The clap switch circuits explained here will toggle a connected load ON and OFF in response to alternate clap sounds? Here we discuss 4 unique and simple designs which can be selected as per user preference.
The article talks about what the title suggests – a clap switch. A small electronic circuit when built and integrated to any electrical appliance can be made to switch ON/OFF through mere hand clapping.
The proposed design when integrated to any of your electrical appliance can be used to switch it ON and OFF simply through alternate clapping of your hand. The device becomes more interesting and useful because it does not require any external mechanism or device to carry out the specified operations.
NOTE: An IC 555 circuit can never produce an alternate ON/OFF switching for the load. Instead they will work like monostables and switch ON the load only for sometime and then switch it OFF. So please stay away from cheap misleading circuits online.
Main Application Areas
The main application of the clap switch circuits described below is for controlling home appliances like light bulbs and fans.
Suppose you want to connect a ceiling fan with this circuit so that you can switch it ON or OFF with alternate clap sound, you can easily do it, by wiring the fan 220 V AC input through the relay of the circuit.
Similarly, if you wish to switch a tube light or any 220 V or 120 V AC lamp, just wire it in series with the relay of the clap switch.
The following image shows how to connect fan with the relay
How Sound Vibrations Trigger the Circuit
As you must have noticed the clapping of hands creates a loud sound and is sharp enough to move quite a distance. The generated sound is in fact strong ripples or vibrations created due to the sudden compression of air in between our striking palms.
