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.

Why won't a three way lamp switch work with a wall controlled outlet?
Not wanting to state the obvious but the wall switch has to be turned on to supply voltage to the outlet. The lamp will need a three way light bulb in the lamp. A three way bulb uses two filaments of different lengths. One element is used for low brightness, the other filament for medium brightness and the high brightness setting uses both filaments in the bulb. If a single filament ordinary light bulb is used in place of a three way light bulb there will be a position on the three way lamp switch where the bulb will not light. Find the position on the lamp where the bulb will light and leave it there. Use the wall switch to turn the lamp off and on through the controlled receptacle.
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?
All the switches to be tried first. 2 out of 3 must be switches of the ground floor room. So which ever doesn't work for the ground floor electronics must be first floor bulb switch J
Why do shower lights go off?
Assuming you are mentally sane and not on meth, try tightening the bulb. If that does not work, it culd be a loose connection in your switch. DO NOT try to fix this if you don't know how. Get help. And if it's not any of those, then your house is haunted. Get help.
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.
If you unscrew a light bulb slightly and leave the power on to it is it still using power?
Possibly. If it still works when you turn it on, the of course it is using power. If it does not work when it otherwise would, then it is definitely not using power, just as if you didn't have the bulb there at all. <<>> With the voltage on the circuit and the light bulb in the circuit, the bulb will glow. If you unscrew the bulb until it goes out the potential voltage will still be in the circuit but no current will flow so no power will be used. In this scenario the unscrewing of the bulb will be the same as using a switch in the circuit to interrupt the current flow.
What could cause a light switch not to work?
water, power outage, or maybe the light bulb is broken
Why will a bulb not light if a switch is open in a circuit?
It will not work because it has to be closed so the electricity can go to the bulb.
What circuits are closed paths that will allow electricity to travel in a loop and make a light bulb work?
a switch
Why your turn signal and your tail lights dount work is not the bulb?
Defective stop light switch or fuse.
How does a battery powered light work?
The battery chemically stores electricity so when you 'switch on' the light then electricity flows from the battery to the bulb. The bulb the heats up to glow white and the reflector shines the light out of the battery powered light
What did Einstein do 100 times to get it to work?
To build the light bulb.
Why will glove box light not work on 2002 Subaru Outback Wagon?
check the switch! then check the harness to the bulb/switch make sure you have a power and a ground
Why does my 1998 Camaro signal light not work?
Bad bulb? Blown fuse? Bad signal flasher? Bad switch?
How does a fridge light work?
Refrigerator Light OperationThe light inside a fridge is an "appliance" bulb. It is controlled by a spring loaded switch, usually mounted in the door frame across the top of the door opening.The switch is on when the door is open which allows the spring to push a "plunger" out, thus closing the switch and allowing electricity to flow to the bulb filament.When the door is closed, the door pushes the plunger IN, opening the switch, and thus cutting off the flow of electricity to the bulb.
Does a light bulb have a life span?
No, of course not. You just have to be careful not to knock it or flick the switch for it repetitively or the fuse will blow. If the fuse blows the light will not work anymore.
Does the middle bulb on the tail light work?
If there is a bulb, it should work.
Why does my 94 Oldsmobile achieva light don't work and the fuse is good?
You might need a new bulb. i had the same problem and it wasnt the bulb.. i never figured it out so i ran another switch to the lights and battery... a tuggle switch
