Introduction to Pressure Switch
A pressure switch is an electro - mechanical device that senses the pressure of a fluid, such as air or liquid, and converts it into an electrical signal. It is widely used in various industries, including manufacturing, automotive, aerospace, and HVAC (Heating, Ventilation, and Air Conditioning). The basic principle of a pressure switch involves a pressure - sensitive element, like a diaphragm or a piston, which moves in response to changes in pressure. When the pressure reaches a pre - set level, the switch contacts open or close, triggering an electrical circuit. This simple yet crucial function makes pressure switches essential for controlling systems, ensuring safety, and maintaining the proper operation of equipment.
