2 x AA Battery Holder with Alligator Clips and Knife Switch - 3V

Double the voltage, double the fun — and this time, with a built-in knife switch! This two-cell AA battery holder delivers a clean 3V DC output through pre-soldered 5 inch (12.7 cm) color-coded leads with alligator clip ends, making it an instant power source for motors, LEDs, buzzers, and all your favorite circuit experiments. But the real star of the show is the integrated knife switch, which lets students physically open and close a circuit with the satisfying snap of a blade contact — a hands-on, visual demonstration of how switches interrupt current flow that no diagram on a whiteboard can match. It's the kind of tactile learning moment that makes electricity click for young scientists.

The sturdy open-frame black plastic housing keeps both AA batteries securely in place with reliable spring contacts, while five mounting holes along the body let you screw the holder directly onto a project board, pegboard, or science fair display for a clean, permanent installation. Pair it with one of our Type 130 or 260 DC motors with alligator clips for an instant, self-contained motor circuit that requires zero soldering and zero frustration. Whether you're introducing Kirchhoff's laws, building a classroom circuit station, or prototyping a simple on/off control system, this battery holder brings together power, switching, and connectivity in one tidy package.
