To install the wrings of any switches, be it a one gang or a two gang switch, we have to understand first how a electrical circuit works. The electrical current we use in our house is called alternating current or AC. This means the current flows continuously alternating from point A to point B in a continuous loop. Once this loop is broken and the flow of current is disrupted at any point of the loop, the circuit stops to work. We can imagine the flow of current like a rubber band. It must be a continuous. Now the purpose [...] Read more »
