Environment activated automatic shut-off switch system and method

摘要

An environment-activated automatic shut-off switch is disclosed. The disclosed embodiments allow power to be removed from a trailer auxiliary power circuit when the environment-activated automatic shut-off switch senses that the trailer is being put into motion. The disclosed embodiments of the environment-activated automatic shut-off switch do not require external control signals, such as those received from a vehicle tractor, in order to effectively control the trailer auxiliary power circuit and to ensure that the trailer ABS circuit has dedicated power while the trailer is in motion.
