20AX 2-Way Grid Module Centre Off - Matt Black

The Knightsbridge 20AX 2-way grid module is a single-pole switch unit with a centre-off position that allows control of two separate circuits from a single rocker. The centre-off position isolates both circuits simultaneously, which is useful for controlling independent lighting zones, motorised blinds, or any application where three switching states (circuit A, off, circuit B) are needed from one module.

Designed for use within Knightsbridge's modular grid system, the module clips into separately-sold mounting frames from the front without requiring screws or tools, allowing switches to be configured in custom layouts (1-gang, 2-gang, 3-gang or more) depending on the frame chosen. This makes grid modules popular in commercial fit-outs, hospitality projects and residential installations where a consistent aesthetic across multiple switch types is required. The module fits a standard 35mm minimum back box depth.

The matt black rocker and white surround provide clear visual contrast for the switch position, and the ABS and steel construction gives the module a rated lifespan backed by Knightsbridge's 25-year warranty. The 20AX rating handles loads up to 4,600W on 230V circuits, making it suitable for high-draw appliances, multiple lighting circuits or motorised equipment beyond the capacity of standard 10AX modules.

Product Specification Sheet

What is a centre-off switch position?

The centre-off position means the rocker has three states: up (circuit A on), centre (both circuits off), down (circuit B on). This allows control of two independent circuits from a single module, useful for controlling separate lighting zones or motorised equipment like blinds and curtains.

What mounting frame does this module require?

The module clips into Knightsbridge modular grid frames, sold separately. Frames are available in 1-gang, 2-gang, 3-gang and larger configurations, and in various finishes to match the matt black module. The frame mounts to a standard 35mm back box.

What load can a 20AX module handle?

The 20AX rating allows the module to switch loads up to 4,600W on 230V circuits. This is higher than standard 10AX (2,300W) modules, making it suitable for high-draw appliances, multiple lighting circuits, or motorised equipment.

Can this module be used with dimmer circuits?

No. This is a standard on/off switch module and does not provide dimming control. For dimming, a separate dimmer module from the Knightsbridge grid range is required.
