Description
The Knightsbridge GDM022BN is a 6A 1-gang 2-way dummy dimmer module with a black nickel finish, designed for modular grid systems. It provides the visual appearance of a rotary dimmer control while functioning as a standard on/off switch with 2-way capability, allowing control of the same lighting circuit from two separate locations.
This module suits installations where consistency of appearance across a grid faceplate matters more than dimming capability — typically in commercial settings, hotel rooms, or residential rooms where some circuits need dimming and others just need switching, but all controls should look identical. The push-on/push-off rotary knob operates the internal switch mechanism without varying the voltage output, so it controls non-dimmable LED circuits, fluorescent fittings, or low-voltage transformers without the compatibility issues that actual dimmers can introduce.
The module measures 25mm wide (single-gang grid width) and requires a minimum 35mm back box depth for installation. The black nickel finish provides a dark metallic surface that sits between polished chrome and matt black, pairing well with contemporary and industrial interiors. The module clips into standard Knightsbridge grid frames and can be combined with other grid modules (sockets, data points, switched outlets) to build custom control panels tailored to specific room layouts.

Frequently Asked
Does this module actually dim lights?
No. Despite the rotary knob appearance, this is a standard on/off switch with 2-way capability. It does not vary voltage and cannot dim lights. It exists to match the appearance of actual dimmer modules in the same grid system.
What is 2-way switching?
2-way switching allows the same light to be controlled from two separate switch locations — typically at opposite ends of a hallway or at the top and bottom of a staircase. This module can be wired as part of a 2-way circuit.
What grid system does this fit?
This module fits Knightsbridge's modular grid system. It clips into grid frames (sold separately) that accommodate 1, 2, 3 or 4 modules depending on the faceplate size chosen. The module width is 25mm, equivalent to one grid position.
What other finishes are available?
Knightsbridge produces dummy dimmer modules across their full finish range including polished chrome, brushed chrome, polished brass, antique brass, matt black and white. Use the search or filter functions to find other variants in stock at Niori.
