Furthermore, pressing an external button allows for control... The controller 7 sets and controls it. Then, when the temperature sensor 8 senses that the temperature of the multilayer PCB printed circuit board body 2 is high, the cooling fan 404 starts to work, and the geared motor 406 rotates accordingly.
