2 way lighting

[redface]

how many different ways can you think of for 2 way lighting i thaught nothing could get me but a 2 way system got me today.
they said it worked before i replaced switches i think they talk **** unless there is jb in roof.

i tryed everything and think there are only 3 simple ways but only 3 core going in each switch hoe hard would that be.

The main switch wire could be either, "in the rose" or in a JB under the floor.

Well I take it you have located the live feed to the switches and the switch wire to the light? Should be simple after that.

A pair of strappers, a live feed one end and switch wire the other.

there we we could throw some intermediates in for good luck too

Dont forget the colours are different now black = yellow(L2) ,Red = brown (L1), Gray = blue(L3) Black was neutral and has become Blue so blue is neutral

There are many ways to skin a cat! I have used the junction box method before, if the switch drops are tight conduit and you can only get a single cable down, it's quite useful, if the JB can be located somewhere accessible for inspection, of course. Haven't seen this method in books, probably because best practise is to avoid JBs wherever possible but with a couple of extra connectors I reckon you could even squeeze the whole junction into a ceiling rose.

you coulde also take the live and switchlive to the l1 or l2 terminals in the intermediate. that would confuse anybody working on it.

Sorry it’s wire for wire. I can’t understand how anyone could mess that up!

And how many times do we see the cpc used as a strapper when DIY charlie has had a go!
