As electrical website owner it's my responsibility to write about electrical technology. In this post i am writing about two way light switch diagram Or staircase lighting wiring diagram. Today i design a diagram about staircase wiring diagram or it's lighting diagram. In this type of wiring we control a lamp or light bulb from two places using two way switches. I already published a explanation guide about two way switch and it;s uses, you can find it by using below link.
How to wire 2 way switch?

Why Two way light switch wiring is important in Staircase circuit

Staircase circuit connection wiring is different from one way control light switch and we did not use one way switches in this connection because we need to controlled or switch off/on the lamp from both places top and down. For that we control lamp from two places using two way switches. In short this connection we use to save energy and to control or switching lamp / light bulb from both places.

How Two way control light bulb connection is works

In this wiring connection we use two way switches in which we have three terminals, in these terminals one is common and two for connection. we can use it for many connection using different connection methods. For example we use it changing flow of current positive to negative etc. However for better understanding  about two way switches open below link.

How To Control a Lamp / Light bulb from two places using 2 way switches

The circuit of controlling lamp from two way switch is simple, in this connection we use two way switches, for this first of all connect the neutral wire to the lamp or bulb socket and then connect the phase or Line wire to the common terminal of the first two way switch, the do connection between the other terminals of first and 2nd switch terminals with one another as shown in below diagram. In last connect a wire between lamp socket 2nd terminal and 2nd switch common terminal as shown below image plus diagram.

I hope you learn some thing from this two way light switch diagram, and i hope know you understood this circuit diagram. Now if you have any question or suggestion regarding this then type you message in below comment section.
How ever soon i write a article about this type of wire but with 3 different methods and diagram.

  1. really helpfull ... thank u sir
    like from Pakistan

  2. hi dear sir, greetings!!!!
    it is my pleasure I can write you here. I am always interested in this fields.
    kindly let me know how can I start to learn about electrical wiring.

    1. To learn electrical wiring, you must start form the basic. First of all buy the basic electrical wiring book and read it. then learn electrical wiring online with diagram and other tutorials. Then spend some time with a electrician or electrical wiring installation works.

    2. Pls the name of the basic books

  3. sir,
    it's really helpful.but it's physically not understanding.can u please explain it in details...
    Is there any channel you have provided for the electrical videos that are useful......

  4. sir how to control a motor with star delta automatic starter.

  5. It was wondering if I could use this write-up on my other website, I will link it back to your website though.Great Thanks. A19 Bulb Vs E26 Bulb: What’s the Difference? (And Reviews)
