2-way light switch wiring

Unusual to have to replace a switch on such a new installation?

However, what you appear to have is a Triple & Earth between the two switches and a TW&E switch drop - correctly sleeved. You should be able to see which groups of wires come from which cable - the TW&E will be brown and blue sleeved brown, the triple brown grey and black. That the browns are a different shade is a red herring...

Below is the wiring diagram for a two way switch - ignore the centre intermediate.

L1 L1 0===========0 0===========0============= Line | \ / | C 0================================O C \ / \ / 0===========0 0===========0============= Switch return L2 Optional L2 Intermediate You really need to check the switch at the other end of the two-way circuit as there isn't a standard set in blood for which colour goes to which terminal as regards the triple cable. However, if you can't just experiment until it works - you won't blow a fuse or whatever. Just keep the switch pair wired to L1&2 - that doesn't vary.

OK, so you have new harmonised colours

That depends, where did they each previously go on the switch you have removed?

That ascii might be confusing to the OP as he is reading this via Google Groups. Even I am not sure how IE can display a fixed font.

Maybe this link will help.

Good. Another reason to get a proper newsgroup feed. As if one was needed.

Another reason then to get a decent newsreader. There are good free ones out there.

Amen

IE _can_ display fixed fonts - TOOLS-OPTIONS-READ-FONTS .... pick a font..

It makes sense when composing a post to a newsgroup to use a fixed size font anyway.

Thanks for all the help so far. I still can't work it out - let me rephrase as follows.

There are 2 groups of wires coming out of the wall.

Grey - Common Brown - L1 Black - L2

The other group has 2 wires, blue (with brown sleeve) and brown. Where do these go?

(I'm not counting the earth wires which are connected to the box).

Thanks.

I don't know

I don't know

I'd suggest you look again at the diagram I posted. If you can't follow a simple one like that, I'd get an electrician in.

L1 and L2 along with the brown and black wires...

Just to add, check the other switch and make sure the Grey, brown and black wires are wired to the same terminals.

I covered all that in my first post. And it's a worry that people seem incapable of reading the most simple of wiring diagrams.

Not necessary - simply click 'Show Options' and then 'Show Original'.

There are many reasons why the OP might need to use web-based newsgroup access .

Then they must accept the restrictions of doing so.

In this case there aren't any restrictions - I already explained how they could easily view the wiring post in a fixed-width font.

But please, let's not start another 'Google Groups - for against' thread... :-)

But I didn't start it. Nor did the OP complain about the ASCII 'art' not rendering, so go and moan to someone else. ;-)
