Fair enough - but, if it were me, I think I might decide that (even at the eBay price) that was an awful lot of money to spend so that I didn't hear the occasional click of a light switchI will go for a RetroTouch switch www.retrotouch.co.uk edit: wait. No I won't. They are £33 each on ebay. And I have 6 switches in my flat.
Kind Regards, John
