Hallsw Power Switch:
Hall Sensors are solid state devices that sense a magnetic field. The Hall Sensor on the Hallsw board provides all the circuitry necessary to provide a switch action. Apply a magnetic field (small magnet) of sufficient strength and the correct orientation and the power FET will switch on, remove the magnetic field and the power FET will switch off.
Note: the Hallsw is NOT waterproof, it needs to be installed in a waterproof housing, potted or coated in a waterproof sealant.
