A bare spring vibration switch, not a module: a coiled spring inside a sealed metal can that momentarily touches the centre pin when the part is knocked or shaken, from any angle. Closed it is under 5 ohms, open it is over 10 megohms, and it reacts in about 2 ms. It is rated 12V at only 5 mA, so it drives a logic input through a pull-up resistor - never a load. Ideal for tap-to-wake gadgets, tamper alarms and impact detection.
Key features

- About 2 ms response time
- Rated 12V, 5 mA max - logic input only
- Bare 2-pin part, needs a pull-up resistor
- Rated for around 500,000 operations
