FAQs
Can I install this switch myself?
Electrical work should only be performed by a qualified electrician to ensure safety and compliance with building regulations.
Why is a 3-pole switch necessary?
A 3-pole switch isolates all three supply lines (live, neutral, and earth/switch-live), which is the safest method for disconnecting ventilation equipment.
Is this switch suitable for damp environments?
While the switch is designed for bathroom environments, it should be installed outside the bathroom zone or in a location where it will not be subject to direct water spray.
What is the maximum current rating?
The switch is rated for 10AX, which is sufficient for standard residential ventilation fans.
Does it come with a back box?
No, this is a switch faceplate; you will need to ensure a compatible back box is installed in the wall.
Troubleshooting
Switch does not isolate the fan power
Verify that the wiring is correctly connected to the appropriate terminal poles and that the supply is live.
Switch feels loose in the back box
Check that the fixing screws are tightened properly to the mounting lugs; if the box is recessed too far, use spacer plates.

Setup, Compatibility & Care
Installation must be performed by a competent person in accordance with current IET Wiring Regulations. Ensure the power is isolated at the consumer unit before beginning any work. The switch fits into standard back boxes, but check that your existing box has sufficient depth for the switch mechanism and wiring connections. For maintenance, keep the polished chrome surface clean by wiping it gently with a soft, dry cloth. Avoid using abrasive chemical cleaners or scouring pads, as these will scratch the high-gloss finish.
