Extract Fan isolator with neon light

Wolfs

Hi, my bathroom extract fan has an isolator switch mounted above the door outside the room. It is two speed controlled via the button on the light switch. I & others sometimes forget to switch it off when not in use, so I want to fit a switch with a neon light.
I can't find such a switch online or in shops.

Does anyone know (i) where I can buy a switch with a neon, or (ii) is it ok to fit a normal fused spur switch with neon. If yes, can you send a link to a suitable switch please.
I have attached photos of the isolator and the fan unit.

Thanks in advance.

the isolator can be swapped for a fused spur w/neon anyhow


fused spur may be better than DP switch

some fans state that they should have individual fused protection rather than the lighting breaker

something not quite right about the wiring of that isolator
missing a wire or two
can you post a better picture with the back/terminals visable

the isolator should switch
1 neutral
2 permanent live
3 switched live

your pic seems to show only 2 of these
also the fan shows 2 blue wires and 1 brown
this should be 2 brown and 1 blue

its possible that the switched live or permanent live has been wired by a blue cable in error
either way the isolator is not functioning correctly

don't see a prob

seems to be just 2 pole switching-no overrun



fan though seems to have blue wiring for phase/line

would appear the fan has feed/switch feed/neutral connections
therefore all 3 poles should be isolated

don't think so

DP isolation and then 2-way switching for speed control-no overrun


dunno why they're using blue for high/low though?

Hi, thanks for all the replies so far.
I've posted extra pics as requested (hope these show what you asked for).
There is no overrun on the fan as far as I know. It's simple on/of with the isolator and the speed can be switched high/low via the switch for the lights.

Thanks.

Think you may be on to something here guys. I checked the isolator on the other bathroom after reading your posts. Pics attached. Clearly different wiring to the other bathroom!! Both fans are the same and operate the same, ie on/off via isolator and high/low via switch at light switch (no overrun). Suggestions welcome!

no

but your setup is slightly odd in that you're using the isolating switches to control the fan instead of isolation only

colours not right either

but you can fit a DP switch or spur w/neon

on-off> 2-way speed-control > 3-pole isolation

is prob the way it should be done
