| 摘要 |
The invention relates to a circuit arrangement for operating electric or electronic components in a motor vehicle with a two-voltage onboard network, with a direct current/direct current converter which comprises at least one input terminal, at least one output terminal and one ground terminal, with the input terminal being adapted to receive an input switching signal between a first voltage level and a ground level, and the output terminal being adapted to emit an output switching signal between a second voltage level, different from the first voltage level, and the ground level, the signal characteristic of which essentially follows the characteristic of the input switching signal, with the voltage converter with its input, output, and ground terminals being arranged in a housing which comprises a socket and which corresponds to a relay with respect to the dimensions and the positions of the input, output, and ground terminals at the socket.
