All a switch does is make and break the supply of electricity to the lamp.
If you get a chance to visit a science museum ask them to show you a "knife switch". Another place to see one is the Physics Lab at your local college or high school. Once you have seen a knife switch you will understand exactly how a basic switch works. It's quite simple really: a switch is a device which can be used to make or break a circuit. If that circuit carries a voltage which would be dangerous to people or animals then the handle of the switch must be made of a good insulator and the rest of the switch must be well shielded to stop anything else touching any live wires.

BlakeWhen the switch is turned on, it completes the electrical circuit, allowing current to flow through the light bulb. The current heats up the filament inside the bulb, causing it to emit light. When the switch is turned off, the circuit is broken and the current stops flowing, turning off the light.

Your light has a dimmer switch on and the light wont work?
If the light has a dimmer switch and it's not working, first check if the dimmer switch is in the correct position and hasn't been accidentally turned off. If the switch is on and the light still isn't working, there may be an issue with the dimmer switch or the light bulb itself. Try replacing the bulb or checking the dimmer switch for any malfunctions.
A light bulb is hanging in the first floor of the room There are three switches in the ground floor room One of these switches belongs to that light bulb The light bulb is not lit and the switches?
Turn on one of the switches and leave it on for a few minutes. Then turn it off and turn on another switch. Proceed upstairs and touch the light bulb. The bulb that is warm corresponds to the switch you turned on first, and the bulb that is off and not warm corresponds to the switch you turned on second.
Why won't a three way lamp switch work with a wall controlled outlet?
A three-way lamp switch is designed for controlling the brightness of a three-way light bulb, not for controlling an outlet. A wall-controlled outlet typically has a simple on/off switch mechanism, which is different from the dimming functionality of a three-way lamp switch. They are not compatible due to their different functionalities.
How do you connect a switch to a light then another light to a switch and have the switch work only the light on its end?
go to the Help option in Matlab. It will not help at all.
When you flip a switch to turn on the light you?
complete the electrical circuit, allowing electricity to flow from the power source through the light bulb, causing it to illuminate.
