A light switch work methodically and has a mechanism behind its operation. A light switch turns a light on and off and controls the flow of electricity in a room. In Singapore, most homes have switches that do not use a neutral wire. These switches connect to a live and a load wire.
Homeowners should know about the working mechanism of a light switch to choose the right one for their needs. Therefore, this detailed guide comprehensively covers all aspects of a light switch’s working.
The Basic Parts of a Light Switch
A light switch has a few important parts. The main part is the switch mechanism. This part controls the flow of electricity. When the switch is pressed, it allows or stops electricity from reaching the light.
The switch also has wires that connect it to the electrical system in the home. Most switches in Singapore use a live and a load wire. Another part is the cover plate, which keeps the switch safe and gives it a neat look.
How Does a Light Switch Work in Singapore?
The light switch works in a simple manner. It either allows electricity to pass or stops it. When the switch is turned on, the circuit closes and power flows to the light. The circuit opens, and power stops when the switch is turned off.
In Singapore, most homes do not have a neutral wire in their light switches. These switches use a live and a load wire to control the light. The live wire carries electricity from the power source, while the load wire sends electricity to the light when the switch is turned on.
Types of Light Switches in Singapore
Depending on the light switch working, several varieties are available in the market. A toggle switch is the most common type. It has a small lever that moves up and down to turn the light on or off.
A rocker switch is similar but has a large, flat button that is easier to press. Some homes use a touch switch, which turns the light on or off when tapped. A smart switch is another option. It connects to Wi-Fi and can be controlled using a phone or a voice assistant.
Common Problems with Light Switches
The working of light switches largely depends on the electricity supply from the supply line. Sometimes, a light switch stops working, and loose wiring can be the cause of this problem. If a wire is loose, the switch will not work properly.
Another problem is a worn-out switch. Over time, the switch will break and need to be replaced. A faulty connection can also cause issues. If the wires are not connected well, the switch will certainly not function as expected.
Replacing a Light Switch
If a switch stops working and no remedy is effective to bring it back to its functionality, you need to replace it immediately. First, the circuit breaker’s power must be turned off to prevent accidents. Afterward, carefully remove the cover plate using a screwdriver. Once you complete this step, check the wiring thoroughly to ensure the connections are secure. If the switch is damaged, replace it with another suitable version.
It is important to keep a record of the wires and connect them in the same way as they were connected to the previous switch. Once the new switch is in place, fix the cover plate to complete the process. Finally, turn the electric supply on to test if the switch works properly. If it is, you have successfully replaced a light switch.
