Safety Switches: What Are They And Why Do I Need One?

A safety switch is a vital safety device for your home and one that can be easily overlooked. Bredlec is an electrician near you that has expert knowledge about these safety devices and know the most secure option for your home or office. Bredlec Electrical offers the installation, repairs and testing of safety switches in Wollongong and the greater Illawarra. Below, we've covered all you need to know about safety switches and why you need one installed and maintained in your residence.

What is a Safety Switch?

A safety switch is a mechanical device that helps to prevent accidents by automatically shutting off power to a circuit when it detects a problem. This can be useful in a variety of situations, such as if there is a short circuit, or if something comes into contact with an energised wire. They are normally found in homes and businesses, and are compulsory in NSW. They are usually located near electrical panels, and can be easily reset if tripped. Safety switches work by sensing when something is wrong and then shutting off the power before an accident can happen.

How does a Safety Switch work?

To answer this question, we must first understand what electricity is and how it works.

Electricity is the flow of electrons through a conductor, such as a metal wire. The speed at which the electrons flow is what we call “voltage”. The more voltage, the faster the electrons flow. The amount of current (measured in amperes or “amps”) is determined by the number of electrons flowing through the conductor per second.

The safety switch is designed to protect people and animals from electric shock. It does this by breaking the circuit when it detects a current that is higher than normal. This prevents the current from flowing through the body of a person or animal who may come into contact with the live wire.

Why do I need one?

Safety switches are an important part of keeping you and your family safe. They activate in 0.03 of a second, preventing electrical injury, shock and death. They are usually fitted to power points and light fittings in homes and offices, and to all circuit breakers in your fuse box and can help prevent electrical shocks, fires, and other accidents. If you have young children or pets, a safety switch can be especially important.

Safety switches are also required by law and are often installed in homes and businesses as a safety measure. They are typically located near electrical outlets, and can be easily reset if needed.

Importance of a Safety Switch

A safety switch is an electrical device that is used to protect people from electric shock. It is designed to break the circuit if there is a problem with the wiring or if there is a sudden surge of electricity. This can prevent serious injuries or even death.

Safety switches are also required by law and it is compulsory that every home has one. They are relatively inexpensive and can be installed by a qualified electrician at Bredlec Electrical. It is important that you keep up with the maintenance of your safety switch to keep up with NSW standards and the safety of your home.

If you are ever unsure about whether or not your home has a safety switch, don't hesitate to contact our team at Bredlec. One of our expert electricians can come out and inspect your electrical system to ensure that everything is up to code and that you and your family are safe.

Types of Safety Switches

There are two main types of safety switches: circuit breakers and ground fault circuit interrupters (GFCIs).

Circuit breakers are devices that interrupt the flow of electricity in a circuit when they sense an overload. This prevents circuits from overheating and starting fires. At Bredlec Electrical, we like to use the top of the range and safest circuit breaker, which is the RCD (residual current device).

RCDs are a life-saving device which prevents you from getting fatal electric shocks. They are a sensitive safety device designed to detect the slightest stray current, even if the wire is not in contact with you, and will cut off the power flow. RCDs offer a level of personal protection that ordinary fuses and circuit-breakers cannot provide.

An RCD is designed to protect against electrocution and fire caused by earth faults. For example, if your lawnmower accidentally cuts a cable and touches the exposed live wires or a faulty appliance in the home overheats causing electric current to flow to earth, then an RCD will kick in and switch off the electric supply in time.

GFCIs are devices that sense when current is flowing through a circuit in an unintended path, such as through water or a person. When this happens, the GFCI interrupts the flow of electricity to prevent shock.

Safety switches are important because they protect people and property from fires and shocks. They should be installed in any circuit that could be hazardous, such as those in kitchens, bathrooms, and outside.


A safety switch is a device that is used to help protect people from electrical hazards. They are required by law and they are a great device to have to help you rest easier that your home, family and pets are less at risk. Safety switches can help to prevent electrocution and other serious injuries, so it is worth taking the time to learn about them and to make sure that you have one installed and maintained in your home.

