This brilliant invention is a blessing for makers designing or using boards with standard 2.1mm DC barrel jacks. 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!This 2.1mm DC Power Jack with Slide Switch has the same PCB layout as classic non-switched jacks but has a li'l extra on top - a labeled slide switch! The slide 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 day. 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. https://elecena.pl/product/29478276/adafruit-2-1mm-dc-power-jack-with-slide-switch 2025-11-03 https://elecena.pl/product/29478276/adafruit-2-1mm-dc-power-jack-with-slide-switch 2025-12-03 https://elecena.pl/product/29478276/adafruit-2-1mm-dc-power-jack-with-slide-switch 2025-12-14 https://elecena.pl/product/29478276/adafruit-2-1mm-dc-power-jack-with-slide-switch 2025-12-20 https://elecena.pl/product/29478276/adafruit-2-1mm-dc-power-jack-with-slide-switch 2026-01-24 https://elecena.pl/product/29478276/adafruit-2-1mm-dc-power-jack-with-slide-switch 2026-01-29 https://elecena.pl/product/29478276/adafruit-2-1mm-dc-power-jack-with-slide-switch 2026-04-08 https://elecena.pl/product/29478276/adafruit-2-1mm-dc-power-jack-with-slide-switch 2026-04-20
