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 Rocker 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 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. We also have a version with a slide switch here Specifications * Electrical Rating: 15VDC 2.5A * Contact Resistance: < 20 mΩ (initial) * Insulation Resistance: > 1000 MΩ @ 500VDC * Dielectric Strength: > 1500V @ 1 min. * Life: 6,000 cycles * Contact material: Copper alloy with silver plating * Switch Circuit: SPDT * RoHS compliant: Yes * Product Dimensions: 28.0mm x 16.8mm x 8.9mm * Product Weight: 3.0g Resources * Diagram https://elecena.pl/product/24023378/2-1mm-dc-power-jack-with-rocker-switch 2023-08-10 https://elecena.pl/product/24023378/2-1mm-dc-power-jack-with-rocker-switch 2023-12-27 https://elecena.pl/product/24023378/2-1mm-dc-power-jack-with-rocker-switch 2024-09-19 https://elecena.pl/product/24023378/2-1mm-dc-power-jack-with-rocker-switch 2024-11-29 https://elecena.pl/product/24023378/2-1mm-dc-power-jack-with-rocker-switch 2024-11-30 https://elecena.pl/product/24023378/2-1mm-dc-power-jack-with-rocker-switch 2025-11-28 https://elecena.pl/product/24023378/2-1mm-dc-power-jack-with-rocker-switch 2025-11-29
