AA Battery Holder 3 Cell + On/Off Switch
The AA Battery Holder (3-Cell + On/Off Switch) is designed to hold three AA batteries in series. With alkaline batteries, it delivers 4.5V, and with rechargeable NiMH batteries, it outputs around 3.6V. This makes it ideal for projects that require a reliable and slightly higher voltage source compared to 2-cell holders.
The case is made of durable ABS plastic, offering strength and long-lasting performance. Inside, nickel-plated contacts and springs provide stable conductivity and secure battery positioning. Its durable ABS body, and wire leads—ideal for Arduino, LEDs, and DIY projects. An integrated On/Off switch gives you direct power control without unplugging the wires. This makes it convenient for circuits that need frequent power switching during testing or daily use.
Its compact design, strong build, and convenient switch make it an excellent choice for hobbyists, students, and professionals who need a safe, reliable battery power supply. The holder also includes pre-soldered wire leads (red for positive, black for negative). These wires allow easy integration into breadboards, Arduino projects, toys, LED circuits, and custom enclosures.
