PRESSURE SWITCHES
A pressure switch is simply a device that reacts to the changing pressure in a system.
 As it reacts to the pressure change in a compressed air system, the pressure switch either allows or drops an outgoing signal that is used to initiate an action.
for air compressor applications, the action is to turn on or turn off the electric motor or magnetic starter of the air compressor.
