Do not use this product for projects that are potentially accessible to young children.** 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 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 four connection points (two positive and two negative) for sewing into your project. Additionally, we have strengthened the battery connector on this board in order to ensure that it doesn’t accidentally pop off. Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.
