York S1-025-32706-000 Limit Switch 150°F Open/120°F Close

The York S1-025-32706-000 limit switch breaks the circuit when the temperature is at 150°F and the circuit is joined when the temperature is below 120°F. This on-off mechanism namely acts to regulate and protect different HVAC parts to stay within the safe threshold. It is used as a measure of temperature in heating, ventilation, and air conditioning systems. It helps avoid overheating of a circuit at high temperatures and resumes operation when the temperature is safe. Heats or burns do not overheat and work efficiently and safely, and cooling systems do not freeze or operate at high or low temperatures.
