Customer Reviews (4.8 / 5 · 5 reviews)

John E. ★★★★★

The metal ball mechanism is clever and much safer than the old mercury version I was using. Each switch activates reliably at a 30-degree tilt, and the pack of five gives me plenty for my project.

William ★★★★★

I was pleasantly surprised by how responsive these are—just a slight jostle and the circuit closes reliably. Perfect for my simple alarm project.

Avery S. ★★★★★

The metal ball inside rolls smoothly and triggers the switch every time I test it, just like the old mercury ones I used to avoid messing with. Five of them in the pack means I’ve got spares for the next project, and it’s nice knowing they’re ROHS compliant so I don’t have to worry about disposal.
