Types of Modern Light Switches

Every house, building, or industrial structure has a light switch. It is one of those things we usually do not give attention to but plays a crucial role in making life convenient. We use the switch to adjust lighting in our living spaces. Some of the things that will never work without flipping a switch are light bulbs, pendant lights, recessed fixtures, and chandeliers.

You don’t give so much thought about the light switch because it gets the job done without any problem. However, did you know that like all other components in your home, you must learn how modern light switches Australia work so that you can figure out there is a problem with them or they need replacement?

So, let us look into the two most common and preferred types of a modern wall light switch.

1 – The Simple On/Off Variety

This kind of switch is often referred to as single location switch because it turns the light on or off from only one area. Aside from that, single-pole, single throw (SPST) switch is the technical or proper name of On/Off switch. Single-pole means that only one “hot wire” can be connected while the single-throw means that when you switch it. It will just link to one other line which is the path going to your light. The technical or another proper term of an On/Off light switch is the single-pole, single throw (SPST) switch. Single-pole means only one “hot wire” can be attached to it. While on the other side, single-throw will only connect to one other wire when you switch it — the wire going to your light. Thus, it is best for single operation mainly to just turn on and turn off the light.

 

 

2 – The Three-Way Switch System

Single pole, double- throw (SPDT) switch is the technical name of a three-way switch wherein the single pole means only one “hot wire” is connected to it. Unlike the first type, it features two connected wires. The three-way switch redirects the connection of the hot wire back and forth between two other cables. Electricians call these two wires as travellers since they connect to a second three-way switch ultimately while the second switch is the one carrying the power going to the light.

For a much simpler explanation, we paint a picture in which the three-way switch looks like the letter V. In this example, each point is the terminal where the hot wire that is from your breaker or fuse panel and the load wire going to the light become connected. As a result, you can turn the light on and off from two different areas since one of the switches is powered by the panel that is connected to the common terminal. The three-way switch is one of those modern light switches Australia uses in many settings today because of its versatility.
