1, the product is not vibration, vibration switch is disconnected state, output, output level green light is not bright;

2, product vibration, the vibration switch conduction, instant output output low level, the green light is on;

3, output can directly to the single chip microcomputer, via single chip microcomputer to detect the high and low level, if there is a vibration environment, at the police
