摘要
An electronic circuit arrangement may include first and second electric connections connectable to first and second electronic devices, respectively. A first electric conduction path may connect the first and second electric connections, and a second electric conduction path may connect a tee point provided in the first electric conduction path to an electric ground connection. First and second switching elements may be provided in the first and second electric conduction paths, respectively, between the tee point and the respective electric connection. Each switching element may switch between an open state, in which the switching element may interrupt the respective electric conduction path, and a closed state. In response to connecting the second electronic device to the second electronic connection, the second switching element may switch to the open state, and the first switching element to the closed state only after the second switching element is already in the open state.
