Where in the UK do you live and where in the house are the switch and the socket?
What sort of circuit is it?
What cable size is used for it, and what is the rating of the fuse or MCB?
Does it have RCD protection?
What is the socket to be used for?
If it's on the ring you can't just add a switch - what you'd have to do is put a a 13A switched FCU on the ring in place of the socket, and then run the socket off the output of that.
I'm guessing you want the switch somewhere different to where the socket is, so what you could do is put a 13A unswitched FCU in place (could be adjacent to where socket is) on the ring, then run the output of that to a 20A rated switch (NOT a normal lightswitch), which then supplies the socket. Obviously all cabling has to be in safe zones etc...
Not in 1.5mm t+e I hope!Is it permissible to wire one side of the 20amp switch into the ring (ie ring in and out) and run 2.5 mm (or 1.5 mm) cable to the socket from the other side of the switch. Electrically it would seem to be no different from a normal switched socket in the ring (routing of cable excepted)
That seems to be how the under-worktop appliances in my kitchen are arranged (eg washing machine) could the OP do that for his socket?
Torpedo switch on the flex...I am guessing the OP wants to plug his light into a socket that might be awkwardly placed and does not want to have to shift his piano - or whatever - every time he wants to turn it on/off.
