SW-420 for the motorcycle on the vibration sensor
SW-420 is a vibration sensor designed for electric vehicles, vibration sensor alarm on the development of the motorcycle. Because it is simple with the complex structure of a traditional buzzer alarm, magnets and springs, and thus is widely used in recent years in the electric car alarm is the principle of the switch: the switch is turned on at any angle normal state, is subjected to vibration or moving within the switch conduction currents generated by moving or vibrating roller, causing increased current through the resistor is disconnected or the trigger circuit. This feature is usually general switch in the ON state briefly disconnected resistant to vibration, so its high sensitivity, set by the customer according to the requirements of their products sensitivity adjustment.
