Pressure switch or pressure sensor is one of pneumatic equipment, this sensor or switch is electromechanical and operates according to changes in pressure, and it is also designed in such a way that when the pressure around it reaches the set level, the switch is activated. and starts the electrical operation, that is, it can disconnect and connect a current.Pressure switches are divided into two types, mechanical and electronic.
Mechanical pressure switch: Mechanical pressure switch works with physical change caused by pressure. For example, high pressure can cause a diaphragm or piston to move, which ultimately leads to disconnecting or connecting an electrical circuit.
Electronic pressure switch: Electronic pressure switch uses electronic sensors to detect pressure and can have a user interface that allows the user to set the desired pressure to activate the switch. Electronic pressure switch sometimes uses digital communication to read and adjust parameters remotely.
