Lochinvar & A.O. Smith 100111317 Pressure Switch 340155-7024 Enhanced Airflow Dynamics: Engineered toThe Lochinvar & A. O. Smith 100111317 Pressure Switch is a critical OEM safety component engineered for precise airflow verification in high efficiency water heaters and boilers. This normally open air pressure switch is calibrated to a fixed set point of 0. 20" WC (Water Column), ensuring the combustion blower is generating sufficient negative pressure before the ignition sequence initiates. As a genuine 100111317 replacement part, it provides the
