Description
The Knightsbridge 10AX 1-gang intermediate switch features a gunmetal-finished steel faceplate with a matching metal rocker, set on an ultra-flat plate that projects just 2.5mm from the wall. Rated at 10AX on 230V mains, the switch handles lighting circuits up to 2,300W and is designed specifically for three-way switching installations where a light is controlled from three or more points.
Intermediate switches sit between two two-way switches in extended circuits, typically found on staircases with landings, long hallways with switches at both ends and a midpoint, or open-plan spaces where a single lighting zone needs control from multiple doorways. The 16mm minimum back box depth requirement makes the switch compatible with standard UK metal or plastic mounting boxes, and the built-in gasket provides moisture protection at the faceplate edge.
The gunmetal finish is a brushed dark grey metal with a subtle grain that softens reflections and fingerprints compared to polished chrome or stainless steel. The flat plate design eliminates the raised edge found on traditional UK switches, sitting nearly flush with the wall surface. Certified to EN 60669-1 and carrying a 25-year warranty, the switch uses premium-grade steel construction throughout the faceplate and rocker mechanism.

Frequently Asked
When do I need an intermediate switch?
An intermediate switch is used in three-way or four-way lighting circuits where a single light or lighting zone needs to be controlled from three or more locations. A typical setup uses two two-way switches at the start and end of the circuit, with one or more intermediate switches in between. Common applications include staircases with top, landing, and bottom switches, or long hallways with switches at each end and a midpoint.
What back box depth is required?
A 16mm minimum mounting box depth is needed. The ultra-flat plate adds just 2.5mm of projection from the wall surface once installed, making this one of the lowest-profile switches available in the Knightsbridge range.
What's the difference between gunmetal and brushed chrome?
Gunmetal is a darker, warmer grey metal finish with a subtle grain, while brushed chrome is a cooler, lighter silver-grey. Gunmetal pairs well with industrial, contemporary and warm-toned interiors, while brushed chrome suits cooler modern schemes.
Can this switch be used with LED lighting?
Yes. The 10AX rating handles both traditional incandescent and modern LED lighting circuits up to 2,300W total load. Most LED installations run well below this threshold.
