General description Pressure switch is mainly used in ventilation and air conditioning systems to control air flow in air ducts, as well as in filters, fins, and fans. It is suitable for air and other non-flammable and non-aggressive gases. This switch can sense pressure changes and is widely used to control the flow of the aerator, monitor fans, and air conditioning systems. Additionally, it is suitable for overheat protection and frost protection in industrial refrigeration systems.
