Description
York S1-025-26392-011 SPST Rollout Limit Switch
The York S1-025-26392-011 is an OEM-grade Single Pole Single Throw (SPST) rollout limit switch engineered to protect furnaces and heating systems from dangerous flame rollout conditions. When burner flames roll out beyond the combustion chamber — due to a blocked heat exchanger, restricted flue, or other fault — this switch detects the abnormal heat and interrupts the circuit to shut down the burner, preventing equipment damage and potential fire hazards.

How It Works
The rollout limit switch is mounted near the burner assembly. Under normal operating conditions, the switch remains closed, allowing the burner circuit to function. If flame rollout occurs and temperatures at the switch location reach 225°F, the switch opens and breaks the circuit, shutting down the burner. The switch resets (closes) once temperatures fall back to 145°F, restoring normal operation.
