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.
A three way switch is considered to be a single pole, double throw switch. There will be three terminals, not counting the ground terminal.
No... 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.

Is there a residential switch 15A rating that will allow one source to be switched to either of two loads?
Yes, a three way lighting switch will do that job. There is no off position if you use this type of switch, it will be either one load or the other on all of the time. To over come this condition you can install a single pole switch ahead of the single pole double throw (three way switch, two way switch in the UK). There is a small toggle switch that has an on - off - on positions but it is not a residential switch.
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.
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 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 is the eletrical symbol for a three way switch?
If you have the symbol for a regular switch, a 3-way switch is the same symbol with a '3' next to it like a subscript.
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.
