A mosquito fly swatter with a printed circuit board (PCB) typically refers to an electric bug zapper that uses electricity to kill insects upon contact. The PCB serves as the heart of the device, housing the necessary electronic components such as a transformer, oscillator, and grid electrodes. When an insect comes into contact with the electrified grid, it completes an electrical circuit, resulting in a lethal shock that kills the insect instantly. The PCB in a mosquito fly swatter is designed to be compact and efficient, providing the necessary power and control to operate the device safely and effectively. It often includes features like a UV light source to attract insects and a protective grid to prevent accidental human contact with the live wires.
