This is a simple 3 pole isolator, this enables you to work on the fan by isolating the live, the switched live and the neutral
It should be a simple swap
Remember to isolate safely at the consumer unit
thank you Andrew. I was really after the wiring diagram that shows the wiring - eg L to L and/or L1, N to N etc. The photo is the switch that we have. The 2 reds are the live, the 2 blues the neutral, so is the switched live the 2 yellow ones? No problem isolating the consumer unit.
Yes, switched live is yellow
It is straight forward - in the feed side you will have a red, yellow and blue and in the opposite connections you will have a red, yellow and blue - with the earths together in the brass connection in the back box
Straight through the switch in line
Hello again. So, sorry to labour the point ....at the top of the switch we have L1 L2 and N; red into L1, yellow into L2 and blue into N; then at the bottom the same again. does it matter from which of the 2 bound cables each set of 3 wires comes from when going into the top and out of the bottom as I can't see any difference between the 2? thanks again.
No it does not matter, the switch just links them together and you use this as an isolator when working on the fan
It would only matter if it had a fuse in it
Many thanks. I'm scheduled to get the work done on thursday so if it's fine by you I'll close off this query after that - just in case! PS just opened up the back of the switch and no fuse obvious.
Great - simple swap then
