An Automatic Transfer Switch (ATS) having a switch configured to connect one of two sources to a load, a mechanical drive, an actuator, and a solid state control relay is disclosed. The mechanical drive is configured to drive the switch between a first position and a second position, the first position connecting the switch to the first source, and the second position connecting the switch to the second source. The actuator is in mechanical communication with the mechanical drive to cause the mechanical drive to move on command. The solid state control relay is responsive to an external signal and productive of a control signal, wherein the actuator is responsive to the control signal to cause the mechanical drive to move.
