Electronic safety shutdown system for motor vehicles

摘要

Electronic switch in motor vehicles comprising a switch network having an input, a first output and a second output and a first switch element arranged between the first output and the second output, a second switch element arranged between the input and the first output, and a third switch element arranged between the input and the second output. Starting switch-on current limitation is enabled if the input can be electrically connected to a battery pole, the first output can be connected to a generator-battery line, and the second output can be connected to a starter-battery line.
