The diagram illustrates how a flashlight is made and how it works.
Overall, the flashlight consists of three main components: a protective outer case, a power supply, and a switch mechanism that controls the electric circuit.
Regarding its structure, the flashlight is in a plastic case with a slide switch and metal switch contacts, which are used to turn the device on and off. Inside the case, two batteries are positioned vertically. The terminal of the lower battery is connected to a metal spring, which helps facilitate the flow of electric current through the device.
Considering how it works, its operation depends on the position of the slide switch. When the switch is pushed down to the “Off” position, the circuit is broken, meaning no current can flow through the circuit to activate the light. By contrast, pushing the switch upward completes the circuit, allowing the electricity to pass through the batteries and power the LED, producing light.
