Description
The Knightsbridge 10AX 1-gang intermediate switch is a three-way lighting control in a matt black rounded-edge metal plate. It sits between two 2-way switches in a circuit, allowing a single light to be controlled from three separate locations — typically at the bottom of a staircase, on a mid-floor landing, and at the top of the stairs.
Designed for residential staircases, long hallways, and open-plan spaces where lighting needs to be controlled from more than two points, the switch carries a 10AX rating suitable for up to 2,300W of lighting load on 230V mains. The premium-grade steel faceplate measures 87.75mm square with a projection of 7.5mm from the wall once fitted to a standard 16mm minimum back box. The rounded edges soften the profile against walls and reduce the risk of snagging on clothing or bags in narrow hallways.
The matt black finish is a low-sheen powder coat over the steel substrate, giving a fingerprint-resistant surface that pairs well with industrial, contemporary and minimalist interiors. The metal rocker matches the faceplate tone exactly, avoiding the tonal mismatch that can occur with plastic inserts behind metal plates. The switch includes screw terminals for standard UK wiring, an earth terminal for Class I installation, and a built-in gasket behind the plate that improves the IP20 rating by reducing dust ingress around the edges.

Frequently Asked
What is an intermediate switch used for?
An intermediate switch sits between two 2-way switches in a three-way lighting circuit, allowing a single light or group of lights to be controlled from three or more separate locations. Common installations include staircases with a landing, long hallways with three entry points, and large rooms with multiple doorways.
What back box depth is required?
A minimum 16mm mounting box depth is needed. The switch plate itself projects 7.5mm from the wall once fitted, giving a total depth of approximately 23.5mm from the wall surface to the back of the box.
Is the plate screwed to the wall?
Yes. The Knightsbridge rounded-edge range uses visible screw fixings at the top and bottom of the plate. The screws are finished to match the matt black faceplate. For a screwless option, see the Knightsbridge screwless range.
What other finishes are available?
Knightsbridge produces the rounded-edge intermediate switch in multiple finishes including polished chrome, brushed chrome, polished brass, antique brass, and white. Use the search function or filters at Niori to find other variants in stock.
