Shock Sensor 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.
Centrifugal Force Switch Sensor provides ON signals when the device reaches a certain G-value and the inner tiny ball pushes the spring. Applications: TPMS start-up automatically, etc.
