One of the harmful factors that came with the introduction of electricity was the casualties resulting from shocks. These casualties ranged from minor to fatal and were a cause for great concern, until the invention of Safety Switches. Although important, not many people are aware of what safety switches are, their utility and need for installation, thus, this article is to assist you in its basic education.
Basic Functioning of Safety Switches
Electricity flows inside a circuit, however, if an individual makes a direct contact with it, then the electricity deserts the original path of flowing inside the circuit and goes on to flow through the individual and towards the earth. Safety switches prevent this shocking by detecting a change in the path of the electrical flow and abruptly stopping the flow of electricity in less than a second, ultimately saving the life of the individual.
Difference Between Safety Switches And Circuit Breakers
Many people might still be confused and ask if there is any difference between safety switches and circuit breakers. To answer their question, yes, there is a major difference. While circuit breakers and fuses protect against short circuits and current overload, safety switches are the sole protection against shocks, thus are important.
Do I Already Have Safety Switches
If you’re wondering if you already have safety switches installed then here is a fun fact: By the 1991 law, all houses or buildings built should be installed with safety switches. So if your house is built after 1991, then it’s likely that you do have safety switches. Nevertheless, it’s still good to contact an electrician and confirm if you have them and then install if not.
It must be noted that while their function is to protect individuals against shocks, safety switches still might not be applicable to all wirings and appliances.
