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.

  • How many LED’s can you connect to this?

  • Can this power an Adafruit Flora or Gemma?

  • On mine the switch popped right off. Maybe some glue under the two plastic pins that go through the board would help.

  • Hi, I was wondering when this product might be back in stock please?

  • The combination of the battery holder and the switch was so practical, I had to get some right away. However, the solder joints that attach the battery holder were incredibly weak. Installing a battery caused the metal frame to pop off. Both of the boards that I bought had this problem. Re-soldering secures it nicely, but it’s a little awkward soldering on the shirt I had already sewn it into. I suggest reinforcing the solder joints that hold the battery frame before use. Oh, and don’t hold the frame with your finger while you are soldering it. :-)

    • Same thing happened to me. The casing just popped off and the joints don’t take rosen core solder very well, at least when I tried it.
