    Pressure Switch

    Pressure switches have a microswitch inside. They are rated to a specific pressure eg 40 bar. The piston moves out due to the water pressure and in turn, activates the switch. Some are wired in a normally open or closed state. Pressure washers use them to either activate a shutdown timer or used to switch burners on. There are many ways in which they can be used on pressure washers. A common use is on the Karcher cold and hot machines. As soon as the trigger is closed the machine will turn off immediately. This is because the pressure switch shuts the power off to the motor.
