Staircase 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
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.
