Description

The Knightsbridge 10AX fan isolator switch provides triple-pole isolation for extractor fans behind a brushed chrome flat plate with a matching metal rocker. The 2.5mm projection from the wall gives a near-flush finish once fitted, and the 87.5mm square faceplate fits standard single-gang back boxes with a minimum 16mm depth.

Designed for bathrooms, kitchens, utility rooms and commercial washrooms where extractor fans require a visible and accessible isolator, the switch breaks all three poles (live, neutral and switched live) when turned off, providing full circuit isolation for safe maintenance. The built-in gasket behind the faceplate improves dust and moisture resistance to IP20, and the metal rocker gives tactile feedback on the switch position.

The brushed chrome finish shows a linear grain texture that hides fingerprints and minor surface marks better than polished chrome, making it practical for high-traffic areas where the switch is regularly operated. The 10AX rating handles loads up to 2,300W on 230V mains, covering typical residential extractor fans rated between 5W and 35W with margin for larger commercial ventilation units.

Certified to EN 60669-1 (general switch requirements) and EN 60669-2-4 (isolating switches), the switch carries a 25-year warranty from Knightsbridge. The premium-grade steel construction resists flexing during installation and maintains contact pressure over time.

Frequently Asked

What does triple-pole isolation mean?

A triple-pole isolator breaks all three conductors in the circuit when switched off: live, neutral and switched live. This provides complete electrical isolation, which is required by wiring regulations for accessible maintenance of fixed appliances like extractor fans.

What back box depth is needed?

The switch requires a minimum 16mm back box depth. The flat plate design allows installation in shallow-depth back boxes where space behind the wall is limited, such as dot-and-dab plasterboard over masonry.

Can this be used in a bathroom?

Yes, provided it is installed outside the designated bathroom zones (typically Zone 0, 1 and 2). The IP20 rating means the switch is not splash-proof, so it must be positioned where direct water contact cannot occur. Most bathrooms position the fan isolator switch outside the bathroom door or on a wall outside the shower enclosure area.

What fan load can it handle?

The 10AX rating handles up to 2,300W at 230V. Typical domestic extractor fans draw between 5W and 35W, so the switch has substantial capacity margin. Larger commercial ventilation units rated up to 500W are also within the switch's capability.
