Brilliant Wiring Two 3 Way Switches Double Pole Light Switch Diagram

Before you begin wiring 3 way switches you must understand this in order for you to have a three way circuit you should have three way switches. First run a 2 wire cable from the wall power to the black screw on 1 of the switches. A 3 way switch allows you to turn a light on or off from two different switches. Turn off the correct circuit at your electrical panel. Wiring 3 way switches is not complicated but making sure you are connecting the right wires could be a little tricky. Wiring a 3 way switch isn t that difficult. This is the 3 wire cable which you must have to wire a 3 way light switch. Pick the diagram that is most like the scenario you are in and see if you can wire your switch. 3 way switches are useful for large rooms with multiple entrances but require a bit more wiring than a standard single pole switch. The wiring method will depend on whether your power goes to the switch first or the light first.

Then connect the 2 switches by splitting the 3 wire cable apart and attaching each of the 3 wires to one of the other 3 screws on each switch. Finally run the last 2 wire cable from the second switch s black screw to the light. If you are going to install a new one then go for three wire control methods. Wiring 3 way switches is not complicated but making sure you are connecting the right wires could be a little tricky. A 3 way switch allows you to turn a light on or off from two different switches. 3 way switch wiring diagram. First run a 2 wire cable from the wall power to the black screw on 1 of the switches. This method is depicted in the diagram at the top of this post. 3 way switches are useful for large rooms with multiple entrances but require a bit more wiring than a standard single pole switch. This is the 3 wire cable which you must have to wire a 3 way light switch.

Wiring 3 way switches is not complicated but making sure you are connecting the right wires could be a little tricky. The answer to how it works is to have an extra hot wire that runs between the two switch boxes. So what you should see if you have correct 3 wire electrical cable romex is a black power white neutral and now a 3rd red wire. In one position the com and l1 are connected while in the second position the com and l2 are connected. A three conductor cable with a ground is then installed between the two 3 way switch boxes. This is the first method to make a 2 way switching connection this is the old method. Finding three way switches to purchase isn t hard in. If you are going to install a new one then go for three wire control methods. This is where diagrams come in handy and we are including them below along with step by step wiring instructions in the video format. This method is depicted in the diagram at the top of this post.

The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used. It s likely you ll also need to replace the existing switch box with a larger one to accommodate the extra wires for the 3 way switch. First run a 2 wire cable from the wall power to the black screw on 1 of the switches. It is a standard single pole switch with three terminals. This is the 3 wire cable which you must have to wire a 3 way light switch. Finally run the last 2 wire cable from the second switch s black screw to the light. The wiring method will depend on whether your power goes to the switch first or the light first. A three conductor cable with a ground is then installed between the two 3 way switch boxes. This might seem intimidating but it does not have to be. Then connect the 2 switches by splitting the 3 wire cable apart and attaching each of the 3 wires to one of the other 3 screws on each switch.

Regardless of what 3 way switch wiring diagram you re following you ll need to use a 3 wire cable to connect the two 3 way light switches. Pick the diagram that is most like the scenario you are in and see if you can wire your switch. Take a closer look at a 3 way switch wiring diagram. Either way complete these five steps for 3 way light switch wiring. As you see in the 2 way switch diagram below you will find that the phase live is connected with the common of the first 2 way switch. In one position the com and l1 are connected while in the second position the com and l2 are connected. This is where diagrams come in handy and we are including them below along with step by step wiring instructions in the video format. This might seem intimidating but it does not have to be. Pin1 pin2 of the first switch are connected with the pin1 pin2 of the second switch respectively. Before proceeding an important component called a two way light switch is the main element of the 2 way switching irrespective of the type of wiring used.
