When S is connected, square wave oscillator will begin to work, and IC's pin 3 will output square wave pulse signals. When IC's pin 3 outputs high level, V is connected and T's W1 will have current. When IC's pin 3 outputs low level, V is disconnected and W1's current is cut off, W2 will generate high voltage. EL will be illuminated by the high voltage.
