The Lennox R102463-01 Pressure Switch is an OEM single-pole, single-throw (SPST) safety control designed to ensure stable furnace and HVAC system performance. This pressure switch actuates at 0.10" WC and resets at 0.25" WC, providing reliable airflow verification during operation. It is used to protect the system from improper draft, blocked vents, and unsafe operating conditions by confirming that the inducer is generating the required pressure levels before ignition occurs. Ideal for Lennox residential and light commercial units, this replacement switch maintains original equipment performance, durability, and operational consistency.
