A standard light switch breaks only the live wire, but a \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003e3 pole isolator\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e disconnects live, neutral, and the permanent live (often used for fan overrun timers). This ensures the fan is completely isolated from all electrical supplies – essential for safe cleaning, maintenance, or replacement. The switch allows you to turn off the fan without affecting the room lighting, and its 10A rating is more than sufficient for domestic extractor fans. Finished in warm, brushed satin brass, this isolator switch blends safety requirements with sophisticated design.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eMeasuring H:86mm x W:86mm, this compact unit fits a standard single gang back box – and remarkably, it fits a \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003e25mm shallow box\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e, making it ideal for retrofit projects where wall depth is limited. The screwless clip-on faceplate creates a flush, seamless look, while the satin brass finish resists moisture-related tarnishing better than many metals (though it should not be installed inside a shower enclosure). Whether you are fitting a new bathroom, upgrading a kitchen extractor, or simply replacing a worn white plastic isolator, this Evolve switch offers compliance, convenience, and contemporary style.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eWhy Choose This Evolve 3 Pole Fan Isolator Switch?\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eChoosing this Evolve fan isolator means you can finally replace that cheap, yellowing plastic switch on your bathroom wall with a premium satin brass finish that matches the rest of your Evolve accessories. The 3 pole switching is not a luxury – it is a \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003erequirement of UK wiring regulations (BS 7671)\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e for extractor fans with timer overrun functions, ensuring the fan can be fully isolated for maintenance without cutting power to the lighting circuit. The ability to fit a 25mm back box is a huge advantage in solid walls or tiled bathrooms where deeper boxes are difficult to install. For homeowners, landlords, or electricians who insist on both regulatory compliance and beautiful design, this isolator switch is the perfect, discreet
