Burnham Boiler 80160742 Pressure Switch 0.30" PSI

The Burnham Boiler 80160742 Pressure Switch is a monitoring element used in boiler assemblies to detect specific operating conditions within the system calibrated for a 0.30 PSI setting, it reacts to pressure changes and initiates an electrical response when the designated level is reached. The switch is typically connected to control circuits that rely on pressure confirmation during equipment operation. Found in boiler-based HVAC systems, it assists with transmitting pressure-related signals between sensing and control sections, allowing operational sequences to proceed according to established pressure requirements.
