## Description

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. 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!

We also have a version with [a stiffer spring, which is harder to trigger](https://core-electronics.com.au/slow-vibration-sensor-switch-hard-to-trigger.html), and a version with [a very soft spring, which is easier to trigger](https://core-electronics.com.au/fast-vibration-sensor-switch-easy-to-trigger.html)!
