In this project a prototype of electrical switching control is implemented with different electrical power sources, which provide security that an electrical load is energized, while any of the electrical feeds are present. The backup and main power supply can be from the electrical grid, from a fuel generator and/or from renewable energies depending on the availability of one of these types of electrical supplies. To implement the prototype, the arduino electronic platform was used, which is a board to carry out control projects. In addition, the labview software was used, which shows in a control panel the current situation of the project, which makes the graphics of the outputs and inputs more visible.
