I had a "red key" cut out fail and it caused a little head scratching since the switch still showed electrical continuity when closed and none when open, so appeared to be working, but it had deterorated so that it couldn't handle the high current for the starter. To be fair, it was about fifteen years old.

As with Colin's experience, I have recently had a "red key" switch fail on starter demand after about 20 years service; I found how to get a good quantity of Servisol switch cleaner into the little devil and, after about 20 "no-current" operations, the approx. 1Ω contact resistance, that was the problem, dropped to a few milli ohms. Problem solved for the time being but, replacement switch on the shelf!!
