These types of switches are sold world wide by the millions for central heating control. Every house in north america with central heating uses a couple and this almost certainly explains the price.[/QUOTE]

That's what mine said as well but when I opened them up the microswitch inside says it's rated to 250V - I did mention this somewhere in this thread.
