Description
The Knightsbridge 10AX 1-gang intermediate switch features a square edge antique brass plate with a matching metal rocker, designed for three-way lighting circuits where a single light is controlled from three separate switch positions. The intermediate function sits between two two-way switches, typically on staircases with landings or in hallways with three access points.
Built from premium-grade steel with an antique brass finish, the switch provides a warm, aged metallic tone that suits period properties, traditional interiors and vintage-inspired schemes. The square edge profile gives a defined geometric outline against the wall, distinct from rounded-edge contemporary styles. The metal rocker matches the plate finish, creating a unified appearance across the switch face.
The 10AX rating handles loads up to 2,300W on a 230V circuit, suitable for standard domestic lighting including LED, halogen and incandescent bulbs. The switch requires a minimum 16mm back box depth for installation and includes an earth terminal for metal back box bonding. A built-in gasket provides moisture resistance to IP20 standard, making it suitable for dry indoor locations. The screw terminals accept standard UK wiring.

Frequently Asked
What is an intermediate switch used for?
An intermediate switch controls a single light from three or more locations. It sits between two two-way switches in the circuit, typically on staircases with upper and lower landings or in long hallways with three access points. You cannot use an intermediate switch alone — it only functions when wired between two-way switches.
What back box depth is required?
A minimum 16mm back box depth is needed for safe installation. The switch plate adds 10.5mm of projection from the wall once fitted.
Is the antique brass finish lacquered?
Most Knightsbridge antique brass finishes are lightly lacquered to slow natural tarnishing. The finish will develop additional patina over time if the lacquer wears in high-contact areas around the rocker. This is a characteristic of antique brass rather than a defect.
What other finishes are available in this range?
Knightsbridge produces this square edge style in multiple finishes including polished brass, brushed brass, polished chrome, brushed chrome, matt black and white. Use the search function or filters to find other variants in stock at Niori.
