Multitudes of jobs require the use of electricity for their execution. Within this scope, it is evident the importance that safe procedures are adopted in order to maintain integrity and health, both for users who maintain contact, and for workers who handle electricity. However, even with the adoption of several protocols provided for in manuals or standards, eventual failures in the electrical circuits resulting from overloads, short circuits or leakage of current to earth, can cause serious material and / or physical damage. The concern of this work is focused on the lethality that electric shocks can cause to human beings. In the meantime, the differential switches are exploited as they are an ally in the prevention of electric shocks, a condition in which electrical current passes through the human body. Mostly, the device protects the user in the event of a defect, interrupting the power supply, providing safe operation. The investigation seeks the development of a prototype that meets the requirements of simplicity and cost, without compromising safety, as it is a non-negotiable factor in any activity.
