Hi all, I was having some work done as I've moved into a new house in Feb. My electrician did all the wiring for a new partition in the front room but has been detained in the EU because of the 2 week isolation period. I've managed to wire up the outlets but have no clue what's going on with this two way switch or how to wire it up - any ideas?

Despite what most folk think, there is no standard colour scheme for wiring lights, and as the cables have no physical description as to what they are connected to, I can only say leave it to your electrician.
