Description
The NTI Boiler 65118663 Low Pressure Switch is a sensing switch that monitors water or system pressure levels within boiler operation circuits. It operates using an internal diaphragm that reacts to pressure changes, opening or closing an electrical circuit when pressure drops below or rises above the set threshold. Across HVAC equipment, it is commonly integrated in boiler systems to detect low-pressure conditions and signal control logic for corrective action. Mounted on the pressure line or system manifold, it connects directly into the control wiring, enabling continuous pressure supervision and coordinated system response during heating operation.
