Make a Tiny 9V Battery Power Switch From Parts of an Old 9V Battery
When you’re creating your own electronics projects, it’s not always easy to find a simple power switch. If you have projects that use 9V batteries , this ultra small power switch is fairly easy to assemble and is mostly made from an old 9V battery.
Sean Michael Ragan of Make wanted to find an easy way to shut down your own projects without shutting down the entire battery. He couldn’t find a 9V power switch to buy, so he made one himself. To make your own, you’ll need wires, a small slide switch, and some soldering skills. In addition, the rest of the assembly is made up of parts from an old 9-volt battery. After you put everything together and test everything, you can clip the 9V battery and easily turn it on and off. For full instructions follow the link below.
