Introduction to Pressure Switch
A pressure switch is an electro - mechanical device that senses the fluid (liquid or gas) pressure and changes its electrical state when a certain set pressure is reached. It acts as a control element in various systems, providing safety and automation functions. Pressure switches are widely used in industries such as oil and gas, water treatment, HVAC (Heating, Ventilation, and Air Conditioning), and automotive. They can monitor and control pressure levels to ensure the proper operation of equipment, prevent over - pressure or under - pressure situations, and protect the system from damage.
