This LilyPad Coin Cell Battery Holder has a small slide switch installed on it, in line with the power, so you can shut off your project and save batteries. The slide switch has a fairly low profile, so it's not easy to turn off or on accidentally.
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.
LilyPad is a wearable e-textile technology developed by Leah Buechley. Each LilyPad is designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. Most are even washable — just remove the battery first!
See our LilyPad category to find more LilyPad components and conductive thread you can use to sew a circuit into clothing.
Note: The battery frame is mounted on the board — not through it, so take care not to apply too much force when installing or removing a battery or you could snap it off its solder joints.
