How to use the clap switch kit (NEW TUTORIAL) 




Description: This FULLY ASSEMBLED sound/clap operated switch can be used for switching your 100-240V AC light bulb. Usually, we use a clap switch to operate a lamp and it can easily do that for you. The kit responses to clap up to distance of 5 meters, but, the further you go, the louder the clap should be. 


  • Operates a 100-220V AC lamp with clap/loud sound.
  • Supply voltage: 5V-9V. Use a AC to DC power supply for better response. 9V battery can also be used, but the kit consumes a lot power while triggering the relay.
  • There are two supply input points: a DC barrel and a 2 pin screw terminal. You can use one of the points to power up the kit.
  • Consists a PTC resettable fuse. Switches the circuit off if there is unexpected flow of current over 500mA.
  • Dimension: 83.82mm x 49.53mm
  • Relay specification: Activation voltage: 5V DC. Controls appliances operating at 10A 250VAC, 10A 125VAC, 10A 30VDC, 10A 28VDC. Suitable for Europe, North America, Australia and New Zealand. 

How did we make it ?

This DIY clap-switch is a combination of two kits: 

a. Low cost clap switch: This clap switch has an LED on it and a loud sound activates the switchCheck out project details.

b. Relay module for the clap switch: The relay module can be connected to the clap-switch operate 100-220V AC lamps. Check out project details.

We simply combined these two kits and made one complete clap-switch kit.

It's a now a fully assembled kit: It comes fully assembled. We test the kit before shipping. We make sure that the relay and all other parts work. We test the kit using a 9V power supply. After everything is confirmed, we ship the kit.

Package contains: 1 x Fully assembled and tested clap switch

  1. Works as described

    Posted by Jessica Piliak on 20th Dec 2016

    It took at least 1 hour for me to build this kit. But it worked at last. Nothing confusing but just several resistors and components to make this simple project. It was fun building this project anyway.

  2. Good kit for beginners

    Perfect kit. I made this project for my school exhibition. Good time with counting people :)
