Abstract
Methods and systems for selecting and connecting an electronics package to a power source from one or more of a plurality of possible power source paths. An embodiment of the invention uses inexpensive analog components to select a power path by testing the possible power source paths for a desired potential. The invention interrupts the alternate power path while maintaining the connection of the electronics package to the power source through the selected power path. An optional removal circuit removes the testing and selection circuitry once the alternate power path is interrupted. In actual embodiment of the invention, the methods and systems described are included in a reversible circuit breaker.
