Single CR2032 Battery Holder with Three Flashing Modes

This tiny coin cell battery holder is ideal for small portable or wearable projects. It holds one 20mm coin cell (CR2032 is the most popular size) to generate 3V nominal. 20mm coin cells are popular as they are used in keychain lights and remotes and other small topys, so they are easy to get and fairly low cost. And speaking of lights, these battery holder includes three "LED" modes: quick flashing, slower flickering, and static on. Press the button to cycle through the modes. Although designed for LED jewelry, it could be used for other projects that need simple cycling.

The holder is made of plastic and snaps open and closed. You can tape it closed if you need more security. A nice extra includes a squishy on/off/mode switch.

Note: This item does not include any CR2032 coin cells. We do stock those, so why not grab one while you're here.

We also have a battery holder with 2 slots for a nominal 6V and a single-coin holder that is just on/off instead of flashy.
