Variable Speed Control for older style Motorized Bobbin Winders

This speed control can be used to replace the foot pedal on older style bobbin winders.  It has an “electrical outlet” on the side of the box into which the short cord from your motor plugs in.  In turn, the Variable Speed Control has it’s own short 3 prong cord that plugs into a nearby electrical outlet.  You can choose any speed with the knob.
