Controlling of Each Lamp by Independent Single way Switch in Parallel Lighting Circuit?

In today basic home electrical wiring installation tutorial, we will show how to wire and control each lamp independently by using separate single way switches in parallel lighting connection.

Below is a simple step by step tutorial with schematic and wiring diagram which shows how to wire three different light bulbs in parallel to control from three different and independent switches and locations?

Requirements:

Single Way Switches (SPST = Single Pole Single Through) x 3 No
Lamp (Light Bulb) x 3 No
Short pieces of cables x 11 No

Procedure:

Connect all the wiring connection as shown in fig below.

How to control each lamp separately by single way switches in parallel lighting circuits

The first and second Lamps are glowing, because both the separate switches S₁ and S₂which are connect to the bulbs through Line are at ON position and so the circuit is completed.
The third Lamp is OFF, because switch S₁ which is connected to light bulb through Line is OFF, so the circuit behaves like an open circuit meaning there is no way to flow the current in the circuit. Hence, bulb is not glowing

Now consider the following schematic wiring diagram. It is the same circuit as shown above but the switches and light bulb postpones just reversed i.e. S₁ and S₂are at OFF positions, so Lamp 1 and Lamp 2 are OFF while S₃ is ON and Lamp 3 is glowing.

Good to know:

Switches and fuses must be connected through line (Live) wire.
Connecting electrical devices and appliances like fan, outlet, light bulbs etc. in parallel is a prefer way instead of series wiring.
Parallel or series-parallel wiring method is more reliable instead of series wiring.

Warning:

Electricity is Our Enemy, if you give it a chance to kill you, Remember, they will never miss it. Please read all caution and instruction while doing this tutorial in practical.
Disconnect the power source before servicing, repairing or installing electrical equipment.
Never try to work on electricity without proper guidance and care.
Work with electricity only in presence of those persons who has good knowledge and practical work and experience who know how to deal with electricity.
Read all instruction and cautions and follow them strictly.
Doing your own electrical work is dangerous as well as illegal in some areas. Contact the licensed electrician or the power supply company before practicing any change in electrical wiring connection.
