How to Control a Lamp / Light Bulb from Two places Using Two Way switches For Staircase Lighting Circuit

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.
