Hi
While decorating I am replacing a light and its pull switch above the bed (but not the main wall switch). I was going to do a stright swap but the pull switch has become disconnected so I can't.
The light has the normal black and red in, wired to blue and brown on the light - no problem.
The pull switch (which always opperated OK, but in a slightly odd manner) has three cables, RED, BLUE, ans YELLOW. I've used a 240 AC volt meter and tested which pairs of cables have 240V across them, the results are:
With the main wall switch off there is 240V between Blue and red only,
With the main wall switch on there is 240V between Red and yellow only.
My question is which of the three colours should be wired to which terminals on the new pull switch. (not worried if it opperates as before, or in any other way.)
Many thanks
