York S1-025-31812-000 Rollout Switch With a cut-out temperature ofThe York S1 025 31812 000 Rollout Switch is a critical safety component designed for specific furnace burner assemblies where precise thermal monitoring is non negotiable. This 270 degree furnace switch functions as a NC (normally closed) limit that opens when excessive heat is detected outside the combustion chamber, preventing hazardous conditions resulting from flue gas spillage or heat exchanger breaches. As a manual reset rollout switch, it
