Question

connection and control one lamp with one switch​

Answer 1

In this tutorial, we will show you how to make 2-way switching connection. A 2-way switching connection means you can control an electrical equipment like bulb by two switches placed at different places, generally used in the staircase. Two way switch can be operated from any of the switch independently, means whatever be the position of other switch(ON/OFF), you can control the light with other switch.
