What is the purpose of the high-pressure cut-out switch?

The function of the high-pressure cut-out switch is critical for safeguarding the system from potential damage. This switch is designed to monitor the refrigerant pressure within the cooling system. When the pressure exceeds predetermined safe levels, it activates and shuts down the system to prevent various types of damage that could occur from overpressure, such as ruptured hoses or component failure.

By stopping the operation of the system in such circumstances, the high-pressure cut-out switch acts as a protective mechanism, ensuring the longevity and reliability of the equipment. This is an important safety feature in refrigeration and air conditioning systems, as it minimizes the risk of catastrophic failure and maintains the operational integrity of the equipment.
