Transfer Switches (also known as automatic transfer switches or ATS) are electrical devices used to switch between two power sources, typically from the grid to a backup generator during a power outage. Commonly used in residential, commercial, and industrial settings, they ensure a seamless transition of power, preventing downtime and equipment damage. Transfer switches are essential for maintaining continuous power supply and protecting critical systems.
