Lochinvar & A.O. Smith 100166156 Pressure Switch Els PW 17895 the internal slide may beThe Lochinvar and A. O. Smith 100166156 Air Pressure Switch is a critical safety component designed for precise differential pressure sensing in high efficiency water heaters and boilers. This switch, which is identical to PRS2405, monitors the venting system to ensure the combustion blower is moving sufficient air for safe operation before the ignition sequence begins. Built to handle low positive or negative pressure fluctuations, it prevents short
