The "poor man's" accelerometer/motion sensor! 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...

The "poor man's" accelerometer/motion sensor! These spring-vibration switches are medium sensitivity non-directional vibration induced trigger switches. Inside is a medium hardness spring coiled around a long metal pin. When the switch is moved, the spring touches the center pole to make contact.

The "poor man's" accelerometer/motion sensor! These spring-vibration switches are low sensitivity non-directional vibration induced trigger switches. Inside is a stiff 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...

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...
