Can I fix heat regulator (burner switch) of electric range?
OK, what you're suggesting will probably work. I have similar repairs on "ON &amp; OFF" switches..BUT... The contact at #1 looks like a limiting device to break the circuit in an overheat situation. I wouldn't be messing with that. The problem as I see it is the burners wouldn't turn off. So if your fix doesn't work, the problem will return when you lest expect it..... Is it worth it?  How old it the range?  I'd be, and have done many times, buying a new switch. Many times the internal designs of these switches are improved and you'd never know it by the outside appearance so the existing problem you have might never occur again. My advice is to think twice about messing with range/oven switches. Good luck.
