1. A latch system for a door of an automobile, comprising:
- a first power source;
a second power source;
a latch assembly for the door coupled to the first power source and the second power source;
an electronic control unit configured to control an operation of the latch assembly, the electronic control unit further configured to;
determine a status of the first power source,evaluate the status of the first power source, andselect the second power source for operation of the latch assembly if the evaluation of the status indicates the first power source is insufficient to operate the latch assembly; and
a Single-Pole, Double-Throw (SPDT) switch having a common terminal coupled to the latch assembly, a first line terminal coupled to the first power source, and a second line terminal coupled to the second power source,wherein the electronic control unit is configured to place the SPDT switch in a first throw position that couples the first power source to the latch assembly when the evaluation of the status indicates that the first power source is sufficient to operate the latch assembly and in a second throw position when the evaluation of the status indicates that the first power source is insufficient to operate the latch assembly.
