What is the purpose of the single function AC pressure cut-off switch?

The single function AC pressure cut-off switch is designed to protect the air conditioning system from damage caused by abnormal pressure levels. It monitors the refrigerant pressure in the system and automatically shuts off the compressor if the pressure exceeds or falls below a specified threshold. This prevents issues such as compressor failure or inefficient operation, ensuring the system runs safely and effectively. Overall, it enhances the longevity and reliability of the air conditioning unit.
