The Trane SWT1262 is an automatic-reset high limit switch engineered to safeguard furnace and air handler systems from dangerous overheating conditions. When supply-air or heat exchanger temperatures rise to the 250–280°F trip range, the switch opens the control circuit, shutting down the burner or heating element before damage can occur. Once temperatures fall back within the safe operating range, the switch automatically resets — restoring normal operation without requiring a manual reset or service call.
