This 2 x AAA Battery box features a slide and click cover, built in on/off switch the 150mm leads terminate in a JST connector.
The JST connector is that same type of connector found on the micro:bit making it an ideal powering solution for your micro:bit projects.
As the micro:bit has no on/off switch, the battery box's built in switch will allow you to power off your projects without having to disconnect anything. This will also help to extend the working life of the battery box's JST connector.
