Vibration switch

Jaco Pieterse


Good day,


What is the smallest vibration or sound vibration sensor/switch known to activate a pulse or send a signal or close a contact.


I'm currently working on a project to detects vibration to then switch a light on. ( Battery powered 12v ) 


example: Whenever I hit my drums with a drum stick a light must come on. Limited space


Thank you.

Failing the accelerometer - which would be very successful if on a drum - you could connect a microphone to a transistor to switch on the light.

It is a very simple circuit and is reproduced on a number of differing electronics websites. Basically the "switch" would be the microphone. They generally have a resistor in the circuit...if this was a variable resistor, it could be adjustable. daisy chain this to a timer circuit and you're laughing....or drumming!


Good luck!
