In one of my earlier post we learned a simple clap switch circuit which incorporated an IC for implementing the desired flip flop actions. The present design uses a different principle and utilizes only transistors for the above triggering actions.
Looking at the circuit diagram we see that the entire circuit has been configured around ordinary general purpose transistors.
The functioning of the circuit may be understood with the following points:
Transformer X1 along with the D1 and the capacitor C1 forms the basic power supply circuit for providing the required power to the circuit.
The first stage which includes R1, C1, R2, R3, R4 and Q1 form the input sensor circuit.
The next corresponding stages consisting of Q2 and C3 form the flip flop stage and makes sure that the signals from the input sensor stage is appropriately converted into alternate toggling of the output.
The output stage consists of a single transistor Q4. It is basically configured as a relay driver stage for translating the flip flop actions from the previous stage into physical toggling of the connected load across the relay terminals.
