Micro switches play an important role in controlling lighting in microwave. It can automatically control the switch of the lighting system according to the opening and closing state of the microwave door, providing better visual effects. When the microwave oven door is opened, the microwave micro switch will connect the circuit, so that the lighting system will be turned on, which is convenient for the user to observe the condition of the food.
