The internal lighting of the refrigerator is made by an incandescent lamp of low power and sufficient to make visible the products inside the refrigerator.
In Brazil, lighting is used only to visualize the product inside the refrigerator. In other countries, in addition to the illumination lamp, a special type of lamp is also used whose rays have a germicidal effect, eliminating bacteria and fungi.
Lamp operation occurs through the switch installed near the refrigerator door.
Every time the door is opened, the switch closes the contact and turns on the light. And every time the door closes, the switch opens the contact and turns off the light.
