Light switch wiring

[Alexis2782]

Just changing the light switches around my flat and am having trouble with the last three - a three way switch and two singles.

My current switch wiring is on the left - the new ones are on the right. Can anyone help? It doesn't help that every single wire is brown and just mirroring the wiring doesn't work.

old to new
L1=L
L2=L1
L3=L2

The other two switches are intermediate switches where the original are two way.
Makes and models of intermediate switches are varied and so are the terminals in relationship to the way they will work.
But I would go
old-new
L1=L1
L2=L3

But a couple of minutes with a multimeter will sort out how any particular one works.
