Hey, in this article, we are going to see the wiring diagram for a lighting system in a corridor or a hallway. The lighting system is designed in such a way that the light can be controlled from two places using special switches called 2-way switches.

For example, if a hallway has a light in the middle position and switches at both ends. You can turn the light ON or OFF from either end. When you come into the hallway, you can turn the light ON with one switch. Then, when you go to the other end of the hallway, you can turn the light OFF with the other switch. This is useful because you can control the light from different places.

As we know, the hallway or corridor is a very large place so we need to install so many lights and each light can be controlled by two different places.

## Wiring Diagram

Here you can see the wiring diagram for the lighting system in a corridor.

Here, we have used only three lights to simplify the wiring diagram. If you need more lights you can add more lights in the same way as shown in the above diagram.

## Connection Procedure

1. Connect the neutral terminal of all the lamps to the neutral terminal of the power source directly.

2. Connect the upper and lower terminals of both Two way switches together that are used to control the same lamp. For example, here in the above wiring diagram, you can see that Switch 1 and Switch 2 are used to control lamp 1. So, the upper and lower terminals of both switches are connected together.

3. Now connect the common terminal of the first two-way switch to the phase terminal of the power source. And connect the common terminal of the second switch to the phase terminal of the lamp.

4. Following the same procedure connect all the lights and their respective two-way switches.

## Operation

Let's assume as per the above wiring diagram, the lights are installed in the middle of the corridor and switches are installed on two side walls.

1. When the person just enters the corridor and presses Switch 1 the light 1 will turn ON.

2. The person moves forward and presses switch 3, light 2 also be turned ON.

3. The person again moves forward and presses switch 5, light 3 also be turned ON.

4. Now the person reaches the end of the corridor and wants to go return to the outside using the pathway of the right side wall.

5. When the Person presses switch 6, light 3 will be turned OFF.

6. When the Person presses switch 4, light 2 will be turned OFF.

7. When the Person presses switch 2, light 1 will be turned OFF.

8. So all the lights will be turned OFF when the person leaves the corridor.

Here, we have only one example. The person can operate the switches as their requirements. Just remember the main key point that when the person presses the switch the current state of the Light will be changed. If the light is in OFF condition then it will be turned ON and Vice Versa.
