Modelling of flexible power cable

Hi

I am creating a lamp for my portfolio and would like to model the power cable for it to be rendered. However I am having trouble creating this using the sweep extrude tool, and getting frustrated 3d sketching as height keeps changing as i adjust the curvature of the lines and therefore unable to complete the task. If anyone could help me out I would be very grateful. I have included the files of what i have managed so far, but if you can imagine the cable between the switch and the socket needs to look longer (possibly two loose loops).

Thanks
