## Description

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

They also have [a version with a slightly stiffer spring which makes it harder to trigger](https://core-electronics.com.au/medium-vibration-sensor-switch.html), and [a version with a much more stiff spring which is even harder to trigger](https://core-electronics.com.au/slow-vibration-sensor-switch-hard-to-trigger.html)!
