1. A power-distributing device for a vehicle electrical system of a motor vehicle, comprising:
at least two power source terminals;
at least two safety supply terminals;
a coupling apparatus to electrically couple the at least two power source terminals to the at least two safety supply terminals;
at least two source switching elements, each source switching element of the at least two source switching elements configured to electrically couple a power source terminal of the at least two power source terminals with the coupling apparatus depending on a switching state of the at least two source switching elements;
at least two safety supply switching elements, each safety supply switching element of the at least two safety supply switching elements, configured to electrically couple a safety supply terminal of the at least two safety supply terminals with the coupling apparatus depending on a switching state of the at least two safety supply switching elements; and
a bypass circuit including at least one diode, the bypass circuit connected in parallel with a safety supply switching element of the at least two safety supply switching elements and configured to, with a switching state of the safety supply switching element being a turned-off state, supply power to a safety supply terminal of the at least two safety supply terminals that corresponds to the safety supply switching element through the bypass circuit.
