20A 1 Gang DP Switch Neon - Black Nickel Screwless

The Knightsbridge 20A 1-gang double pole switch with neon indicator features a black nickel screwless faceplate and a contrasting chrome rocker. The 20A rating handles fixed high-power appliances such as immersion heaters, electric showers and water heaters, while the double pole switching isolates both live and neutral lines when turned off.

Designed for kitchens, utility rooms and bathrooms (outside zones 0-2), the switch mounts in a standard 25mm minimum back box depth. The neon indicator glows red when the switch is in the on position, providing a visible status check from across the room without needing to inspect the rocker position. The screwless cover plate clips onto a separate metal sub-frame, leaving no visible fixings on the wall once installed.

The black nickel finish is a dark gunmetal tone that sits between brushed nickel and matt black, providing a neutral metallic accent that pairs with both warm and cool-toned interiors. The premium-grade steel construction gives the faceplate rigidity and a low 4.3mm projection from the wall. The rocker sits within a black surround that frames the chrome actuator and gives definition to the switch aperture. The built-in gasket behind the faceplate prevents paint bleed during redecoration.

Product Manual

What appliances is this switch suitable for?

The 20A rating makes it suitable for high-power fixed appliances such as immersion heaters, electric showers, water heaters and towel radiators. It is not intended for general lighting circuits or plug sockets.

What does the neon indicator show?

The neon glows red when the switch is in the on position, providing a visual status check. This is useful for confirming whether an immersion heater or water heater is currently powered without needing to check the appliance itself.

Can it be used in bathrooms?

The IP20 rating means the switch is suitable for dry indoor use only. In bathrooms it must be installed outside zones 0, 1 and 2 (typically 3m+ from the bath or shower enclosure). For zones 1 and 2, a switch with a higher IP rating is required.
