Add a power switch to any project simply by plugging this between the power supply. This is the most useful thing you never knew you needed! You'll want to pick up a bunch for your electronic projects.

Comes with a 5.5/2.1mm barrel jack on one end an a plug on the other. In between is an in-line switch that is rated for 125V and 2Amps (its normally used for lamps, Adafruit suppose). Since most people will be using it with no more than 12VDC, we think it can probably handle up to 5A at that voltage.

  • Hey guys! First time poster. I've been working on a blaster for my girlfriend's costume, and I thought I would share it with everyone. When triggered, it plays a selected sound effect and flashes the light. Pretty simple :)
  • Coffee Grinder With Arduino
  • Using a few bits and pieces, this ordinary coffee grinder now has two presets to run the motor for a programmable length of time. The idea being that the grinder running for a set amount of time will deliver a certain amount of coffee each button press meaning the beans can be stored unground, keeping them fresher for longer. I completed this project for a friend, Ian, who lives for coffee. Ian wanted the same functionality in h...

    I used to run all my power through a little switch on my breadboard, but I released that the switch was not meant to handle that much load. This switch was the perfect solution.
    Works seamlessly with the "Breadboard-friendly 2.1mm DC barrel jack" to sort out all of your breadboard power needs. (Posted on 6/09/2015)
