Hi all - I have gone to replace the pull switch in the bathroom today and when I have taken the cover off the switch there is some odd wiring that I am unsure what to do with.
Into the com I have a red wire, all good there. However, into L1 is going a black wire and a red wire?
I have no idea if this is safe to replicate as usual as everywhere I can see says to never put these 2 together?
