## Description

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](https://core-electronics.com.au/search/?q=vibration), this one is flat, and will solder nicely into a PCB without sticking up, and is also breadboard friendly.
