This high-pressure switch is a critical safety component designed for HVAC systems, including residential and commercial air conditioning units and heat pumps. Functioning as a high-limit cutout, this Single Pole Single Throw (SPST) air pressure switch is engineered to protect the compressor from damage by automatically opening the electrical circuit when internal system pressure reaches 650 PSI. By monitoring refrigerant pressure levels, it prevents equipment failure and ensures the system operates within safe parameters. This durable replacement part is essential for maintaining the longevity and efficiency of your cooling or heating equipment, providing reliable protection against over-pressurization.
