| An automatic transfer switch includes first and second magnetically latched relays that respectively connect first and second voltage sources to a critical load. The first and second relays are magnetically latched in their respective opened or closed positions by a permanent magnet so that no holding current is supplied to the relays after switching is completed. As such, no holding current is required for either relay in the non-transferred or the transferred state of the automatic transfer switch, which reduces heat generated by the relays which can lead to relay failure.
