Battery holder for 2 x AA R6 3V with ON/OFF switch and snap-on cover

R6 battery holder with 3V switch (2 x AA) for Arduino, ESP8266, ESP32

A practical holder with a built-in switch and snap-on cover, designed for two AA batteries connected in series, providing an output voltage of 3V. Thanks to the integrated ON/OFF switch, there is no need for an additional power-disconnect module in your project. The holder is fitted with two leads with factory-stripped ends, which makes mounting and wiring much easier.
