The invention relates to an on-board motor vehicle electrical system (1) comprising a first voltage supply system (2a) and comprising a second voltage supply system (2b). The first voltage supply system (2a) has a first voltage source with a relatively low voltage, and the second voltage supply system (2b) has a second voltage source with a relatively high voltage. Furthermore, the first voltage supply system (2a) and the second voltage supply system (2b) are DC-isolated from one another and connected to one another in a signal-transmitting manner by a coupling element (3). The second voltage supply system (2a) has at least one electrical switching element (4) for a load (5), and the on-board motor vehicle electrical system (1) has a control apparatus (6) for controlling the load (5) by means of the respective switching element (4). According to the invention, the coupling element (3) is connected to the respective switching element (4) in a signal-transmitting manner by means of the control apparatus (6).
