In a theoretical ciucuit, a switch is not essential. What is needed is a source of electricity.
to make a torch you need batteries (obviously), a switch (you can buy a standard switch or make a pressure switch out of foil and cardboard), a light bulb, wires (3 if you are using any kind of switch) and a housing (something to hold the batteries, wires, light bulb etc. together). I would also recommend using a light bulb holder and wires with alligator clips (if you dont have solder) as these make the construction more sturdy. they may increase bulk but they are worth it especially as it is easy to replace the bulb and there is no solder needed therefore nothing has to be broken to replace anything.
switch lights off
To build your own light using simple materials and tools, you can start by gathering a power source like a battery, a light bulb, wires, and a switch. Connect the wires to the battery, switch, and light bulb in a circuit. Make sure the connections are secure and the circuit is complete. When you turn on the switch, the light bulb should illuminate. Be cautious when working with electricity and always follow safety guidelines.

You can make music come on with a light switch the same way you can make a light bulb come on - plug a radio into the switched outlet.

To make light bulbs glow dimmer, I reduced the amount of electricity flowing to them by using a dimmer switch or a lower wattage bulb. This decrease in electricity causes the filament in the bulb to emit less light, resulting in a dimmer glow.

When choosing a light bulb for a dimmer switch, make sure to select a bulb that is labeled as "dimmable" to ensure compatibility. Additionally, consider the type of dimmer switch you have (e.g. incandescent, LED, or CFL) and choose a bulb that is compatible with that type. It is also important to check the wattage and voltage requirements of both the dimmer switch and the light bulb to ensure they are compatible.
Using a remote control similar to those ones used to turn on electronic devices. The infrared rays can switch the light bulb on, since it has a small transistorised circuit that can actuate a tiny relay to put the light bulb in series with the electric circuit.

When you flip the switch on a flashlight, it completes the circuit and allows the flow of electricity from the battery to the light bulb. This causes the filament in the light bulb to heat up and produce light through a process called incandescence.
