York S1-025-22273-003 SPST A/R Limit Switch 160°F Open 120°F Close

The York S1-025-22273-003 Limit Switch is a temperature control component in HVAC systems that is used to check the internal working conditions. It has been set up as a single-pole, single-throw automatic-reset switch that opens the circuit at 160°F to stop operation when temperatures are too high and closes at 120°F when temperatures are normal. This is used to close the heat exchangers or blower compartments and assists in the protection of the components against overheating, as well as stable and efficient operations.
