4 Gang Dimmer Plate With Matching Dimmer Caps - White Square Edge

The Knightsbridge SN4DIM is a 4-gang dimmer plate in white thermoset resin, supplied unpopulated with four matching dimmer caps and screw cap covers. The plate accepts Knightsbridge modular dimmer modules or compatible third-party dimmer modules, allowing installers to build a custom dimming solution to match the specific load requirements of each circuit.

Designed for residential and light commercial installation where multiple lighting circuits need independent dimming control from a single wall position, the plate suits living rooms with separate ceiling, wall and accent lighting circuits, or hotel rooms and serviced apartments where bedside, desk and overhead lighting are controlled from one panel. The 146mm width fits a standard 2-gang back box with a 4-gang plate conversion spacer.

The thermoset resin construction resists impact, heat and discolouration better than standard thermoplastic plates, and carries anti-microbial properties tested to ISO 22196:2011, reducing bacterial growth on high-touch surfaces in healthcare, hospitality and residential settings. The 9mm square-edge profile sits flush to the wall with visible fixing screws concealed under snap-on caps once installation is complete. The plate carries a 25-year warranty.

Product Specification Sheet

What dimmer modules does this plate accept?

The plate accepts Knightsbridge modular dimmer modules and most compatible third-party modular dimmers designed for UK standard plates. The plate is supplied unpopulated, so dimmer modules must be purchased separately and fitted by a qualified electrician to match the specific load type and wattage of each circuit.

What back box is required?

A standard 2-gang 25mm back box with a 4-gang conversion spacer is required. The 146mm plate width spans the same horizontal distance as a standard 2-gang plate, but the conversion spacer provides the additional mounting points for four modules.

What does the anti-microbial property do?

The thermoset resin is treated to reduce bacterial growth on the surface of the plate, tested to ISO 22196:2011. This is useful in healthcare settings, care homes, hospitality and high-traffic residential areas where switches are touched frequently and hygiene is a priority.

Are screw caps included?

Yes. The plate includes snap-on screw caps that hide the fixing screws once the plate is mounted, giving a cleaner finish than visible screwheads on the faceplate.
