I've just replaced a 1 gang socket in my living room with a Volex 1 gang to 2 gang socket converter. I plugged an iron in to test both the sockets, both worked sockets but I noticed when I turned off one of them that there was a blue flash when I flicked the switch off.
This doesn't seem normal to me, so what could the problem be?
