i have a 3 gang switch.
1st gang is 1 way
2nd gang is 2 way
3rd gang is 1 way
When I opened it up I expected to find
1 of 3 core switch cable and 2 of 2 core switch cable
each gang has 4 terminals two labelled 1 and two labelled 2
However what i found is 1 of 2 core cable and 1 of 3 core cable wired as follows:
N from 2 core going to 1 on 1st gang
L from 2 core going to 1 on 3rd gang
yellow from 3 core going to 1 on 2nd gang
blue from 3 core going to 2 on 2nd gang
L from 3 core going to the other 1 terminal on 1st gang and from this
2 added loops of Live into the free 1 terminals on gangs 2nd and 3rd.
What is this, is it safe/common and more importantly how do I wire on a new replacement 3 gang switch using this method?
