The module clips into position from the front of Knightsbridge grid mounting frames (sold separately), allowing installation without removing the frame from the wall. The key is supplied with the module.\u003c\/p\u003e\n\u003cp\u003eDesigned for emergency lighting circuits, the key switch allows authorized personnel to test emergency lighting systems without accessing a locked electrical cupboard or main distribution board. The double-pole switching isolates both live and neutral lines when turned to the test position, providing controlled circuit interruption for periodic testing as required by BS 5266 and workplace fire safety regulations. The 20AX rating handles circuits up to 4,600W on 230V supply.\u003c\/p\u003e\n\u003cp\u003eThe matt black ABS faceplate with moulded white text provides clear labelling visible in service cupboards, plant rooms, and commercial installations. The module measures 24.8mm wide (single grid width) and requires a minimum 35mm back box depth when fitted into a grid frame. The steel internal mechanism and ABS housing are rated IP20 for dry indoor locations. Knightsbridge grid modules carry a 25-year warranty.\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 24.8mm width is a single grid module, so it fits one position in a multi-gang grid frame.

Turning the key to the test position interrupts the mains supply to emergency lights, forcing them to run on battery backup to verify they work during a power cut.
