DIY CLAP SWITCH

We are now selling fully assembled CLAP SWITCH(shipped from Sydney, Australia). Click here to visit the product page. 

If you have come to this page from a search engine, we recommend you to visit the page about DIY clap switch. In this article, we are going to describe how you can use the “do-it-yourself(DIY) clap switch” to light up 100-240V appliances. When we say 100-240V appliance used with a clap switch, it is usually a bulb/lamp/CFL(Compact Fluorescent Lamp) tube. This article is for absolute beginners, so, we will try to explain all the small details.

The following image shows the basic set up for lighting a bulb.
connecting a wire

As you can see, there are two wires that go inside the bulb holder and to the mains two pin plug.

To operate such a lamp, we simply break one of the wires and connect the broken ends to the relay. One end goes to NC or NO point and the other goes to the common point or pole (P). Check this article to know about connecting an appliance to a relay.

CONNECT LAMP TO CLAP SWITCH

Detail explanation:

Now, let’s see the above illustration in detail. In the last section of this article, I have shown a video where I have controlled a 220V fluorescent tube. The tube is connected to the mains using two wires that have been shown below. I have removed the outer insulation using a wire stripper.

You can also connect the wire ends to NO and P points of screw terminal. You have to do one, not both.

Step 9- Connect a 6V 0r 9V battery to the clap switch and your device is ready. Switch the power supply on using the SPDT switch on the circuit board. Fix it on a wall or inside an enclosure and operate your lamp with your clap.
