Electrical – How to install this double switch

electricalswitch

After totally re-shape my stairwell i got some issue to re-cable my double switch.

I tried a lot of combinaisons, read some docs but nothing works…

Here is the settings:

That switch is a double one, it's located on the first floor landing.

The first switch command a lamp located between the ground floor and the first floor. Only 2 switch can light the lamp up, this switch and one located in the dinning room.

The second part of the switch command a lamp located btw the 1st and the 2nd floor, this lamp can be light up with 3 switch, the one i can't setup and two others on the 2nd floor.

Where i want to setup the switch

i got 2 wire which comes from the downstairs: one brown and one
orange.

I got 3 wire come from upstairs: one red and 2 orange

I also got a brown wire which wich come throught the wall, from a lamp
in the bedroom

.

Do you have any tips to make it works ?
It used to works properly but i can't figure out what was the correct setup

J'ai deux fils qui viennent du bas : un orange et un marron
J'ai trois fils qui viennent du haut: un rouge, deux oranges
et bizarrement, j'ai un fil marron qui fait juste la jointure entre cet int̩rrupteur et celui de la chambre Рinterrupteur simple juste de l'autre cot̩ du mur.

Sorry about using this as an extension of the comment, there is no place in the comments for sketches to depict what is needed.

This is an illustration to add to the comment I made about a wiring diagram, to help show my referral to a small sketch. It can be a simple line drawing. scanned and posted or drawn with a program on your computer, like Paint for Windows or a Mac equivalent.

It would need to be made a little more extensive to cover all floors.

It really should take an electrician with a tone box to diagnose where the wires go to and from.... But there is hope as long as the conditions are described accurately
