Description

The Knightsbridge 1-gang dimmer plate is an 87.5mm square screwless faceplate in polished brass, supplied with a matching polished brass metal dimmer cap. The plate is unpopulated, meaning it accepts either centre-mounted or offset dimmer modules depending on wiring configuration and preference. The screwless cover clips onto a separate metal sub-frame, giving a clean finish with no visible fixings once installed.

Designed for residential dimmer installations in living rooms, dining rooms, bedrooms and hallways, the plate suits both traditional and contemporary interiors where a warm metallic accent is wanted. The polished brass finish reflects ambient light and develops a subtle patina over time unless polished regularly. The plate projects just 4.3mm from the wall once fitted, sitting nearly flush with plaster.

The premium-grade steel construction includes a built-in gasket between the cover plate and the sub-frame, which helps seal against dust ingress and gives a tighter fit against the wall surface. The plate carries an IP20 rating for dry indoor use and comes with a 25-year warranty. The matching metal dimmer cap coordinates with the faceplate finish, avoiding the visual mismatch of a plastic control on a metal plate.

Frequently Asked

Does this plate include the dimmer module itself?

No. This is an unpopulated dimmer plate, meaning you need to purchase a compatible Knightsbridge dimmer module separately. The plate accepts both centre and offset module positions depending on your wiring setup.

What back box depth is required?

The plate fits standard UK back boxes. The 4.3mm projection means the total depth from wall surface is minimal, but check the specific dimmer module you intend to use for its back box depth requirement, as that will determine the overall installation depth.

Is the screwless plate removable for redecorating?

Yes. The cover plate clips onto a metal sub-frame fixed to the back box. The cover can be removed for painting or wallpapering around the switch and re-clipped without disturbing the wiring.

Does the polished brass tarnish over time?

Polished brass develops a natural patina with exposure to air and handling. Some users prefer this aged look; others maintain the high shine with occasional polishing using a brass cleaner. The finish is lacquered to slow tarnishing, but the lacquer will wear over time with regular contact.
