Turn it on? Find the power cable end, and plug it in.

Turn it off? Unplug it, drop cable, and immediately lose the end.

Oy. If you have a project that you need to cycle power to often, you’ll wonder why the project just doesn’t have a power switch of its own (we’re looking at you, Arduino!). Although you can manually yank the power out of the socket, it’s often inconvenient or impossible due to mounting concerns. This little power switch solves this problem by adding a nice little toggle switch in between your power supply and the board.
