內建開關的密閉式 4AA 電池盒

The switch clicks firmly and the colour-coded leads made wiring my sensor project completely painless. Also love that the lid actually stays put when I snap it closed.

I needed a neat way to power a project without wires everywhere, and this box's detachable lid makes swapping batteries effortless. The switch gives a satisfying click and it's nice to have a clean power control built right in.

The colour-coded leads made wiring this into my project dead simple, and the detachable lid means I can swap out the AAs without wrestling with screws. It's been running my device for a week straight with no loose connections or flickering from the switch.
