It provides the light in the torch
when you switch on the torch you will see that the torch has light
the switch in a torch allows the circuit in the torch to be completed
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
To switch on a Rolson mini torch, locate the power switch, usually found on the side or back of the torch. Slide or press the switch to the "On" position. If the torch has multiple brightness settings, you may need to cycle through them by pressing the switch again. Ensure the torch has working batteries for it to function properly.
A torch is simply a circuit containing a battery, a bulb and a switch. The three components are connected in series (one after the other) to form a loop. The switch simply completes the circuit so that power flows from the battery to the bulb.
my torch does work though...

A torch is simply a circuit containing a battery, a bulb and a switch. The three components are connected in series (one after the other) to form a loop. The switch simply completes the circuit so that power flows from the battery to the bulb.
In a torch (flashlight), the current passes from the positive terminal, through the bulb, and returns back in the negative terminals, making a complete circuit. When the switch is moved to the on position, a metal piece inside the case touches the positive terminals of the battery, the circuit is completed, and the torch turns on. Move the switch to the off position, the metal piece no longer touches the positive terminals of the battery, and the torch turns off.

The job of a bulb is to give off heat and light energy
