Flat Vibration Switch - Breadboard friendly

This is a low sensitivity , directional vibration-induced trigger switch. Inside is a very soft spring coiled around a long metal pin. When the switch is bumped from the side only , the spring attached to the first pin touches the center pole to make contact with the second pin. So when there's a bump, the two pins will act like a closed switch. When everything is still, the switch is open. Great for educational projects and wearables!

Compared to most vibration switches , this one is flat, and will solder nicely into a PCB without sticking up, and is also breadboard friendly.
