Lilypad Arduino Coin Cell CR2032 Battery Holders with Switch – Save Batteries, Switch Off LEDs, Pack of 2

I used these to replace the fixed batteries in my daughter's welding helmet. They work perfect and I like that they have a on/off switch.

Love the product. Worked well for my daughter’s simple circuit design.

I got these to put external battery holders on one of my shop tools. They do exactly that. If you need to do that, get these.

So far, I've had 6 out of the 8 solder joints that hold the sheet metal battery holder onto the circuit board break with no more stress than having to hold the battery.For the excessive amount they charged for this item to begin with, the quality is pretty disappointing.

I'm not using this for lilypad, but rather for a laser alignment tool for a milling machine. the mounting holes are just a bit too small for #4 sheet metal screws, but that's the only thing i would ask to change: make those holes 1/8" or 3mm.works well, great value, super quick shipping. Thanks!

Very easy to work with. I used it to power 5 LEDs and they were pretty bright.

Worked great with the LilyPad LEDs. Top notch product.

good
