When the temperature reaches the \u003cstrong\u003eopening threshold of 140°F\u003c\/strong\u003e, the switch opens to interrupt the circuit and prevent overheating. Once temperatures drop back down to \u003cstrong\u003e120°F\u003c\/strong\u003e, the switch automatically resets and closes the circuit — no manual intervention required.\u003c\/p\u003e\n\n\u003ch3\u003eAuto Reset Convenience\u003c\/h3\u003e\n\u003cp\u003eFeaturing an \u003cstrong\u003eautomatic reset function\u003c\/strong\u003e, this limit switch eliminates the need for manual resets after a temperature trip event.
