Importance of the Safety Switch
A safety switch is designed to prevent an electric shock and save lives.
They monitor the flow of electricity through a circuit and automatically shut off the electricity supply when current is detected leaking from faulty switches, wiring or electrical appliances. This stops the chance of current flowing to earth, through a person, electrocuting them. These switches typically switch off the power within the time span of 10 to 30 milliseconds once dangerous levels of electricity are detected. Safety switches can therefore be considered as devices which prevent grievous injuries and even possible death caused by electric shocks. Safety switches are also called residual current devices (RCD).

Installation and types of safety switches
Safety switches can be classified into three types:
- Switchboard units – these are located on the main switchboard and offer complete protection during installation and maintenance
- Power point units – these switches are installed in standard power points for single point or single circuit protection
- Portable units – offer a high degree of convenience and can be used with extension cords and portable power tools
Installing a safety switch is a necessary safety measure. It protects everyone and is a mandatory requirement in all new homes. It is advisable to install all the safety switches which you require around the house at the same time which will help you to save on installation costs. Safety switches are not the same as circuit breakers or fuses. They are an additional form of protection to be used with circuit breakers and fuses.
Don’t Forget: Electrical work is never a do-it-yourself job! That’s dangerous and illegal.
Shown below are some of the essential devices that you should have in your home to safeguard against electrical damage:
Surge protectors safeguard your appliances and wiring from voltage surges such as those resulting from a lightning strike. Safety switches and surge protectors play entirely different roles – surge protectors protect electrical appliances, safety switches protect people.
Before purchasing a surge protector, consider the number of ports that you are going to need depending on the number of your devices. Most surge protectors come with 6 or 8 ports though there are protectors which offer additional ports should you require such a one. Also keep in mind the kind of devices that you’re going to plug into the surge protector. Suppose you are purchasing the surge protector for your TV and home theatre, it would be a good idea to purchase a higher quality one. Compared to say, if you’re planning to just connect a simple lamp or charger. Some surge protectors also offer warranty on the devices connected to it (up to a certain amount), in the event of an electrical surge or spike. So check to see what’s covered by the warranty and what isn’t before purchasing.
Surge protectors are particularly useful for households which are located in areas which face frequent thunderstorms as your devices are then even more likely to experience power surges.
Circuit breakers cut the power off when electrical wiring in a building has too much current flowing through it. Too much current flowing through a circuit would heat an electrical appliance’s wires or the building wiring to unsafe levels. This could result in an electrical fire. Circuit breakers are normally rated either by the amount of normal current that they can carry or the highest level of short-circuit current that the circuit breaker can interrupt safely.
Fuses work in the same way as circuit breakers providing protection in the case of overcurrent. In terms of cost, fuses are cheaper when compared to circuit breakers but are less convenient. The difference between the two is that while a fuse must be replaced with a new device after it is used, a circuit breaker can be reset and used again. It is important to note that both fuses and circuit breakers do not provide personal protection against electrical shock.
Safety switches monitor the flow of electricity through a circuit. They automatically shut off the electricity supply when current is detected leaking from faulty switches, wiring or electrical appliances. This stops the chance of currents flowing to earth, through a person, electrocuting them.
Portable safety switch
A portable safety switch unit is ideal when using plug-in electrical equipment used indoors or outdoors. They are convenient to use where permanent safety switch protection is not available. However the portability of these devices means they can be subject to damage and should be inspected regularly.
