The Low/High Pressure Switch is a vital safety and control component used in HVAC and refrigeration systems to monitor and manage refrigerant pressure levels. It automatically shuts down the compressor or activates alarms when the pressure exceeds safe high or low limits, protecting the system from damage and ensuring efficient operation.
This dual-function switch is commonly installed in air conditioners, chillers, cold storage systems, and industrial refrigeration setups. It is designed to handle fluctuating pressures and provide a reliable response under continuous use.
