Lochinvar & A.O. Smith 100318326 Pressure Switch R-407C As a critical component inThe Lochinvar & A. O. Smith 100318326 Pressure Switch is a critical safety component designed for precise water pressure monitoring in high efficiency Noble Fire Combi Boilers and NKC series units. Engineering to detect low water pressure conditions, this switch acts as a primary fail safe, preventing dry fire scenarios and potential heat exchanger damage by ensuring the burner circuit remains open unless sufficient system pressure is established.
