The York S1-025-26392-005 SPST Auto Reset Rollout Switch 225F Open 145F Close monitors heat conditions near the burner area and interrupts the electrical circuit when abnormal temperatures are detected. The sensing mechanism responds to excessive heat by stopping operation before high temperatures affect surrounding sections. In HVAC systems, it works as a safety control around combustion areas where temperature protection is required. After conditions return to the normal range, the switch resets automatically, allowing the equipment sequence to continue while maintaining controlled heating operation and protecting connected internal sections.
