This high-performance High Pressure Switch is a vital safety component designed for HVAC systems, including residential air conditioning units and heat pumps. Engineered to protect your compressor from damage caused by excessive pressure, this switch automatically interrupts the electrical circuit when internal system pressure reaches 650 PSI. Once the pressure safely stabilizes and drops to 450 PSI, the switch closes to resume normal operation. This air-proving pressure sensor ensures long-term reliability and system efficiency by preventing mechanical strain during high-load conditions or refrigerant blockages. Ideal for technicians and DIYers looking to restore proper safety protocols to a cooling or heating system.
