SW-18020P - Sealed Vibration Switch, Shaking Vibration Sensor Switch

Vibration sensor SW-18020 is a piezoelectric accelerometer that senses vibration. It is a switch that reacts (connects) to vibration, ie. moves. When a force acts on the sensor, it is connected, and when the force does not work, it is not connected.

• SW-18020 series is spring type, Non-direction vibration induced trigger switches, any angle can be trigger.
• The series of switches, at the rest is open circuit “OFF-state”, When the external force to touch and reach the corresponding vibration, Or move in speed to reach the adequate centrifugal force. The conductive feet will be conduct instantaneously “ON-State”. When the external force disappear, the switches will be revert the “OFF-State”.
• In the normal, the switches lifespan can be reached 200,000 cycles.
• Suitable for the toys, anti-theft alarm system, electronics scales etc electronic product.
• It doesn’t have a direction, normally it’s open circuit inside, and it turns to close when it is shaked  instantly, and then turn to open again when motion is gone.
