An HP pressure switch is a safety device that opens or closes an electrical circuit based on the system's high-side pressure. In boiler and burner systems, this switch protects components from damage caused by excessive pressure, often shutting down the compressor or burner to prevent failure. It is a common replacement part in maintenance and repair, as switches can wear out over time. A properly functioning HP pressure switch ensures your heating equipment operates safely and efficiently, avoiding costly breakdowns. Whether you are servicing a residential boiler or an industrial burner, this component is essential for reliable operation.
