I have a forced air Coleman electric furnace 3nelement, 2 of the micro switches are burned out I cannot buy new ones are there jobber switch that I can use

There are literally hundreds of styles of micro-switches available. If you were to look thru: https://www.mouser.com/Electromechanical/Switches/Basic-Snap-Action-Switches/_/N-5g2v?Keyword=microswitch&No=25&FS=True

Or do a search for micro-switches, I am sure you will find the exact replacement for yours.

What exactly are the micro switches for? Most I have seen are for the air handler door, or the pan. They are both NO (Normally Open) switches.
