The different way to connect Two-Way Switches.
You may know the connection of Two-Way switches. But in this post, we are going to show the different way of two-way switch connection. Before going to the explanation you must know that this connection not suitable at home or working places. Because during the operation phase and neutral of the bulb will interchange. See the below circuit diagram and make the circuit diagram.
What is Two Way Switch Wiring : Circuit Diagram & Its Working
A switch is an electrical device that controls the flow of current in a circuit. Every electronic and electrical application uses at least one switch to perform on and off operation of the device. The switches are further classified into two types they are electrical switches and mechanical switches. The one-way (single-pole), two-way (double-pole) are the two types of an electrical switch. The two-way switch is used to on/off the light, fan from two different locations. This article discusses the two-way switch wiring function, working, and circuit diagram.
What is a Two-way Switch?
The two way (double-pole) switch is used to ON and OFF the light from two different locations and the switch is mostly used in the case of stairs, in rooms that have two entries. This type of switch is generally used in some home wiring systems and industrial applications.
Two Way Switch Wiring
The COM, L1, and L2 are the three terminals of the two-way switch. The L1 terminals of both the switches are connected to phase, and L2 terminals of both the switches connected to one end of the bulb terminal and the other end of the bulb terminal are connected to neutral of the AC supply. The three-wire two-way switch wiring diagram is shown in the below figure.
The configuration of the three-wire two-way switch wiring is similar to the EX-OR gate in terms of digital electronics.
| S.NO | Switch 1 COM | Switch 2 COM | Light |
1 | L1 | L1 | OFF |
2 | L1 | L2 | ON |
| 3 | L2 | L1 | ON |
| 4 | L2 | L2 | OFF |
The light is OFF when COM terminals of both the switches are connected with L1 or L2 terminals. The light is ON when the first switch COM terminal is connected with the L1 terminal and the second switch COM terminal is connected with the L2 terminal. Similarly, the light is ON when the first switch COM terminal is connected with the L2 terminal and the second switch COM terminal is connected with the L1 terminal. This is the function of two way switch wiring.
The two-way switch front and the back view is shown in the below figure.
