20AX Intermediate Grid Toggle Switch Module - Matt Black

The Knightsbridge 20AX intermediate grid toggle module is a single-gang switch component designed for multi-way lighting circuits controlled from three or more locations. Rated at 20 amps, the module handles loads up to 4,600W on 230V mains and features a traditional toggle action with a matt black finish. The module clips into Knightsbridge grid mounting frames from the front without requiring rear access to the back box.

Intermediate switches sit between two-way switches in circuits where a single light or group of lights needs control from more than two positions — common in long corridors, staircases with landings at both ends, and large rooms with multiple entry points. The grid format allows multiple switch modules to be combined into a single faceplate, reducing the number of back boxes needed and giving a cleaner finish than individual switch plates side by side.

The module body is constructed from steel and ABS thermoplastic, giving structural rigidity and electrical insulation. The matt black finish provides a neutral appearance that pairs with contemporary, industrial and monochrome schemes. The IP20 rating limits the module to dry indoor locations — it is not suitable for bathrooms, outdoor use or any zone where water contact is possible. The 35mm minimum back box depth accommodates standard UK grid frames.