Did you know that most home fires originate from a faulty appliance? Did you know that smoke and CO alarms are the best way to protect your family from these dangers? This article will give you all the information you need to choose the right type of alarm for your home, as well as show you why they're so important.

What are Smoke Alarms?

Smoke alarms are an important part of any home. They provide early warning of a fire, allowing you and your family time to escape. Smoke alarms can be either battery operated or hardwired into your home’s electrical system.


Smoke alarms come in many different shapes and sizes. They can be wall-mounted or free-standing, with a variety of features available. The type of smoke alarm you need depends on where it will be located, the fire hazards in your home, and other factors like whether your home has smoke alarms already installed.

Why You Need Smoke Alarms

Smoke alarms save lives and are an important part of any home security system. They give you and your family time to evacuate the premises quickly and safely before the fire becomes too large or spreads too quickly. Having a smoke alarm installed in your home or business can help prevent the damage and loss of life that occurs when fire breaks out. They can also help to prevent property damage by alerting you to a fire before it has a chance to spread.

Smoke alarms are also compulsory by law in Australia and must be installed in every residential building, on or near the ceiling of every storey. An expert at Bredlec Electrical can install and maintain your smoke alarms to ensure you are keeping up with Australian standards.

How to Choose a Smoke Alarm

When it comes to choosing a smoke alarm for your home, there are a few things you need to take into account. The most important factors to consider are the type of smoke detector, the placement of the smoke alarm, and the power source.

There are two main types of smoke detectors: ionisation and photoelectric. Ionisation smoke detectors are more sensitive to smaller, invisible particles that are produced by flaming fires. Photoelectric smoke detectors are more sensitive to larger particles that are produced by smouldering fires.

The placement of your smoke alarm is also important. You should have at least one smoke alarm on each level of your home, and they should be placed outside of each sleeping area. Smoke rises, so it is important to place your detectors high on a wall or on the ceiling.

Finally, you need to choose a power source for your smoke alarms. The best option is to choose an alarm that has a battery backup in case of a power outage.

Different Types of Smoke Alarms

When it comes to choosing a smoke alarm for your home, you have several different options to choose from. Here are some of the most popular types of smoke alarms on the market today:

1. Ionisation Smoke Alarms: These alarms work by detecting particles of combustion in the air and then sounding an alarm. They have a small amount of radioactive material that creates an electric current. This current flows between two metal plates, which creates a small magnetic field. If smoke enters the chamber, it disrupts the flow of current and sets off the alarm.They are typically the most affordable option and are often used in homes.

2. Photoelectric Smoke Alarms: These alarms work by detecting smoke in the air and then sounding an alarm. They have a light source that projects a beam of light across the chamber. If smoke enters the chamber, it scatters the light, which triggers the alarm. They are more expensive than ionisation alarms, but they are less likely to cause false alarms.

3. Dual-Sensor Smoke Alarms: These alarms have both ionisation and photoelectric sensors and are considered the best option for home safety. They are more expensive than other types of smoke alarms, but they provide the highest level of protection.

Some smoke alarms also have carbon monoxide detectors built in. Carbon monoxide is a colourless, odourless gas that can be deadly. A carbon monoxide detector will sound an alarm if it detects high levels of carbon monoxide in your home.

There are many different types of smoke alarms available on the market, so it is important to choose one that best suits your needs. Some smoke alarms are designed to be used in specific areas of the home, such as the kitchen or laundry room. Others are designed to be used in all areas of the home. They should be placed on every level of your home, including the basement, and outside of each bedroom and near any sleeping areas. Smoke alarms should also be placed near any potential fire hazards in your home, such as the kitchen where the stove and electrical appliances live.

Smoke alarms come in both battery-operated and hardwired varieties. Battery-operated smoke alarms are easier to install, but they may need to be replaced more often than hardwired units. Hardwired units are more expensive, but they will last longer and are less likely to need replacing.

When choosing a smoke alarm, it is important to consider the size of your home and the type of fire that is most likely to occur. Smaller homes may only need one or two smoke alarms, while larger homes may need several units. If you live in an area where wildfires are common, you may want to invest in outdoor fire alarms.
