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”.
Switch have the identification “P” at the bottom, for completely airtight;
The series of switches, different model has different sensitivity.
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.
