Inside, there's a movable actuator that makes or breaks electrical connections when the unit's energised. An IP40 rating indicates the enclosure is protected against water jets and objects with a diameter of more than 1mm, so it's a sturdy option for industrial use. You'll find this device in applications such as machinery control, safety systems or building automation.
