A three way switch has three terminals: two travelers and one common. On one of the three way switches the common will be the line voltage coming in from the circuit breaker or some other device on the circuit. Two wires will travel from this switch to the second three way switch. The common on the second switch will be the wire that will feed power to the device (light fixture, motor etc.). It does not matter which of the two traveler wires go on which of the traveler terminals. If the common and one of the travelers get mixed up the switches will not work correctly. In that situation, usually one of the switches will have to be in a certain position for the other switch to work.
It is important to remember that there is also a neutral wire present in this circuit. It is separate and apart from the switches and should not be connected to them in any way.

Can a 4 way switch be used in place of a 3 way switch?
No a 3-way is a single pole double throw. A four way switch swaps travelers.
How do you wire a light switch that has a black common screw and two gold screws one on each side of light switch and a green screw?
That is called a three way switch. It's used in conjunction with another 3 way switch in another area and they both control a light or set of lights. The black is power and the other two are called travelers that wire to the the other 2 gold screws on the other switch. A three way switch can be used as a single pole switch by using the black screw and one of the brass screws. You will have to test the circuit to orient the switch so up is on and down is off, if that is what you desire, because it is not obvious on a three way switch. The green screw is simply your equipment ground. You place your green or bare conductor there.
What can be compared to a three-way switch?
a switch on railroad tracks
How can an intermediate switch be used with a 2-way switch system to control a light from four floors?
A two way switch is UK terminology for a North American three way switch. Though the switch has two names it is still a Single Pole Double Throw switch that has three terminals. North American terminology. The circuit is the same as the three way switch system. To control from four locations just add another intermediate switch. For the system to work properly the new intermediate switch has to be adjacent to the existing intermediate switch. The connections must run - three way, intermediate, intermediate, three way.
What is three way switching?
A three way switch is use control in two station of the lamp
Which terminal do you take power from on a three way switch?
USE THE 'ODD' COLORED SCREW---THE 'LIKE' COLORED SCREWS ARE USED FOR THE 'SWITCH LEGS' OR 'TRAVELERS'.
Can a 4 way switch be used in place of a 3 way switch?
No a 3-way is a single pole double throw. A four way switch swaps travelers.
How do you wire a light switch that has a black common screw and two gold screws one on each side of light switch and a green screw?

Can you replace an old no ground single switch with a three way switch?
A three way switch can be used as a single switch. Replacing this switch will not allow you to switch a fixture from two locations unless there is a three wire cable going to the second box.
Is there a way to wire a 3 way household dimmer switch as a 2 way dimmer switch?
You need a three way switch to control lights from two locations. The name is misleading. Three way switch refers to the connection points on the switch. You can use a three way switch as a single switch as long as you place hot wire on the brass screw and the use any of the other screws for the return hot.

What is a 3 gang 3 way switch?
3 gang switch and you can call it 2-way switch..is a type of swithces we are using mostly in the stairs lighting ,that mean you have switch up to the stair and one down to the stair and you can switch the light on from one and switch it off from the other switch and via verse. <<>> There is no such thing as a three gang three way switch,. The nearest thing is a three gang double throw switch. It is used to supply a three phase load from two individual three phase supply sources. This is the type of manual switch that can be used for emergency power switch over from utility to generator. Three way switching uses a single pole double throw switch at each end of the circuit and a cross over switch in the center position. The center switch in a three way lighting configuration is a cross over switch and a double pole double throw switch in that position will not work.

How do you use a 14-3 wire for Switch and Power?
you need 2 , 3 way switches on the switch you will have 3 poles 1 will be copper 2 will be silver your 1 copper is power or switch your 2 silver are travelers to toggle the power back and forth , you use the black and red wires for the travelers and use the white for the power on one switch and the white to the other to the light with your neutral ---- power---* *--------* *---switch powered *--------*
Why won't a three way lamp switch work on all three settings when used in a outlet controlled by a wall switch?
If the wall switch is on, the three way lamp switch should work. If it doesn't, it may be broken or there may be something else wrong with the circuit.
How do you wire a 3-way dimmer and switch it in 3 locations?
One 3-way dimmer switch, one regular 3-way switch and one 4-way switch. The 4-way is wired between the two pairs of travelers from the other two switches. The common on the dimmer is tied to either the light or to the branch hot and the common on the other 3-way is tied to whichever is left (hot or the light).
