This is only for the foot switch pictured and I don’t have any way to test it out. I will accept returns within two days of delivery in the event that it is completely non functioning. Cosmetically it looks good, there is part of the plastic molding missing around the power button as shown in the photo. The chord is in good shape with no tears or breaks, inside is clean and all the solder joints look good. I don’t know much about these but feel free to ask any questions and I’ll do my best to answer.
