Abstract
A solid state primary power switching network for modular equipment centers (MECs) distributing primary power throughout a vehicle. The solid state primary power switching network includes multiple primary power switch network devices (PPSNDs) of a MEC for controlling and distributing primary power to other MECs spatially distribute throughout a vehicle. In one or more configurations, the PPSNDs have a universal structure in that each includes a common power input source and a plurality of common power outputs. In one or more configurations, primary power sources to the vehicle are switched without a perceivably visible break in power.
