Description

The Knightsbridge 1-gang dimmer plate is an unpopulated steel faceplate with a matching matt black metal dimmer cap, designed to accept either centre-mounted or offset dimmer modules sold separately. The plate measures 85.75mm square with a 7.5mm projection from the wall once fitted, and features a rounded-edge profile with a built-in gasket that sits flush against the wall surface.

Intended for residential and commercial installation where a dimmer switch is needed, the plate supports a range of dimmer module types including trailing-edge LED dimmers, leading-edge incandescent dimmers, and rotary dimmers depending on the module chosen. The unpopulated design allows the installer to select the exact dimmer mechanism required for the lamp or fixture being controlled, rather than pre-specifying dimmer technology at the plate stage.

The matt black finish is applied to premium-grade steel, giving a low-sheen surface that resists fingerprints and suits modern, industrial and monochrome interior schemes. The metal dimmer cap matches the plate finish, maintaining a cohesive appearance across the control surface. The IP20 rating restricts use to dry indoor areas — bedrooms, living rooms, hallways and offices where no direct water contact occurs.

Frequently Asked

What dimmer module does this plate require?

The plate is unpopulated and sold without a dimmer module. You need to purchase a separate Knightsbridge dimmer module — either centre-mounted or offset — that matches your lamp type (LED, incandescent, halogen). The module clips or screws into the back of the plate.

Can this be used with LED bulbs?

Yes, provided you fit a trailing-edge LED-compatible dimmer module behind the plate. Standard rotary dimmers designed for incandescent lamps often cause flicker or poor dimming range with LEDs, so module selection matters.

What back box depth is needed?

Knightsbridge dimmer modules typically require a 25mm minimum back box depth, though deeper boxes (35mm) provide more space for cable management. Check the specific module datasheet before installation.

Is the rounded edge screwless?

No. The image shows two screw fixings visible on the faceplate. The rounded edge refers to the profile of the plate perimeter, not the fixing method. Knightsbridge's screwless ranges use a different cover-plate system.
