Breadboard-friendly 2.1mm DC Barrel Jack

This power jack is designed to fit 2.1mm power plugs snugly and securely. Perfect for adding a power connector to your project.

We chose the "thin pin" type which snaps into breadboards or perfboards. They also work with "thick pin" types with a bit more solder to fill the larger pads.

• The pin at the end of the jack is the positive pin.
• The pin in the 'middle' of the jack is the negative pin.
• The pin to the 'side' of the jack is switched: when a plug is inserted it floats; when not inserted it is connected to the negative pin.
