The mechanical air pressure switch is a purely mechanical deformation that causes the micro switch to act. When the pressure increases, the different sensing pressure components (diaphragms, bellows, pistons) will be deformed, and will move upwards. Through mechanical structures such as railing springs, the uppermost micro-switch will finally be activated to output electrical signals. PW119 series air pressure switch can provide different pressure, differential pressure, vacuum and temperature ranges, and can also provide different connection methods, various materials and pressure sensing element types. It is precisely because of this flexible selection method that PW119 series air pressure switch can be widely used in various places, such as chemical, petrochemical, oil refining, oil field, drilling platform, oil pipeline and pharmaceutical and other industrial processes.
