Please help.
I've got a two way switch downstairs which operates the hall light (1 pendant) and the other switch operates the upstairs landing lights (3 separate pendants). There is then a 2 way switch (I think see later) upstairs which also operates the same lights. Then there is a switch at the bottom of the landing which operates only the landing lights.
The problem is with the second switch as are is 4 lots of power cabling coming into the wall mounting box each with their own 3 / 4 cables. The original switch itself has 4 L1's and 4 L2's in all (2 lots on each side) with NO com option. The new switch has a COM, L1 and L2 on each of the 2 switches. How do I wire this all up as it all sounds like a right mess.
