3 way lighting wiring

I am trying to wire the hall lights so that they can be turned on/off at top, middle floor and bottom. In the UK 2 way switches have the correct connections by running 3 core plus earth between them. I’ve got no problem with the cable circuits, it’s just that I cant find suitable switches in any brico stores. They only have 3 terminals on the back.
Anybody got ideas – at worst I’ll have to bring UK ones out but then risk not getting them certified [it’s a new installation].

in France you don’t find the UK type of switches since they use télérupteurs, touchbutton-operated relays (not sure whether touchbutton is the proper UK equivalent for bouton pressoir).
Wiring is simple, see this scheme.
I would prefer the 4-wire solution. I do hope that this scheme speaks for itself, and you can easily see that you can add as many touchbuttons as you like.
The components are called:
You’ll find them in any brico shed.

If you do go the telerupeurs, get the silent electronic type, I find the noise the mechanical relay makes very intrusive when you switch the lights on and off, however you can go the three wire route you are used to with a Va-et-vent at either end of the circuit and a Permutateur (intermediate) between, all shown on page 370 of Thierry Gallauziaux and David Fedullo’s book L’installation electrique, in French I’m afraid, but the pics are self explanatory, thanks due to Robert Arthur for recommending this to us all.
In the illustrations they show how to use a double switch as an intermediate I will try to scan this in and post here, but I am just on my way out fishing for the day and will not be back till late, so it may be tomorrow before I can post it.

Chris, language and naming conventions. Not to explain it to you, but to those less familiar with French electrics. The French will probably be more familiar with the name: bouton poussoir as you already mentioned, not bouton pressoir. It is a touch button, but not a “maintained button”, toggle or on/off. It is only a momentary action for this push down switch, generating a short pulse to get the bistable relay inside your télérupteur moving from one position to the other. On/off from a distance. These relays can be inside your consumer unit, or somewhere in a back box, block type.

He wasnt sure of the English term, I use “momentary pushbutton” which is a rather more technically correct term, many others just use pushbutton.
A pushsbotton could be a push on, push off action (latching) so I prefer to be correct and say “momentary pushbutton” and to be absolutely correct one should say “momentary pushbutton switch” and if you are a military person then “momentary pushbutton switch, lighting for the use of”25th February 2015 at 10:48 #159975725th February 2015 at 11:43 #1599771

If the OP intends to use a permutateur, consider that they will usually require a deeper back box for ease of wiring, because the permutateur is a much bigger animal than a normal switch. 50mm as opposed to the normal 40mm that is more standard for light switches.

I found the pieces made by Legrand in Leroy Merlin but Spain a few years back no chance in France25th February 2015 at 22:24 #1599962
I bought two permutateur’s in Leroy Merlin in PERIGUEUX (Chancelade) three months ago, once I knew what to ask for it was easy.

Much the same as it is unlikely to find intermediate switches in a UK DIY place, the same is true here. You will though find them in any electrical wholesaler in your nearest ZI such as Rexel. As already said, ask for permatateur, but I know two places near me where they recognise them as intermediates as well.
Leboncoin generally has quite a few also. Cheaper.

Maybe I’m being thick here, but I don’t get the OP’s problem. The ‘Va et vient’ switches have threee terminals as shown in Mike’s picture on the left, so what’s the difficulty. Why the need for unnecessary complications. I’ve never had any difficulty finding ‘va et vient’ switches in any of the brico’s. In what way do they differ from the connections on UK switches ?
Apologies if I’m missing something. Perhaps I’ve been doing things wrong.

Zombywoof, the OP wants 3 switches and doesn’t want to complicate things even further demanding 5 switches. That’s where the French télérupteur would be much easier. Rephrasing: where to find an intermediate switch (permutateur) if allowed in France.

You cannot create three way switching with three two way switches. Hence the need for an intermediate switch or the suggested other solution using a relay.
