20AX Intermediate Module - Black Nickel

Description

Description
The Knightsbridge 20AX intermediate module is a single-gang grid component rated at 20A, designed to control lighting circuits from three or more switching positions. The module

features a black nickel rocker switch set in a white ABS and steel housing that clips into Knightsbridge grid mounting frames (sold separately) from the front, allowing modules to be added or removed without disturbing the back box wiring.

Intermediate switching is used when a lighting circuit needs control from more than two locations — typically staircases with landings, long hallways with entry points at both ends and a midpoint, or large open-plan spaces where light control is needed from multiple doorways. The intermediate module sits between two two-way switches in the circuit, passing the switched live connection through regardless of rocker position. The 20A rating handles high-load lighting circuits including banks of downlights or large chandeliers.

The module measures 56.3mm high by 24.8mm wide and requires a minimum 35mm back box depth when installed in a grid frame. The black nickel finish provides a dark gunmetal appearance that sits between polished chrome and matt black, pairing with both warm and cool-toned interiors. The rocker projects 7mm from the face of the grid frame once clipped in, giving tactile feedback when operated.

Frequently Asked
What is an intermediate module used for?

An intermediate module allows lighting to be controlled from three or more switching positions. It sits between two two-way switches in the circuit. Common applications include staircases with landings, long hallways with multiple entry points, and large rooms where light control is needed from more than two locations.

What grid frame does this fit?

The module clips into Knightsbridge grid mounting frames (sold separately). Grid frames are available in 1-gang, 2-gang, 3-gang and 4-gang configurations, allowing multiple modules to be grouped in a single plate. The frame is fixed to the back box first, then modules clip in from the front.

Can this be paired with dimmer modules?

No. Intermediate switching is incompatible with standard dimmer circuits. If dimming is required in a multi-way switching setup, you need a specific multi-way dimmer system designed for that purpose — contact us for recommendations.

What other finishes are available?

Knightsbridge produces grid modules in a wide range of finishes including polished chrome, brushed chrome, polished brass, matt black and white. Use the search function or category filters to find other finishes in stock at Niori.
