Inspired by a recent topic on Wylex main switches, I thought we could discuss 40-50 amp dp pull cord switches, typically for showers.
One question has to be - Do they burn out solely because the terminals aren't tightened/copper wire isn't clean and shiny?
Or are they badly made inside?
I remember fitting a cheap one once and I KNOW I tightened everything up as I was checking all the time I was offering the faceplate to the back box. It burnt out three years later. The MK replacement has lasted 7 years so far to my knowledge.
Another question is WHY are these things so bad? WHY hasn't anyone done anything to improve these?
Another problem with these things is the pull cord can jamn up, or the cord has to be pulled several times before they function.
As you all probably know, only the round Crabtree ones seem to be any good.
