Description: Sure, your flashing, chip-tune playing t-shirt is really cool at the party… but at some point you need to turn it off. And yes, you could just pull the battery, or maybe you’ve even sewn a LilyPad slide switch in-line. Wouldn’t it be nice if there was just a switch on the battery? Well look no further.
This LilyPad Coin Cell Battery Holder has a small slide switch installed on the board, in-line with the power so you can shut off your project and save batteries. This slide switch is the same as is found on the LilyPad slide switch board, so it’s not easy to accidentally turn off or on.
Just like the original Coin Cell Battery Holder, this simple board holds a 20mm coin cell battery (such as a CR2032) and gives you 4 connection points (two positive and two negative) for sewing into your project.
Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

This does the job of adding a battery to the project fine. The on off switch is nice. I got two of these this month (march 2015) and one had the battery holder pop off on first use. Had to put on my reflow skillet and add more solder. Holding fine so far.
Way to fix the board! Nice work. So sorry that it popped off in the first place. If you ever have troubles, please feel free to contact our Support staff and we’ll do our best to help resolve the issue. Cheers
I designed a felt wristband with a circuit on it it that lights up if properly sewn. Boys and girls both strongly invest in the project. No kid can tell me they are satisfied with their project if it won’t light so we explore until we find the problem. It is always a short they don’t see. They have to develop some patience to find the problem. Great learning tool!
The solder weld on the tabs is really weak…please fix this problem: when working with teenagers it can be a deal breaker to have their project fail after weeks of sewing.
So sorry to hear about that issue. These are generally pretty solid. If you have ones that fall apart, please contact our Technical Support team. They will be more than happy to help you.
The casing for the battery WILL come off easily. There are many others comments stretching a quite a while back. I had to resort to reattaching it back on my own. Will not be likely to purchase another :(

In my last order there was on battery holder that the solder did not work, but all was fine with this one. Will continue to purchase Lily Pad product!!
Stitched in well, the soldering is solid, and the convenience of a switched battery is great. I did get some weird behavior when I first got it in a circuit where shaking it while in the off position seemed to have some intermittent power to the LEDs. Not sure if the switch was not fully off, or if the switch has some vibrational sensitivity. But all seems fine recently.
This is my first experience with LilyPad. Used to power 2 yellow LED owl eyes for Halloween costume I created. Holder’s small size allowed me to easily hide it under a felt feather in back of hood, which can be lifted to turn on and off. Will definitely be using for future projects.
Such a shame that there aren’t many of these out on the market, this little bugger made my DIY modding project a lot cleaner looking and more compact with me not needing a coin cell battery holder AND a small toggle switch. Great product!
The switch is perfect. The board and solder points are great. The battery holder attachment to the board is a little weak and some of them had to be fiddled with and pressed together to have proper contact.
I was able to sew the holder right into a bracelet using steel thread, as it is lightweight and provides four holes for connecting. The connections worked well. The on/off switch should make it versatile for a number of applications. It fits a CR2025 coin cell battery.
I recently used 2 LilyPad Coin Cell Battery Holders at our school Makerspace and they worked beautifully. It was easy to sew with them using conductive thread and therefore easy to make a complete circuit to light up a sewable LED. There is a small on/off switch so the battery isn’t drained. Great product!
Love that this combines the battery holder and switch together. Works great for small projects where space is at a premium!
Well, I took it out of the package, put the battery in, and one side of the surface mount solder joints popped off immediately. So as of right now it is unusable.
This is just what I ordered for a small 3 volt LED lighting circuit, but it is really on a 30-32mm CB Pad. I’d like to see a double sided LilyPad Button Cell Holder for 2 LR44 batteries (1 each side - 3 volts total) with switch that would fit on your 20mm CB Pad. This smaller size would lend itself to many more uses, including small model lighting. Hope to see this product soon. Good luck.
