Standard Bernina - Foot Control

This electronic foot control gives you stitch-by-stick control over your sewing speed, whether you want to sew slow or fast. On the front, it features a heel kick (back-kick) feature, letting you raise or lower the needle, secure and cut threads and raise the presser foot depending on what model it is attached to. That feature is programmable on models B 480 and above.

On the back, the cord winder lets you manage the cord effectively.
Note that when the machine is first taken out of the box from the factory, the cord is wound with the connector tucked into the base of the foot control, to avoid interference from the foam packaging when removing the foot control from the box. That is not how the cord should be secured for everyday use.
