What does a limit switch do in a furnace and would it not allow the gas burners to come on?

((what does a limit switch do in a furnace))
It prevents a furnace from overheating and causing a fire.
((and would it not allow the gas burners to come on?))
Yes because allowing the gas valve to come on or stay on will allow the furnace to overheat.
