Description
LilyPad Coin Cell Battery Holder 20mm
Features a small slide switch
Lets you shut off your project and save batteries
Provides 4 connection points (two positives and two negatives)
Can hold a 20mm coin cell battery (CR2032)
The LilyPad Coin Cell Battery Holder 20mm 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 positives and two negatives) for sewing into your project.
I really just want a through-hole 2032/2025 clip to solder onto PCBs. These never really fit that well into my projects but having the switch included makes them too convenient to stop. It also seems that LilyPad makes these "wearable" items quite robust.

Which 20mm battery?
Somewhat ridiculously, the description here only says 20mm (diameter) battery, but not the specific model (ie: thickness). According to Sparkfun's site, this takes a CR2032.
