Automatic transfer switch for switching an electrical load between two power sources. In one example, the automatic transfer switch includes four latching relays and an electronic controller. A first power source line connection is connected to an electrical load line connection via a first latching relay. A first power source neutral connection is connected to an electrical load neutral connection via a second latching relay. A second power source line connection is connected to the electrical load line connection via a third latching relay. A second power source neutral connection is connected to the electrical load neutral connection via a fourth latching relay. The electronic controller connects the second power source to the electrical load when a voltage of the first power source is less than a first threshold, and connects the first power source to the electrical load when the voltage is greater than a second threshold.
