Peter, Do you mean one of these: Unswitched Single Socket http://www.maplin.co.uk/Module.aspx?ModuleNo=220088&C=SO&U=strat15 (of course you can get a switched version). And then fit it into one of these put in the wall: Dry Line Box Single 36mm http://www.maplin.co.uk/Module.aspx?ModuleNo=1294 or have I read your email wrongly? Cheers Chris
