third light switch

[daveyell]

I\\\'ve added an extension and want to add another switch to the stairs light which is already 2 way on 3 core & earth. How do I join the existing circuit?

Pretty much sums it up.

What do you mean you have added an extension, do you mean you have had one built?

Be sure to turn off the power at the consumer unit before trying anything.
