How To Do Wiring For 1 Way, 2 Way and Intermediate Switch?

As for wiring for light fitting, there 3 method of switching that can be used; 1 Way, 2 Way and Intermediate Switch.

1 way is the basic of all switching method. The circuit only using single switch to control all lighting connected to that particular circuit.

2 way switch normally used for a long span of corridor, staircase, sharing toilet (with 2 doors) and room that has a two access doors.

User will have an option to switch ON or OFF the light fitting at either side of those switches. This is the advantage of using the 2 way switch compared to 1 way switch.

The other switching method is using the intermediate switch whereby more than three switches being used to control the same lighting.

These 3 types of wiring using different type of switches. Therefore, it is crucial for you to identify what type of switch to be use…otherwise the wiring won’t work.

At the front plate of switches..all looks the same, you only can identify the differences by looking at the back of those switches (the cable terminal). Figure below illustrate the differences of those switches.

Okay, by now you should knew the concept and switches to be used..this is the final part, how to do the wiring!

Figure below illustrate the wiring diagram for 1 way, 2 way and intermediate switch.

Wish you all the best..tq.
