Hi, I've just come to change our current light switches and this being my first time doing so (I've done plug sockets but not light switches), I've hit a bit of a problem and could do with some help. Taking the panels of the switches I see that each has just two blue wires one going into the com terminal and one into one of the lives. I was under the impression that blue was neutral. Shouldn't one of these be brown (live). The Brown wires and the earth wires seem to be looped through those little plastic boxes behind the switch with only the blue wires actually entering the terminals. Am I OK to just wire the blue wires into identical positions in the new switches. My concern is that I won't know if it is earthed, although I have to assume it is I suppose since it hasn't caused any problems as of yet. Any help or advice would be most welcome. Cheers
