A Munters BR01 Pressure Switch responds to pressure changes and switches its contacts to regulate performance within the climate-control assembly.
The pressure switch senses system pressure and opens or closes an electrical circuit when preset pressure conditions are reached, allowing the heating and cooling unit to operate only within its intended range. The Pressure Switch uses a calibrated internal mechanism that matters because accurate, durable response supports safe control, protects connected components and maintains reliable HVAC system performance.
The pressure switch may need to be replaced if the heating and cooling equipment cycles irregularly, fails to start when pressure conditions are correct or shuts down unexpectedly during operation. You might notice physical signs such as cracked housing, worn terminals or corrosion and environmental signs may include moisture exposure, dirt buildup or temperature-related wear that could affect switching accuracy.
