2-Way & 3-Way Switching Connections – Electrical Wiring Diagrams

What is Two Way & Three-Way Switching Circuits?

Two-way switching or (three-way circuits in the US) connection is used to control electrical appliances and equipment like fan, lighting points etc. from different places using 2-way & 3-way switches. The most common use of 2-way switching connection is staircase wiring where a light point can be controlled from two, three or even many locations. No matter what is the position of flowing electric current in the two way switch (ON or OFF), the connected appliance like bulb can be switched ON / OFF by pressing the button.

Please don’t kill me to mention it 2-Way switch instead of 3-Way switch as whatever we have used is the same thing for specific applications.
