This keeps the air pressure output by the air compressor within normal use. The pressure setting is adjusted by pre-tightening a spring by an adjusting screw rod in the pressure switch, but the adjusting mode has insufficient precision and causes the stop and start pressure to deviate from a set value due to the deformation of the spring.
The pressure of a conventional air compressor is displayed by a pressure gauge. The pressure gauge has two, and one shows the pressure in the gas holder, and the pressure of gas vent is shown to another one. The traditional pressure gauge is of a needle type, a dial plate is provided with two units of a metric system (bar) and an English system (psi), and although the unit system can be distinguished through the color of scales, the traditional pressure gauge is not intuitive after all.
