context_page_description: A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power.
  An Automatic Transfer Switch is often installed where a backup generator is located, so that the generator may provide temporary electrical power if the utility source fails.
