Abstract
An alternator circuit for alternately operating one of first and second electrical load devices which uses a magnetic latch relay to perform the alternation. The circuit includes a first circuit means for supplying electrical energy from a source to one of said first and second electrical load devices, and magnetic latch relay alternating means having first and second states. The alternating means in a first state interconnects the first electrical load device to the first circuit means, and in the second state interconnects the second electrical load device to the first circuit means. One application of the inventive circuit is for use in controlling the level of liquid in a container within a predetermined range using 2 pumps.
