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?

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




    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.




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