How to Wire a Light Switch? Controlling a Lamp by Single Way Switch
In today’s basic home electrical wiring installation tutorial, we will show how to wire a light switch to control a light point using one way or single way switch.
We will use the basic SPST (Single Pole Single Throw) switch in this tutorial to control a lamp/bulb from a single location.
Good to Know: Single Pole, Single Throw (SPST) switch is known as Two way switch, toggle switch or Light switch having three terminals (two for lines and one for ground) in North America (US – NEC).
Before going in details, we have to show the basic construction and operating mechanism of single way switch which is shown in fig below:
Below is a simple step by step tutorial with schematic and wiring diagram which shows how to wire a light switch to control the bulb/lamp from single place with the help of one-way or single way switch?

How to Wire Single Pole, Single Throw (SPST) as 2-Way & 1-Way Switch? IEC & NEC
How to Wire Single Pole, Double Throw (SPDT) as 3-Way & 2-Way Switch? IEC & NEC
Requirements:
Single Way Switch (SPST = Single Pole Single Throw) x 1 No
Lamp (Light Bulb) x 1 No
Short pieces of cables x 3 No
Procedure:
This is just like a series circuit i.e. All the components are connected in series. Just connect the Neutral wire directly to the light bulb and then connect the light bulb to the switch through the middle wire. And then connect the live wire to the switch as shown in fig below. Fig given below shows the basic connection of light switch and their position i.e. When the switch is OFF, the circuit acts like an open circuit and the bulb does not glow. To switch on the bulb, switch S1 must be closed to complete the circuit and glow the light bulb.
Also note that home wire colors may vary according to different areas. In addition, always use and connect the earth wire (direct naked wire to switches, and electrical appliances from earth link in the distribution board to reduce the risk of electric shock and hazard) which is not shown in the figures above.
