When there is 220V voltage, T's secondary winding W2 will generate hundreds of induced voltage. The voltage will be sent to VT's positive pole. T1's W3 will generate 6V alternating voltage, which will be sent to V1's emitting pole and K's magnetic coil. When mouse comes to eat the food hung on the pole, V1 will be connected and output high level, which will be sent to VT, making VT connected. The pulse high voltage will kill the mouse. At the same time, V1's high level will be sent to V2's base through VD6 and R3, making V2 and K connected. So the normally open contactor will be connected,and force HAtomake a warning sound.
