When to hire an electrician
In Australia, it is illegal to perform electrical work without a license. Electrical work must be completed by a licensed electrician or a registered electrical contractor (REC).
Even small electrical jobs can be dangerous, so it is always best to hire a qualified electrician. Electricians undergo training, seminars, and assessments to ensure they are equipped to handle electrical systems safely.
- Electrical faults and damages: If you experience frequent bulb burnouts, switchboard tripping, or other electrical faults, an electrician can inspect your components and advise on necessary repairs or upgrades.
- Light switch issues: Light switches wear out over time, especially in older properties. If your light switch is not functioning properly, making weird noises, or showing signs of damage, an electrician can safely replace it.
- Burning odours and unusual sounds: If you notice burning smells or hear audible frying sounds, it could indicate an issue with your wiring. Electricians can trace back the wiring and address any problems.
- Emergency situations: In the event of an electrical emergency, such as a power outage or a faulty light switch, you may need to call an emergency electrician. They are available 24/7 but may charge a higher rate.
- Installation and repairs: For any installation or repair work involving electrical systems, it is crucial to hire an electrician. This includes installing new light fixtures, checking wiring, or repairing electrical appliances.
When hiring an electrician, it is important to verify their qualifications, get multiple quotes, and seek recommendations from past customers. The hourly rate for electricians in Australia typically ranges from $60 to $150, depending on location and job complexity.

How to safely remove an old switch
In Australia, it is illegal to perform DIY electrical work. Only licensed electricians should carry out electrical work in your home. However, if you still want to replace an old switch, here is a step-by-step guide on how to do it safely:
Step 1: Turn off the power
Before touching any electrical component, ensure that you turn off the power at the circuit breaker or fuse box. You can also flip the light switch to ensure that no current is flowing to the component.
Step 2: Remove the switch cover
Use a flathead screwdriver to carefully pry off the switch cover.
Step 3: Unscrew the existing switch
Use a Phillips-head screwdriver to unscrew the old switch from the fittings.
Step 4: Loosen the wires
Pay close attention to the wire colours and their connections as you will need to replicate these connections on the new switch. Loosen the screws holding the wires in place and carefully detach the wires from the old switch.
Step 5: Check the wires
Before installing the new switch, check the integrity of the wires. If some cables seem weak or brittle, trim and re-strip the ends as needed.
It is important to note that attempting to change a light switch without proper knowledge and experience can be dangerous. Electricity is a powerful and lethal energy source, and mishandling it can lead to electrical accidents, fires, and even fatal electric shocks. Always prioritize your safety and consider seeking professional help from a licensed electrician.

The dangers of faulty switches
Faulty light switches can pose several dangers and risks, and it is important to be able to identify them to ensure your safety.
Firstly, a faulty light switch can lead to electrical fires. This can be caused by wiring problems within the switch's electrical box, which can result in short circuits and overloaded circuits. A burning smell, smoke, or scorch marks on the switch are serious signs of a faulty switch and should be addressed immediately.
Secondly, faulty switches can cause electrocution. Loose light switches, in particular, can be dangerous when handled and should be left to professionals to fix.
Additionally, a faulty switch can cause a circuit breaker to trip and shut down power to the circuit. This can be due to an overloaded or short circuit, which can be caused by a faulty switch. A tripped circuit breaker can also be a sign of a malfunctioning switch, so it is important to identify the root cause.
Other warning signs of a faulty switch include abnormal behaviour, such as a loose toggle lever, delayed lighting response, or unusual noises like snapping, popping, or buzzing. If you notice any of these issues, it is recommended to call a licensed electrician to replace the switch promptly.
It is worth noting that changing a light switch is considered unlicensed electrical work in Sydney, and only authorised electricians should perform these tasks to ensure safety and avoid potential fines.
