Hi All, I'd like to install a smart switch which requires a neutral wire.
The present switch as two live wires and the earth connected to the facing, which i understand is pretty standard. There is also what i think are 4 neutral wires in the housing which are connected to nothing, is it ok just to use one of these for the smart switch? Any ideas why they would be in the housing but not used?
They are probably being used. The "loop in" is at the switch, not at the light. If you use just one of them the other lights will not work. From the picture i see the blacks are terminated in a "choc bloc" connect a wire from this to the neutral of your smart switch.
