The double pole design isolates both live and neutral lines when switched off, providing additional safety for high-draw permanent installations. A red neon indicator at the top of the plate illuminates when the switch is on.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential bathroom and utility room installations where the appliance has no plug or separate isolation point, the switch fits a standard 25mm back box and is wired via screw terminals at the rear. The square edge plate includes a built-in gasket that sits flush against the wall, reducing dust and moisture ingress. The rocker is colour-matched to the brushed chrome plate rather than being white plastic.\u003c\/p\u003e\n\u003cp\u003eThe brushed chrome finish is a directional brushed steel effect with a low-sheen metallic surface that resists fingerprints better than polished chrome. The 89mm square plate is certified to EN 60669-1 and carries a 25-year warranty. The neon indicator draws negligible power and helps confirm at a glance whether an immersion heater or similar appliance has been left on.\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\u003e89 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e89 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e10.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
