AA Battery Holder 2 Cell + On/Off Switch

AA Battery Holder 2 Cell + On/Off Switch

The AA Battery Holder (2-Cell with On/Off Switch) is a compact and reliable way to power electronic circuits and small devices. It holds two standard AA batteries in series. This provides a combined output of 3V when using 1.5V alkaline cells, or 2.4V when using rechargeable NiMH cells.

The body is made of durable ABS plastic that protects the batteries and ensures a long service life. Inside, nickel-plated steel springs and contacts provide a secure grip and stable conductivity. The holder also includes pre-soldered leads (red = positive, black = negative) for easy connection.

A built-in On/Off toggle switch makes this holder ideal for projects where you need direct power control without adding extra components. You can quickly turn your circuit on or off without disconnecting wires. This is useful for prototypes, school projects, and portable electronics.

Thanks to its compact size, the holder fits easily inside enclosures and DIY builds. It works well with Arduino, ESP32, Raspberry Pi, and other microcontrollers. It’s also popular in toys, LED circuits, science kits, and low-power DIY gadgets.

By using rechargeable AA cells, you save money and reduce environmental waste. The holder ensures flexibility, safety, and ease of use for makers, students, and professionals alike.
