How to Control a Light Bulb using Single Way or One-Way Switch?
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). While it is known as Two Way switch (having two terminals) in the Europe, UK and IEC following countries.
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?
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.
In fig below, schematic and wiring diagrams of light switches are shown which shows how to wire a light switch?
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.
In the following step by step meter installation guides, we will show how to wire a single phase electric meter for 230V AC (UK, EU based on IEC) and installation of single-phase 120V and 240V (US based on NEC) regulations for existing or new mains service installation.
For general and clear illustrations, we have used the RED color for Phase, Line or Live wire while the BLACK color shows the Neutral wire. The color coded versions are also included for both IEC and NEC wiring color codes.
Single Phase Meter Wiring for 230V AC – (UK & EU) – IEC
In UK, EU, Asia and IEC following countries, the single phase supply of 230V AC is provided by two wires systems (Phase & Neutral) from the transformer (Single-Phase 230V, or Three Phase 400/230V Transformer) to the meter box and further to the main distribution board in the residential premises.
An electric meter (aka energy meter or kWh meter “kilo-watt-hour”) can be digital (smart with an LED display known as electronic meter) or analog (electromechanical) having a rotating aluminum disk. Nowadays, smart electric meters are commonly used due to extra useful features and advantages over the old school technology, That’s why the Govt of UK required electric energy suppliers to install smart meters instead of analog meters.
Installation of Single Phase kWh Meter (1-Phase, 2 Wires, 230V AC Energy Meter)
First of all, make sure to disconnect the main power before working on electrical installations.
Starting from the left side for MAIN, connect the incoming (from transformer) Phase (Line) wire to to the 1st slot on the meter (Main).
Connect the incoming Neutral (N) wire to the 2nd slot on the meter.
On the Load side, connect the Outgoing Neutral in the 3rd slot.
Now connect the outgoing Phase wire in the 4th slot and connect it to the main distribution board as shown in the fig.
