Up until now i have had a single bathroom switch (outside bathroom!) that powers the lights and the fan/light all together. However wanted to split the fan off and have a double switch , 1 switch for lights and one switch for fan/light. Therefore have introduced a 3 core and earth and double switch and now have the following: Switch one ; controls all lights (inc light in fan) Switch two; controls fan So far as i can see the fan has both perm live and switch live in it .... however Switch one: turns lights on all fine switch 2 (fan): only works if the light (switch one) is in the on position Then the overrun timer works. If you have both switches in the off position and try just turning the fan on it doesn't work at all so for example if you wanted to just have the fan on in daylight hours whilst showering , you cant! any advice ...have tried swapping everything around and about to go crazy!!!!
Tricky ain't it?! Just having a think about this...it can be done, although it's not perfect. You'll need a double light switch, but each switch must be a 2 way. This is how it works. Sw1(lights/fan) Sw2 (fan only) The only problem is, if sw2 is left in 'on' position, when you flick sw1 'on', the fan won't come on till you flick sw2 'off'. This could be useful though as it means you can have the following. Lights/fan on together Fan on Lights on A 2way switch has a common and 2 outputs. The common will be connected to one output with the switch in one position and then connects the common to the other output when you flick the switch. I'll put a diagram below
Btw, you should have a 3 pole isolator between fan feed and fan In diagram sw1 is shown in 'on' position. Sw2 is shown in 'off' position
Double pole switch for lights and fan and 1way switch for just fan. One pole on double pole switch switches fan and the other pole switches lights....this way when you just operate the fan switch it doesn't bring the lights on. Use click mini grid and it'll look like a normal switch rather than a grid switch.
Thanks for the reply so does that mean by doing this you will still get the run in timer working when you are only using the fan and you turn it off after use ?
