In this tutorial, we will show you how to make 2-way switching connection. We have explained both the methods below and both the methods are demonstrated in the Video given at the end of this article. This is the first method to make a 2-way switching connection, this is the old method. If you are going to install a new one then go for three wire control method.
Three-way switches require a three-wire cable: The cable should also have a ground wire, or a total of four wires in the cable. The system also requires three-way switches. The switches are wider than regular single-pole switches and they have three terminal screws on the side sometimes back of the switch housing. Two terminals will be on one side of the switch housing; one terminal on the other side. Four-way switches have four terminals.
Definitions of terms: The hot wire from the breaker usually black Neutral: The return wire for circuits usually white Load: The wire that will be hot when the circuit is completed to your light usually black Traveler: In existing 3-way wiring, this wire toggles hot between two switches.
Here is a two way switching solution posted for one of our users who had run the power feed to one of the switch boxes and had no radial circuit to pick up a neutral at the lamp holder. Two way switching with power feed to the switch. If you are doing a new install or replacing a two way switch system go for the three wire control method. Fig 1:
