You need two 3-way switches. To see a diagram use your favorite search engine and search for 3-way switch wiring. Each switch has a common connection point and two other terminals. Basically connect the "other" terminal on 1 switch to either "other" terminal on the second switch and then do it again for the remaining "other" terminal. Then connect the common on one switch to the fixture and the common on the remaining switch to supply voltage. Tie neutral and ground for fixture and supply to the white and bare wires respectively.

How do you connect a 3 wire fixture to a 2 wire fixture that are connected to the same switch what do you connect the red wire to?
A three wire fixture most likely is one that has two separate loads within it. An example is a ceiling fan with a light fixture. If the three wire is used to separately switch the two loads you have to make a decision as to which load you want to work with the two wire fixture. Once that decision has been made connect the two wire fixture in parallel with the your selected load on the three wire fixture. On these types of installations the three wire fixture is usually controlled by two separate switches in a two gang box. The red and black wires of the three wire terminates on the bottom of either switch. The white wire is connected to the incoming neutral. The top of the switches are paralleled together with the "hot" feeder from the distribution source.
How do you add another porch light to an existing switch?
Piggyback off the box for the existing light. Run a wire from the existing junction box to a new junction box (which is placed wherever you want the new fixture). Then, in the existing box, connect the wire coming from the switch, the wire for the existing fixture, and the wire for the new fixture together using wire nuts. Wire up the new fixture, and presto, you have two fixtures on a switch where there was only one before.
Can you use 14-2 wire to operate a ceiling fan using two switches one for the fan the other for the lights?
On these types of installations an electrician would use a three wire cable set from the switch box to the fixture's junction box. At the fixture's junction box both the fan neutral and the light neutral would be wire nutted together with the incoming neutral from the switch boxes. From the three wire, the white wire would go to the fan and light's neutral wires. The Black would come from the bottom of one of the switches and go to the fan's motor lead. The red wire would come from the bottom of the other switch and go to the light fixture's lead. It can be done with two runs of two wire to the fixture. You will need a two gang switch box for this project to hold the two separate switches. You could use a single gang light switch box if you can still find where duplex switches being sold. A duplex switch is one that has the configuration of a duplex receptacle with the switches being one on top of the other. The cover plate is the same one used for duplex receptacles. To answer this question fully more information is needed. See discuss in the left margin.
Why do you use two switches to turn on a lamp instead of one switch?
When there's two switches connected to the same lamp it's usually because the lamp was meant to be able to be turned on and off from two different places. Useful in corridors and stairs and places like that. Or it can be that it originally was a fixture with more than one bulb in it. Two switches meant you could get different amounts of light out of the same fixture.
What is single pole two way switch?
It provides switching for a single wire. It has one input and one output. When the switch is open (Off) the input is not connected to the output. When it is closed (On) the input is connected to the output.
How do you wire in a pull chain switch in a bathroom light fixture?
If you are adding the pull chain to an existing fixture then the pull chain switch should have two wires. Wire nut either one to the hot wire coming in and the other to the black wire of the fixture.
Outside porch lamp has no box just two wires coming in black wires are tied and don't connect to fixture just the white wires what is going on here?
You would have to provide more info to be certain what your problem is. Typically a black and white wire would connect to the two wires on the light fixture. The fixture should also be controlled by a switch that "breaks" the black (Hot Wire) to turn off the fixture. If you have a volt meter you can see if there is 120Volts between the black and white wires with switch on. If there is a single white wire going to fixture (Neutral), where is the "black wires tied" to. Maybe one of the black wires has broken off the fixture.
How do you connect a White Black Green wired device to household White Black Red ground light outlet?
If there is a red wire in the fixture box it sounds like the fixture is three way switched. The travelers are coming from one of the two switches and the cable is going to the second switch.See related links below.
How do you wire a ceiling light from five different locations?
=== === In the ceiling box there may be a Black wire, a Red wire, a White wire and a Green or Bare wire. The light fixture may only have a Black wire, a White wire and it may or may not have a Green or a Bare wire.The Black wire in the ceiling box may or may not be be a "Hot traveler" wire coming from the lighting circuit breaker on the main panel. The Red wire may or may not be a "Switched Hot" coming from the light switch for this light. The White wire should be a Neutral coming from the main panel. The Green wire should only ever be a safety Ground wire coming from the main panel.Or there may be a two-way switched circuit feeding the light. If it is a light near some stairs and you have 2 switches controlling it, one switch downstairs and another switch upstairs, then the wiring could well be as follows: the Red (or the Black) is a "hot feed" to the switches and the other one, the Black (or the Red) is the "hot return" from the switches. (There would also have to be a further wire, a "Hot Common" wire running between the switches which could be any color other than Green or Bare and it may or may not appear in the ceiling box, it depends where the switches are located.)The light fixture must be hooked-up as follows:If the light fixture has a Green or Bare wire it must be connected to the Green or Bare wire in the ceiling box. (On European fittings the Ground or Earth wire is Yellow/Green.) If the Neutral on the light fixture is a White wire it must be connected to the White wire in the ceiling box. (On European fittings the Neutral is a Blue wire.) If the Hot on the light fixture is a Black wire it must be connected to the switched hot wire in the ceiling box, which may be Red or it may be Black: you must check which wire is the correct one to use or the light will not be switched off by the switch! (On European fittings the Hot or Live is a Brown wire.)For more information see the answer to the Related Question shown below. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Have a bathroom light that is wired hot at all times how do you wire a pull chain up to it?
This sounds very strange. You should not have an unswitched bathroom light. Replace fixture with one with a pull chain. Turn breaker off before changing the fixture.
What is difference between single pole and double pole switch?
A single pole switch interrupts only one wire, which must be the live wire. A double pole switch interrupts both the live and the neutral, so it contains two separate switches operated by the same lever. Current practice is to use single-pole switches, to avoid a fault condition which could leave equipment live while switched off.
How do you repair a pull chain switch on a fluorescent light?
Shut off the breaker that supplies the voltage to the fluorescent fixture. Wire the new pull chain switch in series with the black incoming wire and the black wire of the ballast. Turn the breaker back on and your switch will now control the off on operation of the light fixture.
