SW-18020P Vibration Switch - Shake Switch - Gold Plated Foot 

This is a really simple vibration switch, it use very common in electronics toys, alarm, domestic appliance, electronics devices, smart home system. It is based on Spring System which closes the connection between two terminals when switch vibrates or Shakes.

Tutorial on Testing and Interfacing of SW18020P

Electrical Specs:

• Voltage: less than12V
• Current: <20mA
• Conductive time: about 2ms
• Closed resistance: <10 ohm\
• Open resistance: >10M ohm
• Temperature range: Operating: -40 to 80’C
• Pull force of terminal: 500gf for 1 minute
• Humidity: 95% RH, 40°C for 96 hours
• Operating lifespan: above 200,000 cycles

Application:

• Automotive devices
• Home electrical devices
• automatic power-off function for household appliances
• Air conditon / Air warm blower fall prevention protect switches
• Communication devices
• Toys

Features:

• 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.
