SW-420 for the vibration sensors on the motorcycle

SW-420 vibration sensor is designed for electric vehicles, vibration sensor alarm on the development of the motorcycle. Because it briefly the buzzer with the complex structure on a conventional alarm, magnets plus spring, so widely used in recent years in the electric car alarm principles of this switch is: any angle switches are usually the ON state, is subjected to vibration or movement of the switching conduction currents will produce movement or vibration of the roller, resulting in increased current through the resistor, or disconnection of the trigger circuit. This feature is usually the general switch in the ON state briefly disconnected resistant to vibration, so its high sensitivity, set by the customer sensitivity requirements of their products may be adjusted.
