These spring-vibration switches are high sensitivity non-directional vibration induced trigger switches.

Inside is a very soft spring coiled around a long metal pin. When the switch is moved, the spring touches the center pole to make contact. So, when there's motion, the two pins will act like a closed switch.

When everything is still, the switch is open. Great for basic projects and wearables!
