After thinking myself wise, i decided to replace my light switches in the lounge. One operates 3 lights and the other operates 4. I presumed that it would be a simple swap the wires over job and that would be that. However the new 3 light switch has a different layout from the original and has only L1 & L2 ( and the letter 2way) 3 times across the top and three COM1 slots at the bottom. It would also appear that the 3 switch also somehow dictates how the 4 switch operates.
Can someone help please!!
