3 switches for 1 light issue

You could check each WIRE is from each correct CABLE, in case you have mixed some up.

I would be inclined to think you have a faulty switch - you could remove the intermediate switch, and join the two reds in a connector, and the rwo blues in a connector, THEN see if the two 2way switches work correctly.

@ebee I've heard that called the california method and being allowed over in the US at one time, but not anymore (rather like neutral fusing over hear I guess and maybe similar time frames?) I've never seen or heard about it being done over here though and I think we were sensible enough that it was never acceptable (doesn't mean no one ever did it though!)

It gets even more interesting when you realise that the L1 and L2 of the switches could be fed from separate circuits, and even more interesting given its a split phase system, someone moves one onto the other side of the supply

Actually one thing we should all be mindful of is , electrics is fairly simple you just needs to twist wires together.
Doing electrics safely though is a completely different matter!

Thanks everyone, swapped the double for another switch and it works fine. Wish id of tried that sooner!
