These brilliant inventions are a blessing for makers designing or using boards with standard 2.1mm DC barrel jacks. We’ve got ‘em with a slide switch and a rocker switch!
Many devices opt against a proper power switch, for size or cost or other design reasons. So, you’re expected to unplug when not in use. But you want something a little fancier! These 2.1mm DC Power Jacks have the same PCB layout as classic non-switched jacks but has a li’l extra on top – a labeled switch!
The switch does exactly what you’d expect: plug in your power supply (up to 16 VDC, 3A) and switch power on and off. On and off! On and off all daayyy-o. You can clicky-clack to your maker heart’s delight! We swear we’re not pulling your lead–I mean, leg, this has a seriously satisfying clack.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
