The Crash sensor (Right) is a miniature snap-action switch, also trademarked and frequently known as a micro switch. It is an electric switch that is actuated by very little physical force. Micro switches are very widely used; among their applications are appliances, machinery, industrial controls, vehicles, and many other places for control of electrical circuits. They are usually rated to carry current in control circuits only, although some switches can be directly used to control small motors, solenoids, lamps, or other devices.
This is a small micro switch sensor designed for the Arduino. It integrates a pull-up resistor and a status indicator LED on board. That makes it easier for testing! The miniature snap-action micro switch with roller lever make it suitable for many environment detection applications.
