What is the correct connection for this ground wire?Īnswer: As explained in this page above: These Type-NM cables contain a ground conductor which is required for all applications as well. To control any AC appliances like fan or light from two places like entry and exit.Question: Your example shows 2 wire Romex but most Romex I have seen has three wires one white-one black and an un-shrouded copper ground wire.Erroneous tripping of safety/circuit protection equipment.Where 0 represents the OFF condition and 1 represents the ON condition. The condition of getting Output in ON condition is the same as the Ex-or gate truth table which is given below:
Note: In the 3-wire control method when switches are in the same state the light will be in OFF state as shown in the circuit below: PIN1 of both the switches are connected with the phase or live wire and PIN2 of both the switches are connected with the one end of the lamp. The other end of the Lamp is connected with the Neutral line of AC power supply.
This method is commonly used nowadays as it is efficient than the Two-Wire control system.Īs you can see in the Schematic Diagram of 2 way switch circuit below, the common of both the switches are short-circuited. This is the new method to make a 2-way switch connection and it is slightly different from the two-wire control method.

How to Connect 2-way Switch Wiring using Three-wire control Where, 0 represents the OFF condition and 1 represents the ON condition. The condition of getting Output in ON condition is the same as the Ex-nor gate truth table which is given below: Note: In the 2-wire control method when switches are in an opposite state the light will be in OFF state as shown in the circuit below: One end of the bulb is connected with the Common Terminal of the second switch and another end of the Bulb is connected with the Neutral line of the AC power supply. PIN1 & PIN2 of the first switch are connected with the PIN1 & PIN2 of the second switch respectively.

If you are going to install a new one then go for three wire control methods.Īs 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. This is the first method to make a 2-way switching connection, this is the old method. Required Components for Two Way Switch ConnectionĢ-way Switch Wiring using Two-wire control We have explained both the methods below and both the methods are demonstrated in the Video given at the end of this article. There are two methods of making 2-way switching connection one is 2-wire control and another is 3-wire control. Two way switch can be operated from any of the switch independently, means whatever be the position of other switch(ON/OFF), you can control the light with other switch. A 2-way switching connection means you can control electrical equipment like bulb by two switches placed at different places, generally used in the staircase. But in this tutorial, we will show you how to make 2-way switch wiring with normal household switches. Now, there are many different types of switch in the market, and few of them directly be used for two way connection without any special two way wiring connections.
Staircase lighting at home or at any other place for that matter is normally done with something called a two way switch. Perhaps most of us might have already used it without paying much attention to how it works. One of the simple yet interesting connection diagrams that young engineers learn in their lab is the staircase lighting connection set-up.
