An automatic transfer switch is an electrical device that switches a load between two sources as soon as it senses a loss of power. These units are particularly useful on backup generators as they will start up as soon as the main power source fails. The automatic transfer switch can also start a backup generator if it senses voltage fluctuations. It will automatically disconnect the main power supply when the generator switches on. When the power comes back on the automatic transfer switch will turn the generator back off. Some transfer switches can prioritise certain circuits that are essential and route the power to them only. The switch can be set by the user to comfortable cover all their requirements.

The transfer switch isolates the generator from mains power when the generator is on.  This is to ensure that there is no feedback into the mains line.
