This device does not respond to sound, it only responds to pysical vibrations.
Vibrations around all axis can be detected.
Vibration sensor makes it possible for vibrations to be detected or measured.
When there is no vibration or tilt, the product is closed-circuit ON/OFF state, in a stable state.
When there is vibration or tilt, the conductive resistance increases or decreases, resulting in a current pulse signal, thus triggering the circuit.
This specific product is suitable for small current circuit tilt and vibration induction triggering.
SW-420 Normally Closed Vibration Sensor Switch.
SW-420 normally closed a highly sensitive axial vibration sensor switch moisture and dustproof housing.
Vibration resistance varies with the intensity of vibrations.
