matte — so pieces read as a set.
- Repeat the detail — if you commit to knurled toggles, echo that texture in the cabinet knobs and pulls. Repetition is what makes a room feel designed rather than decorated.
A consistent metal thread ties a room together more cheaply and effectively than another piece of furniture.
Where to start
You don't renovate the whole house at once. High-impact, low-effort starting points:
- The switch by the door you see every time you enter a room.
- Kitchen cabinet handles and knobs — heavily used, highly visible.
- A statement bulb in an exposed fitting, where the fixture is the decoration.
Get one room's metal story right and it sets the template for the rest.

Frequently asked questions
Do designer switches really make a difference?Out of proportion to their size, yes. They sit at hand height and in constant view, so a solid metal switch signals quality where a plastic one signals afterthought — for a fraction of a renovation's cost.
How do I choose a metal?Brass for warmth, steel for cool minimalism, black for drama. The key is picking one family and carrying it consistently through the room.
What's the knurled detail?The cross-hatched, machined texture on Buster + Punch toggles and knobs — borrowed from tools and engineering. It's grippy, tactile, and the brand's signature look.
Where should I start?The switch by the door and your kitchen cabinet hardware — high-visibility, high-touch, and quick to swap. Nail one room, then repeat the finish.
The bottom line
The difference between a room that looks finished and one that doesn't is usually in the details you touch — switches, handles, and fixtures. Pick one metal, carry it through, and let a signature texture repeat. It's the cheapest way to make a space feel intentional. To see how the details come together, have a look at Buster + Punch.
