The diagram illustrate the internal structure of an LED (light emitting diode) and and explain how it functions in both the on and off position.
Overall, the flashlight consists of five main components and its operation relies on batteries acting as the power source and electric circuit that can be opened or broken through using slide switch.
As we can see at the external structure of the flashlight, it includes plastic case and an LED bulb placed on the top that emits light when being powered. Meanwhile, the slide switch is installed on the side to control metal swich contacts. In addition, two batteries are placed inside to act as the power source. At the bottom of the flashlight also puts a metal spring that can enable flow of current to generate electricity upward.
Additionally, when the slide switch is on position, it allows metal swich contacts to connect. This enables electric current flow from batteries through a metal spring to the LED, making it emit light. In contrast, when the slide switch is turned off, the metal swich contacts are disconnected that break circuit and prevent the flow of current. Therefore, the LED remains off.
