Description

Features:

  • 1 SW-18010P series are spring type, no directional vibration sensor trigger switch, any angle can trigger
  • 2 Switch is open circuit OFF-state , when it is static, when external force to touch and corresponding vibration, or movement speed achieve adequate (partial) centrifugal force, conductive pick feet will produce instant conductivity is instant ON-state, when external force disappear, switch back to open circuit OFF-state.
  • 3 Switch have the identification P at the bottom, for completely airtight;
  • 4 In the normal, switch life can reach 20,0000 cycles lifespan
  • 5 This series Switches have trigger high sensitivity
  • 6 Apply to security devices toys electronic scales products

Details

Sensor is made up of a small spring mechanism, which makes the contact ON when the applied vibration force is at above a certain threshold. It has two legs coming out of it. Normally the two terminal are insulated by a resistance value more than 10MOhm. When someone applies vibratory force on the switch, spring inside the switch vibrates and makes a momentary short circuit between the two terminals.

Make a simple LED circuit to verify the working of Vibration sensors. Use Vibration Switch as an on-off switch. When vibration of above a threshold is present on the sensor, the LED glows while when there is no applied vibration LED does not glow.

Testing with scope

Testing with oscilloscope is simple. Just give external voltage through vibration sensor. Then the sensor is tapped, it outputs high pules as shown below on actual scope output. There are multiple pulses due to internal spring vibration on tapping.
