• Barrel Jack Power Adapter Female

This is the standard DC power adapter with 2.1 mm center hole. This jack is compatible with many wall wart power supplies. The power adapter has three pins: pin 1 is connected to the center pole and comes out of the back of the adapter, pin 2 comes out of the bottom of the jack and is connected to the side wall, and pin 3 comes out the side of the jack and is automatically switched based on whether there is anything plugged into the jack. When the jack is not plugged, pins 2 and 3 are shorted together; with an adapter plugged, pin 3 is disconnected. This feature makes it easy to create a system that is powered by a wall adapter when one is plugged into the jack and by a battery the remainder of the time.
