The 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.

Holds a CR2032 coin cell battery and gives you four connection points (two positive and two negative) for sewing into your project.
Arduino compatible.
Dimensions: 2.9x2.8x0.58mm.
