20AX 2 Way Retractive SP Switch Module - Polished Chrome

The Knightsbridge 20AX 2-way retractive switch module is a single-pole grid component designed to clip into Knightsbridge grid mounting frames from the front without needing rear access to the back box. The module carries a 20AX rating at 230V, making it suitable for controlling lighting circuits, extractor fans, and other switched loads up to approximately 4,600W. The polished chrome finish provides a reflective metallic surface that pairs with traditional and contemporary grid installations.

Retractive operation means the rocker returns to the central off position after being pressed, making this module suitable for two-way lighting control where the switch only momentarily makes contact rather than staying latched in an on or off state. The module is marked PRESS on the rocker face to indicate the retractive action to end users. It fits Knightsbridge's modular grid system, which allows multiple switch, socket, and blanking modules to be combined in a single faceplate.

The module measures 56.3mm high by 24.8mm wide and projects 7mm from the front of the mounting frame once clipped in. The recessed depth behind the frame is 18.7mm, requiring a minimum 35mm back box depth for safe installation. The construction uses ABS plastic for the body and steel contact mechanisms, providing corrosion resistance and mechanical durability. The IP20 rating confirms suitability for dry indoor environments only.

Product Specification Sheet

What does retractive mean?

A retractive switch returns to the central off position after being pressed, unlike a latching switch that stays in the on or off position. Retractive switches are used in two-way lighting circuits where the switch only needs to momentarily make contact to toggle the circuit state.

What mounting frame does this module require?

The module clips into Knightsbridge's modular grid mounting frames, which are sold separately. The frames are available in various gang configurations (1-gang, 2-gang, 3-gang) and finishes to match the module. The module clips in from the front of the frame without rear access.

What load can a 20AX switch handle?

A 20AX rating at 230V allows the module to switch loads up to approximately 4,600W. This covers typical lighting circuits, extractor fans, and similar switched loads in residential and commercial installations.

Can this be used in bathrooms?

The IP20 rating means the module is suitable for dry indoor environments only. It cannot be used in zones 1 or 2 of a bathroom where water spray or splashing is present. For bathroom switching, consider IP-rated alternatives or install the switch outside the regulated zones.
