Extractor Fan Switch.

Zoomup
I have just stumbled upon this. A fan isolator switch with integral fuse. Has anybody any experiences with these please. Any good?

    No direct experience, but I expect that it would be fine.

    The switch sees only infrequent use, for maintenance, so even a very cheap switch should last decades.

    The load is minimal at a fraction of an amp so even a poor quality fuse holder, switch, and terminals would be fine.


    If used many times a day for functional switching and loaded to a full 13 amps, I would be doubtful, but for a small fan it should be fine.

    I wonder which of the 3 poles is fused ?

    In some ways you'd need 2, as there is a fixed live and a switched live (trigger signal)

    They are made by Click accessories, Clickmode modules which can be either purchased built-up as a complete unit, or you just buy the individual modules, 3 pole fan switch, fuseholder, front plate and rear gridplate and assemble yourself. They are great because it saves you having to chop 2 x backboxes into the wall.

    I generally take the live feed for the whole bathroom through the fuse, that way all fan and light supplies/switch wires are protected by the fuse as per "manufacturers instructions"

    The price for that item linked to is outrageous - the individual modules can be purchased for a pound or so each.

    Doesn't the item listing circuit diagram show the fuse in the supply so covering both?

    Then why would you need a three pole switch?

    3 pole switch required in order to isolate the fan/SELV transformer etc.

    So that you may isolate the fan separately from the lighting. Oh, I nearly forgot: 'cos the manufacturer says so. I must say, though, that the fuse seems unnecessary.

    But if, as stated by perspicacious, the fuse covers both the permanent live and switched live then a three-pole switch is not necessary; a switched double-pole FCU would suffice.

    Or just use fans with built in fuses and a normal fan isolator. It’s really pointless with B6 MCB at the board but what do I know.

    The idea of the fan isolator was to keep the lights on when servicing the fan.
