This is a new replacement power cord for many older Singer sewing machines, including the 609, 620,625, 626, 628, 629, 635, 636, 638, 639, 645, 646, 648, 649. This is part # 618817-001.
This is NOT the correct cord for the Singer 600 or 603 -- that takes the same cord as the Singer 500, which I also have available for sale.
I test each cord before I ship it to ensure that it fits and works well. If you have any questions about which cord is the correct one for your machine, please contact me before ordering.
I also sell new, generic foot controls. If you purchase both the foot control and the cord at the same time, I would be happy to wire the cord into the control and test it before shipping to you -- at no additional charge.
