When the switch of a flashlight is pushed into the ON position, it makes contact between two contact strips, which begin a flow of electricity, powered from the battery. The batteries are connected in such a way that electricity (flow of electrons) runs between the positive and negative electrodes of the battery.

Explanation:
A torch is a practical example of a simple electric circuit. It is an electric device that emits light. It consists of a bulb, electric cells, a switch, a reflector, and a cylindrical shape casing.
Function of each component of a torch
Bulb: The bulb emits light when electric current flows through its filament.
Electric cell: The cell is an electricity-producing device. The required current for the filament of the bulb is supplied by it.
Switch: The switch is used to complete and break the circuit inside the torch. In simple words, it is used to turn the torch on and off.
Reflector: The reflector is a curved, silvered mirror. It is used to focus the light in a particular direction.
Casing: The casing is used to provide covering for the basic components of the torch for protection and safe handling.
