Description
The York S1-025-26392-001 Limit Switch is a control component used to monitor temperature conditions within heating equipment. It operates as a single-pole single-throw switch that opens at approximately 150F and closes near 110F, regulating safe operating limits in furnaces and air handlers. Installed inside heating assemblies, it interrupts electrical circuits when temperatures exceed set thresholds in HVAC systems. This switch is used in residential and light commercial furnace systems. It is integrated into the safety control circuit to maintain proper airflow and heat exchanger protection during routine heating cycles.
