Description: This is a coin cell holder for the common CR2032 type battery. The holder has a neat pop-in, pop-out feature that makes changing the battery easy. The feet of the holder have a small hole that allow it to be sewn without modification.

One of the first challenges of trying to learn how to integrate electronics with textiles is how to provide power to the electronics system. This little product is inexpensive yet practical for this kind of application, so I plan to include it as a component of instructional kits for “wearable tech” classes in the future.
You probably have no control over the size of those holes I’m guessing! Otherwise this little battery holder is great.
I sponsor a STEM related craft club at my elementary school. Our culminating project was to make a simple LED bracelet with snaps as the on/off switch. These were ¼ the price of the Lilypad coin cell battery holder with the actual switch. They worked just fine. You will need to use a size 7 embroidery needle because the holes on either end of the battery holder used to secure the your fabric are tiny. The end that looks like an “E” is the positive.
