Can anyone help?
I am moving a light switch (as a result of changing the hanging of a door to open to the right) and have noticed that all the loop wiring is through the switch rather than the ceiling rose. Is this normal?
The switch I am moving is on the opposite side of the wall to another switch and the two switches are looped together. My question however is that the switch on the other side of the wall (which I am not moving) has 4 cables? I can understand why there would be three (2 circuit and 1 switch) but why 4?
An explanation from an expert would be greatly appreciated!
