This tiny coin cell battery holder with LED is ideal for small portable or wearable projects. It holds one 20mm coin cell CR2032 (NOT INCLUDED). 20mm are popular coin cells as they are used in keychain lights and remotes and other small toys, so they are easy to get and fairly low cost. 

This battery holder includes three "LED" modes: Quick Flashing, Slower Flickering and Static On. Also includes on/off/mode switch. Press the button to cycle through the modes. (See video)
