Fan Isolator Switches – 3 Pole Extractor Fan Isolators

A fan isolator switch lets you safely cut all power to a bathroom or kitchen extractor fan, including the timer feed, for cleaning or maintenance. Every fan isolator switch in our range is a 10A triple pole (3 pole) design, from BG, Click Deco and Knightsbridge, in finishes to match your other switches.

Why Extractor Fans Need a 3 Pole Fan Isolator

Most extractor fans with an overrun timer have two live feeds: a permanent live and a switched live from the light. A standard switch only cuts one of them. A 3 pole fan isolator switch disconnects the permanent live, the switched live and the neutral together, so the fan can be worked on safely.

• 10A / 10AX triple pole isolation
• Isolates the permanent live, switched live and neutral
• Fits a standard one-gang back box (16mm minimum on most models)
• Usually fitted outside the bathroom, next to the door
