I recently move into a new house and in each bedroom there is a switch (at the usual socket height just above the skirting) which doesn't appear to do anything. They are not next to any other sockets and are located where I would expect to find a single socket in each room.
I unscrewed the switch to see if it was wired in and there is a single cable (30A I think) connected to it. The cable has red, black and earth without any tape on the black to indicate that it is a switch cable.
As a test, I connected a single socket to it but nothing that I plug into it works. I have checked the other sockets in the room and they are all fine; one in each room has 3 cables instead of the usual 2.
Could anybody suggest a purpose for these switches/sockets or how I could test to what they are?
