Three Way with Intermediate and Three Wire

[Artur Makars]

Hi, I'm new here, and really hope for advice... Could anyone kindly put me in right direction. How do I go about connecting the second switch on landing, or what have I done wrong so far (attached image)? Whatever is connected now works a treat.

Thanks for your time

Try this. It's all on there
You need a 2way switch at each end and a intermediate switch in between. You can add as many intermediate switches as you like providing you have a 2way switch at each end.

The trouble with this is that my light feed is at intermediate switch... I might be dumb but can’t figure it out

Not a problem, you just connect it to L1 and L2 of the same cable, it makes no difference.
Look at the diagram, follow the wires
And you'll see what I mean.

Thanks, I’ll try that tomorrow

As Mickey said the live and switch wire can be taken to the intermediate switch and put in the terminals there. Just to note the brown is just jointed through the switch.

It is possibly worth pointing out that your original diagram shows each switch to be a double gang two way switch as you have duplication of each of COM L1 and L2.
You would need to have one of your switches as an intermediate switch. Also each switch (if the whole arrangement is only switching the one light) would only need to have a single gang i.e. one switch on each plate.
With the current arrangement you have shown you are lucky if it works correctly as you are splitting the circuit over two different gangs in the same switch plate.
I would start from new for the connections.

Unless its my eyes or I'm missing something, I can't see how the current arrangement works at all other than if its in one certain switch position?

 

[Toneyz]

Yes see what you mean regarding the internals shown for the intermediate switch as long as the O.P. installs an intermediate switch and wire as shown it will work.

As Mickey has posted. I personally use Grey as common and brown as L1 but people do this a little different.

Yup

Correct, I was trying to be diplomatic about my wording!

no no no, do it in order, brown for common/feed , l1 is black, l2 grey and so on.

Mickey has posted a wiring diagramme it is not going to help the O.P. if we confuse him by posting he uses different colours.

I believe in the on site guide it does show the black as common and brown as L1.
I might be wrong, I know I've seen it in one of the regs books.
