Ok sorry, I read the TWO WAY WIRING.
It said to me "blah blah blah, flibble flibble technomologigal doohicky spangle doobry wotchamacallit boing."
Anyway once agin thank you ALL for your help.
I did however come across an interesting combination before I got your answer in that I could...
Looked at my piece of paper agan, I think I may have transposed two of the terminals.
Anyway I tried the new combination and it all works as it should and I've put the earth wires on.
Thank you all very much.
Housewiring just gives me brain fog. It's one of those things that just doesn't...
I'll try the combo you've suggested.
The downstairs swich is the new one, and I wrote down how the wire went in to all the holes and put them ove one at at a time.
It was the upstairs that I forgot to write down.
Need to sleep now (work nights) will try it this evening.
All the houses...
I messed up. I forgot to write down how the upstairs single switch was wired.
ok downstairs is double switch, operates down lights and upstairs lights.
upstairs is single switch operates only upstairs lights.
double is wired yellow L2 Blue common on one switch
other is deep red L1 black...
