If a light or set of lights is able to be switched 'on' and 'off' by more than one switch then those switches are 3-way switches. 3-way switches will have 3 screws on the sides for terminating wires as opposed to 2 screws on a regular single pole switch. 3-ways will typically have 2 brass screws and one black screw called the 'common'.

A three-way switch has three positions: off, on, and on in a different location, which allows the circuit to be controlled from two different locations.
Wiki User
∙ 14y agoA three way switch is considered to be a single pole, double throw switch. There will be three terminals, not counting the ground terminal.

∙ 12y agoNo... you need a 3-way switch. A double pole switch is used when you are turning on and off something that requires 220-240V.

Why do they call a three-way switch when it isn't?
The switch operates from two locations, such as upstairs and downstairs, but there are three ways it can be set: both switches "on", both switches "off", or one switch "on" and one switch "off".
A three way switch is what type of switch?
A three way switch is one of two devices that is used in operating a load from two different positions. This type of electrical circuit is known as three way switching. This terminology is used in North America, in Europe and the UK this type of switching is known as two way switching.
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.
Why won't a three way lamp switch work on all three settings when used in a outlet controlled by a wall switch?
A three-way lamp switch requires a dedicated three-way bulb and socket to function on all three settings. If used in an outlet controlled by a wall switch, the voltage may not be appropriate for all settings to operate correctly. Additionally, the wiring configuration in the wall switch setup may not be compatible with the three-way lamp switch.
How can you tell if the switch that you have is a 3 way or not?
You can tell if a switch is a 3-way switch by looking at how many terminals it has. A 3-way switch will have three terminals, including a common terminal and two traveler terminals. It is designed to control a light fixture from two separate locations.
What are the common three pickups positions on a guitar with a three-way switch?
Three way with two humbuckers is: up position = neck middle position = both down position = bridge Three way with three single coils is: up position = neck middle position = middle down position = bridge
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.
What is a 3-way switch?
A three way switch is a switch that is used in a lighting circuit that allows the light fixture to be turned on from three separate locations within the building. In electrical terminology this switch is also referred to as a SPST, Single Pole Single Throw switch. The switch has three individual terminals of which two are always connected. These switches are usually located at the far extremes of the circuit with an intermediate switch between them. This intermediate switch is referred to an a four way switch.
What is a 3 way switch?

Where can you buy 3 way switches in Pittsburgh?
There are several places that store three way switches for selling in PA. Some local ones are these: Kitchen Distributors of the North Hills, Sandfree, Kitchen Switch and Switch Three Way.
Can you connect one single light switch to another single light switch to control the same light on or off.?
Yes you can. There are three ways of doing this. Two are incorrect and one is the correct way of doing it.The two switches can be paralleled together to make the light fixture respond. Both of the two switches will always have to be in the on position. Either switch will turn the light off but the second switch will not turn the light on. Very inconvenient when you enter a room through one door and leave by another.The two switches can be wired in series. Both switches have to be on to operate the light but again if one of either switch is left in the off position the other switch will not operate the light fixture. Very inconvenient when you enter a room through one door and leave by another.The correct way of wiring two switches to control a central light fixture is with a three way switching system (two way in the UK). The two positions have to have special three way switches in each position. These types of switches sort out the problems of leaving a switch in a certain position to operate properly. The only criteria is that there be a three conductor cable joining the two three way switch boxes together.See related links below.
How do you wire a 2 way light switch down stairs to a 1 way switch up stairs?
You don't. You use a pair of two-way switches ('three-way switches' in US/Canada).
Can you hookup more than two four way switches between three way switch?
Yes you can hook up as many as seems fit to turn on and off fixtures from many locations. Just keep in mind the three way switches have to start and finish the combinations to keep the circuitry legal. No switching neutrals There are other systems that switch the neutral wire which in North America is against electrical code rules.

Has there ever been a switch handed pitcher?
yes there was a switch pitcher and his name was pat venditte on the new york yankees and you could switch the way your batting even if your not a switch hitter cause many people say it would not be fair that the pitcher can switch hands and most of the batters aren't switch hitters so they can only switch sides three times and then they had to stay where they are even if they're aren't a switch hitter
Do you have more direct control over accuracy or precision?
You have more control of accuracy because you can switch positions or look at it a different way to make your guess, or hit your target.
