The given diagram analyzes the findings of a led (light-emitting diode) to explore its internal structures and functions of each part.
Overall, the led has five distinct parts in which batteries take the role in providing energy for the light bulb and the slide switch controls the process.
Looking at the external shapes, the plastic case takes a role in a protection covering all other parts of the led. On the left side of the outside cover, there is a slide switch which can be used as a control to ignite the light by pushing up to turn on the light and pushing down to cut off the electricity and turn off the light.
Regarding the internal parts, behind the slide switch is a mental switch contact taking a role as a bridge in transporting electricity to the light. There is a bronze line to transfer electricity. At the bottom of the led is a mental spring which is utilised to pull the energy resource- the batteries to touch the light and provide lighting.
