Tilt Switch is also known as Angle Sensor, Angle Switch, Tilt Sensor, Tip-Over Switch or Anti-Dumping Switch.Angle options of Tilt Switch: 15°, 20°, 30°, 45°, 65°
Tilt Switch provides a simple ON/OFF signal when the application tilts to a certain angle according to each tilt switch. Once the signal changed, the trigger function of your design will be executed automatically.
There are a variety of applications for Tilt Switch, e.g. Automatic power-off for smart home appliances like heaters or irons, screen rotation for monitors, anti-theft system, auto-awake system for power-saving, etc. Any kind of application which needs tilt detection is suitable.

Vibration Sensor also called Vibration Switch.Vibration Sensor provides signals when the device shakes or being destroyed. Thus, vibration sensors could be applied for anti-theft system, auto-awake function, etc. Trigger function depends on your own design.

Rotation Sensor is used to detect 4 different directions in vertical position. It could be applied to screen rotation functions for monitors. Or any devices which need left/right towards 45 degrees detection, e.g. smart lock.

Shock Sensor Switch is similar to Vibration Sensor Switch. When the device is shaking or being shocked, the shock sensor provides signals to trigger the function, e.g. alarm sound or sending a warning notice to the server. It could be used to turn on/off devices as an auto-awake function as well.
