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.\u003c\/p\u003e\n\u003cp\u003eDesigned 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e56.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e24.8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e2.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e17.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.

The key can be removed in either the on or off position, depending on how the installer configures security.
