York S1-025-22273-003 Limit Switch and 41-409The York S1 025 22273 003 Limit Switch is a critical OEM safety component engineered for precise thermal monitoring in high performance HVAC systems. This SPST automatic reset limit switch is calibrated to open the electrical circuit at 160F, effectively halting operation to prevent heat exchanger damage or unsafe conditions. Once the induction or blower housing temperature stabilizes and drops to the 120F close setpoint, the switch automatically
