Wiring question

[dobbollah]

I have just replaced a broken 2 way 2 gang switch and seem to have stumbled across a problem...i'll explain the set up first.

I have 3 lights, 2 x 2 gang s way switches and a 1 gang 2 way swtich.

One of the lights works off one switch. The second light has 2 switches as does the third.

Light 1 - on a 2 gang 2 way switch

light 2 - on 2 x 2 gang 2 way switches

light 3 - on a 2 gang 2 way switch and a 1 gang 2 way switch

I have red, blue, yellow wires and at the mo one switch seems to do more than one thing, and then another switch wont work unless another is on so somethings wrong somewhere..........

Can anyone offer a quick how to to set it all straight I'd be most grateful.

Thanks in advance

Did you note how the old switch was wired ?
Did it work properly before ?

Photo of how you have wired the new switch may help.

At first glance it seems like there is a link in the wrong place......

i took a pic of how the old one was wired yes.....howver thinkng about it im not sure it all worked properly in the first place !

I have the red lead in the common hole (top one right?) in all the switches then yellow/blue in the L1 and L2.

Someyellow/blue are sleeevd some not

Have you altered any of the light fittings or junction boxes? your switching a feed some where. If you have a set of testers switch all off the switches to the off position and test each terminal to see which ones are live and report back.

you'll have to do it by process of elimination, can you see the outer sheath of the cable (grey) usually if so do all of the cores go to the same switch leave your phone number if thats easier i will try talk you through it.

Then you must not do electrical work, end of.

Get an electrician - wiring by random guesswork hoping to hit on the right connections by chance is something only a complete idiot would contemplate.

Sounds as though you've mixed some of the commons up, so that one switch will switch the live on and off to another switch.

Wait, wait....let me get some popcorn.....

In the meantime, if the 1st switch was the one you changed, then the LH common looks like it comes from a different cable to the switchwire.
