Description

The Knightsbridge 20AX DP key switch module is a single-width grid module marked 'EMG LTG TEST' on the faceplate, with a rotating key-operated switch controlling a double-pole 20AX circuit. 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.

Designed 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.

The 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.

Frequently Asked

What grid frame does this fit into?

The module clips into Knightsbridge grid mounting frames sold separately. The 24.8mm width is a single grid module, so it fits one position in a multi-gang grid frame. The frame must be fitted to a back box with at least 35mm depth.

What is the key switch used for?

The key-operated switch is designed for testing emergency lighting circuits. 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. This allows compliance with BS 5266 testing requirements.

Is the key removable in both positions?

Typically yes, but check the datasheet. Most Knightsbridge key switches allow the key to be removed in either the 'top' or 'test' position, preventing unauthorized switching while the key is held by facilities management.

What other finishes are available?

Knightsbridge produces grid modules in a range of finishes including polished chrome, brushed chrome, white, black nickel and stainless steel. Use the search function or contact us to check availability of this specific module in other finishes.
