The diagram depicts the design and operation of an LED flashlight. Overall, the flashlight comprises three core elements: a protective outer casting, a power supply and switch mechanism directing the electric circuit.
As can be clearly seen from the diagram, the layout of the LED torch is intricately structured.It is pronounced that the entire device is enclosed in a plastic enclosure, which can be regarded as a protective layer. Internally, there exist two batteries arranged in vertical layout and functioning as a main power source. Moreover, the negative terminal is attached to metal spring with a view to assisting the flow of electric current through the device
Regarding the working principle, the compact LED torch functions via a slide switch, enabling the user to regulate the electrical current. Only after the switch is pushed into the on position do the metal switch contact close and the circuit is completed, thereby activating a flow of energy and the light turns on. By contrast, in the off position, the switch is pushed downward, separating two contacts. As a result of the prevention of current from reaching the bulb, the flashlight is turned off
