As a sparky, and looking at the state of the job in that photo, I wouldn't take that on for 250 quid. Nothing worse than sorting something where someone's mate 'had a go at it' and ballsed it up

It is not what you think it is. The OP simply took the switches off the wall prior to plastering, bought new switches and is struggling to remember where the wires go on the new switches.

 

As a qualified sparky you would know what to do straight away if a customer asked you to connect 2 switches to existing wiring that worked perfectly with the old switches.  See post No3. Give the OP a break, and a nice price. Blame his wife when you are having a mug of tea & choc digetives afterwards  as she wanted nice new switches after decorating.  😉 🍮

Obelix is right. Flow his instruction.

Here's the diagram

If its a modern installation, it will be wired in flat three core and earth, with a three-plate ceiling rose.

The lights should switch on and off from either switch position. The yellow is live and should be sleeved red.The CPC (earth) should be sleeved yellow and green.

 

It's called " Two-way switching ".

The diagrams that you have given makes it look like an odd arrangement. 

Two-way switching with single way switching available.Single switching of either lamp by the appropriate single pole switch in the two-ganged box. If I'm right it's an odd arrangement-hence all the wires. It's always difficult to disentangle what is being described unless one is actually on the spot.

Modern lighting installation uses the three plate ceiling rose method. Looping in (which provides a live feed for the next ceiling rose) at the ceiling rose.

Ordinarily, one would only need two single ganged-two-way-switches ,for a two-way lighting system.

Tip. Never work on the circuit unless it is properly isolated-eg, dead.

That's always a safe option.

The 18 th Ed of IEE Regs, says any wire that is live at any time must be identified as such .,

Also i want to say guys, i've got new light switches (Schneider Sedna IP20)

Can you also tell me what every hole means so i can fit the properly? Will try to fit them by myself.

Also how can i put two wires into that small holes? Like on a two-way switching for exmple? Is that possible? The holes seems to be just to fit one cable.

You mean the double hole = two wires on each contact ....with the diagram on back of the switch ....

[petemcewan 27]

The switch plate of a two-way switch will have one common terminal and two terminals L1 and L2 usually as a single ganged box. The switching is made from common to L1 or common to L2.

So if you wanted you can have a switch feed (live ) to the common  and a switch wire L1 or L2 to the ceiling rose . It then acts as a single pole switch.

Johnny87,

 

Have you done it yet?
