Description

The Knightsbridge 20AX key switch module is a 2-way single pole switch designed for emergency lighting test circuits, marked 'EMG LTG TEST' on the anthracite faceplate. The module clips into Knightsbridge modular grid mounting frames from the front, requiring a minimum 35mm back box depth behind the frame. A removable key controls the switch operation, restricting access to authorised personnel.

Designed for commercial buildings, offices, retail premises and public buildings where emergency lighting requires periodic testing under Building Regulations, the key switch allows maintenance teams to test emergency lighting circuits without accessing the main distribution board. The 20AX rating handles lighting loads up to 4,600W on 230V circuits, suitable for testing multiple emergency fittings on a single circuit.

The module body is ABS with steel internal components, finished in anthracite grey to match Knightsbridge's grid range. The 2-way switching configuration allows the module to be wired in series with other switches or used as a standalone test isolator. The IP20 rating suits standard indoor dry environments. The supplied key can be removed in either the on or off position, depending on how security and normal operation are configured during installation.

Frequently Asked

What is this module used for?

The key switch module controls emergency lighting test circuits, allowing authorised personnel to test emergency fittings without accessing the main electrical panel. This is required under UK Building Regulations for periodic emergency lighting testing in commercial premises.

What mounting frame does it require?

The module clips into Knightsbridge modular grid mounting frames, sold separately. The frame determines how many modules can be fitted side-by-side in a single faceplate. A 35mm minimum back box depth is required behind the frame.

Can the key be removed when the switch is on?

Yes. The key can be removed in either the on or off position, depending on how the installer configures security. Typically the key is removed when the switch is in the 'normal' position, forcing users to have the key to activate the test mode.

What does the 20AX rating mean?

20AX means the switch is rated for 20 amps on inductive loads (such as lighting circuits with multiple fittings). On a 230V circuit this equals approximately 4,600W capacity, enough to test multiple emergency lights on a single circuit.
