First off, I am not technical, just a 73 year old sewing pensioner.
My original foot pedal would stop in the middle of sewing, light off, until I lifted my foot, light came back on, and I began sewing again. I really had to find a sweet spot for my foot as well.
So I received the pedal today. Sadly it sews slower than the power button on low. The power button is sitting on high. I lift my foot off the pedal and the machine continues to move at a snail pace without me doing a thing. I have to remove the 1 pin plug to stop it.
In other words it doesn’t work. It looks the same as my current foot pedal, same 1 pin plug, it just doesn’t work as a sewing machine foot pedal should.
Remember, I’m not technical, no car to go driving to get somebody to look at it either.
