The diagram illustrates the working system of light emitting diode (LED) flashlight.
Overall, the LED flashlight contains seven elements, beginning with a slide switch and culminating with an LED bulb positioned at the top. Also, all components are situated inside a plastic case.
The device involves a slight switch outside the case where users are able to turn on or off. At this point, when the LED is switched on, the mechanism shifts the metal switch contacts to the electric circuit. Subsequently, this process allows the current to flow through the metal switch contacts, a metal spring to LED batteries. After metal contacts are switched, the metal spring pushes the batteries under the pressure to connect the LED lamp.
In contrast, if the LED is in an “off” position, the electrical circuit breaks in order to detach the mechanism. As a result, the energy from batteries will be cut off and the bulb will not emit the light.
