XDB320 Pressure switch uses a built-in micro switch and sensing hydraulic system pressure and it conveys the electrical signal to electromagnetic directional valve or electric motor to make it change directions or warn and closed circuit so as to achieve the effect of system protection. XDB320 Pressure switch uses liquid pressure to open or close electrical contact hydraulic electrical interface element. When the system pressure achieves the value of the pressure switch setting, it signals and makes electrical components work. It makes the oil pressure release, reverse and execute components realize order action, or closed motor to stop the system from working to provide safety protection.
