The double pole switching isolates both live and neutral lines when the switch is turned off, a requirement for certain fixed appliances including immersion heaters, electric ovens and some water heating systems.\u003c\/p\u003e\n\u003cp\u003eThe neon indicator glows red when the switch is in the on position, providing visual confirmation that power is flowing to the appliance. This is useful for appliances located in a different room or where the appliance itself has no visible power indicator. The switch is designed for controlling single fixed appliances rather than multiple outlets, with the 20A rating handling higher loads than standard 13A socket circuits.\u003c\/p\u003e\n\u003cp\u003eThe screwless cover plate clips onto a separate metal sub-frame fixed to the back box, leaving no visible screws or fixings once installed. The polished brass finish gives a warm metallic accent that pairs well with traditional, classical and warm-toned contemporary interiors. The switch requires a 25mm minimum back box depth and projects just 4.3mm from the wall once fitted, sitting flush with most plasterwork and tiling.\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\u003e87.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e87.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e4.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
