20AX 2 Way Retractive Switch Module Centre Off - White Grid

The Knightsbridge 20AX 2-way retractive switch module provides dual circuit control with a centre-off neutral position, built for installation in Knightsbridge Curved Grid systems. The module is rated at 20AX on 230V 50Hz mains, allowing it to handle lighting circuits, automation control or other high-demand switching applications where two separate circuits need to be controlled from a single switch position.

Designed for use in custom grid switch plates, the module clips into compatible Knightsbridge grid frames that accept 25mm-wide modules. The retractive action means the rocker returns to the centre-off position when released, rather than latching in the up or down position like a standard switch. This behaviour suits applications where momentary contact is needed to trigger relay-driven or automation-controlled circuits, or where the centre-off state acts as a safety interlock between two circuits.

The module measures 55mm high by 25mm wide, occupying one standard grid module space. The white thermoset resin construction includes anti-microbial properties tested to ISO 22196:2011, making the module suitable for healthcare, hospitality and high-traffic residential environments where surface hygiene matters. Installation requires a minimum 35mm back box depth, with the module recessing 20mm into the wall and projecting 8mm from the grid plate once fitted.

The front-mounted design allows the module to be clipped in and removed from the grid frame without disturbing rear terminations, simplifying maintenance and grid plate reconfiguration. Knightsbridge backs this module with a 25-year warranty, reflecting the commercial-grade build quality and long service life expected from their grid component range.

Product Specification Sheet

Product Manual

What is a retractive switch and how does it differ from a standard switch?

A retractive switch returns to the centre-off position when you release it, rather than staying latched in the up or down position. This makes it suitable for momentary-contact applications like controlling relays, automation systems, or triggering events rather than directly switching a load on permanently.

What grid system is this module compatible with?

The module is designed exclusively for Knightsbridge Curved Grid systems. It clips into grid frames that accept 25mm-wide modules and will not fit other manufacturers' grid systems or standard switch back boxes without a compatible grid frame.

What does the 20AX rating mean?

20AX means the switch is rated for 20 amps on 230V AC supply, suitable for controlling high-load circuits like large lighting arrays, heating controls or motor-driven equipment. The 'X' denotes the switch meets specific contact performance standards for reliability under frequent switching.

What back box depth is required?

A minimum 35mm back box depth is needed. The module itself recesses 20mm into the wall once fitted into the grid frame, with the grid plate and switch rocker adding approximately 8mm of projection from the finished wall surface.
