Evening chaps.
My dining room light is switched from two locations. I have a switch in the dining room (sD) and another in the kitchen (sK)
sK works as it should, that is to say if the light is off, it switches it on, and if the light is on it switches it off.
However. sD only works if sK is in just one of its two positions. In the other sK position, sD does nothing.
Now I do understand how two-way switching works, I used to teach o-level physics, but I don't understand this. Is it wired incorrectly somehow or is it a dodgy switch, and if so, how do I identify which one? sK is a triple-switch plate, two of which are 2-way. The other 2-way circuit works as it should.
BTW, this hasn't suddenly started happening, it's been like it since I moved in, I've just never done anything about it.
All help gratefully received.
