Your 2 switches will have 3 terminals each. One will be copper colored and two black.

You will require a 12-3 WG wire between the switches.

The Travelers: The black terminals will be connected together one from switch a to switch b and the other from switch a to switch b, it does not matter which black terms you choose to go from switch a to b

The brass terminals one will go to the light switch a and the other to a power source switch b.

I have trouble understanding your question. But I think you are saying that you have two switches that control one light and want to know why it is not working. More than likely is that you have two way switches instead of 3 way switches installed. 3 three switches cost a little more and are a little more difficult to install but if you recently replaced these switches you may have replaced them with the wrong type.

Send an e-mail with your request and I'll send you a diagram.

That is called a 4 way light switch circuit. On each end of the circuit you install a 3way switch and in the middle you install a 4 way switch.Answer using British TerminologyIn the UK, 'three-way' switches are called 'two-way' switches (more logical, if you think about it!), and the 'four-way' switch is called an 'intermediate' switch.

Three-way light switches come with a wiring diagram on the package.

Two three way switches are used when wiring a three way switch installation.

There are hundreds of type of switches. In residential homes there is basically 4 types of switches used. Single Pole, 3/Way, 4/Way (intermediate), or various types of dimmer switches.

Yes. the two switches are called '3-way' switches. You will have to turn the fan/light on with one of the switches and leave BOTH switches in that position. The remote control unit will have to be wired in between the switch that is supplying power to the devices and the devices. This is the simplest way. You could also disable one of the switches and replace the remaining switch with the RC unit. If you are not sure how to deal with 3-way switches, learn about them first, or call a good electrician to do all of the work. Remeber that the black wire is hot, but only if the house was wired properly in the first place.

A 3 way wall switch is used in a circuit for two switches that can turn a light fixture on or off from two different locations. Both switches must be 3 way switches. For more information see the answers to the Related Questions shown below.

You use two 3-way switches. You can find the wiring diagram using Google and look for 3-way switch wiring.

There is no way to safely 4 lights to 3 switches. You can however complete this process by splitting wires.

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'.

3 way switches have 3 terminals. A common on and off switch only has 2.

The two wires that travel between two three way switches are called travelers.

No. A double pole switch would be a switch that switches 2 different loads simultaneously. 3-way switches (and 4-way switches if more than 2 are used) are what are used for controlling a light from multiple locations. While a typical single pole switch simply opens or closes a single contact, a 3-way switch provides a path from a contact point to, let's say, point A or point B. Points A and B from the first 3-way switch are connected to points A and B of the second 3-way switch and then the common contact point of the second switch is connected to your light. When more than 2 switches are desired, you can use any number of 4-way switches between the 3-way switches, but the 3-way switches MUST be on the ends of the circuit.

Yes. Instead of sending the hot wire straight from one of the three way switches to the light, put a dimmer switch on the hot wire to control the light.

If I am reading your question right, you can do this. Just parallel the outlets to the device already switched by the 3-way switches. The outlets will turn off and on by the switches. Watch that you do not overload the switches or the circuit.

In the mansion the marowak switches are on levels 2,and 3.(you are pobaly gonna get attacted along the way.)

User Avatar

I believe you'd have to use a standard set of three way switches and a contactor. Tie the 120 volt coil to the three way switches and the 220 volt contactor to the load.Unless your talking about a 277 volt load, then you can use 277 volt switches.Use a relayYou're probably better off trying to wire a separate 3-way switch circuit (at 110 or even 24 vAC) to control a heavy-duty relay that operates the 220-volt device.

Yes, because the light is using 3-way switches. There is always "power" travelling between the switches.

You need a wire that u can link to 3 ways then link them to 3 light switches anywhere in your house the farther the more.

User Avatar

You will need two 3/way switches and two 4/way (Intermediate) switches. Click the link to see a video of exactly how to wire such a circuit.

It is a switch that disconnects one wire from one other wire, with a handle that is in one of two positions (i.e., on or off). There are also 3-position switches (not to be confused with "3-way" switches that only have two positions), push-button switches, twist or chain-pull switches, etc, all for a single pole.

User Avatar

are the three switches all together in one box? Is there a 3 way switch involved?

User Avatar

You need three wires and ground between switches and a pair for supply and one for load. Google 3-way switch wiring for a diagram.

Most of the time, there are two types of pickup selector switches apparent in electirc guitars, 3 way and 5 way switches. 3 way switches are usually used for guitars with a HH (2 humbucking pickups) configuration, while 5 way switches are usually used for guitars with an SSS or HSS or HSH (3 single-coil pickups or 1 humbucker and 2 single-coil pickups or 2 humbuckers and 1 single-coil pickup) configuration. There are exceptions, however. For example, on many PRS guitars with a HH configuration you may find a 5 way rotary switch that allows more versatility than a 3 way switch.
