What is a Pressure Switch?
A Pressure Switch is an automatic control device that monitors the pressure of liquids or gases and activates or deactivates electrical circuits when preset pressure levels are reached. It generally consists of a sensing element (such as diaphragm or piston), a micro switch, and a housing made of cast aluminum or stainless steel. Pressure switches are widely used in hydraulic systems, pneumatic control, water treatment, HVAC, and industrial automation.
