Need a bit of help please. Wired a 2 way from upstairs to downstairs then customer wanted a 2 way to side of the bed, obviously didn't think it through enough! At the minute i've got mains and switch wire at top of stairs for downlighters and a three core going downstairs and one going to the side of the bed . I want all three switches to work the downlighters. I've never wired an intermediate without mains and switch wire at the first switch and then an inter in the middle before. Is there any way of getting them to work with an intermediate switch at the top of the stairs and the mains and switch wire going into that if you could talk me through it that would be great.
