Mains remote controls
I'd be grateful if anyone can PM me with details of ANY (UK) mains remote switching that operates along mains wiring (not wireless). I bought a 'wireless' set from Maplins which claimed 'up to 25 metres in open air' and it tops out at around 12 in open air(!) so it is no good for the purpose and I am trying to get my money back - they say "it only says 'up to 25m' " so BEWARE!
I've googled till I drop and cannot find a 'wired' system.
