Description: An A/B switch is a device that allows the selection between two electrical circuits or signals. This type of switch is fundamental in applications where it is necessary to alternate between two power sources, data signals, or circuit configurations. In a general technological context, an A/B switch can be used to switch between two inputs or outputs, facilitating the creation of more dynamic and versatile projects. Its design can vary from simple mechanical switches to more complex solutions involving electronic components such as relays or transistors. The ability to select between two options allows developers to implement functionalities such as mode selection, device switching, or management of different power sources. This type of switch is especially useful in systems where flexibility and adaptability are essential, allowing users to customize their experience and optimize performance across various projects.
