Stair case wiring circuit diagram, OR How to control a lamp from two different places by two ,2-way switches?
Staircase wiring circuit diagram very simple
 This is the staircase wiring circuit diagram. Here we can control a bulb from two different places by using two, 2-way switches.
                     Now consider this circuit diagram. In this case you can see that circuit is complete and bulb is ON. Suppose you want to OFF bulb from the upper switch at top of stair, simply Switch OFF the switch then circuit will break and the bulb will be OFF. You can switch ON the bulb again to switch ON this Switch. In other words you can OFF and ON bulb from upper switch at the top of stair. Obviously; you can do same from the upper and bottom switch, so let’s see how we can do that from that switch at the bottom of stair.  
                    Now return to circuit again in the pic, In this case you can see that circuit is complete and bulb is ON. Suppose you want to OFF the bulb from the lower switch at bottom of stair. Simply OFF the switch, then again circuit will break and the bulb will be OFF. You can switch ON the bulb again to switch ON this Switch 
Conclusion: 
                   This is a stair case circuit diagram by which we can control a bulb from two different places.We can switch OFF and Switch ON the bulb from both switches at the same time. in other words we can control (OFF or ON) the bulb from upper and lower switches.

This will be more useful and will have a very simple explanation

This image also explain the basic concept of this circuit

    THE DIAGRAM SHOWS A CONDUIT ENCLOSED PVC SINGLES STYLE WIRING IN AN ENVIRONMENT THAT WOULD BE TYPICALLY WIRED WITH TWIN AND EARTH CABLE, WHICH IS SLIGHTLY DIFFERENT. I WOULD ARGUE THAT THIS DIAGRAM WOULD CONFUSE A D.I.YER.

    1. No Dear...Don't Confuse with that kind of wring diagrams...
      Its is not a layout...it is just a typical wiring diagram... So you can connect with earth cable..it is just showing only stair-case wiring diagram. not the whole wiring.

  5. that method is outdated and we now use 3core and earth run between the two 2way switches,which means there is a single run of twin and earth from the ceiling rose(that is your feed and switch wire and an earth conductor to the first 2way switch,feed to l1,switch on l2,the 2way switches are then joined by 3core and earth...doing it the way shown can be to be done in conduit

    1. that's is not matter what kind of wire to be use 3 core or single wire the important is you know how to connect 2 way switch to ceiling rose or splicing it using electrical tape.

  7. hey admin.... its me ...john.. in philippines... we called it 3 way switch(controlling 1 lamp by 2 switches... not 2 way.... and 4way(controlling 1 lamp by 3 switches

    sir i want to control stair bulb from 1st floor and from ground floor. 3 pin switches(at 1st floor and at ground floor) are already attached to board but i don't know how to connect wires.

    note:- there are 3 pins in the backside of the switch

  9. I want to know if this idea can be implemented using logic diagram or rather built in the lab using bread board, logic gates or IC's. If there is any idea, please post the dia and description

    Depending upon the prerequisites, men and women can place numerous buttons in addition to screwless light switch sockets on top of a utility circuit. You should do a few likely to ascertain wherever you should have these individuals previous to purchasing that.
