Hello Larry, the metal part that controls the switch is missing. But when it is working when you connect it to the brake switch, then it is fine by me. ThanksNo one makes that new. Your only hope would be to find one used I would think. What exactly is wrong with it? You might be able to find a micro switch that you can make work. You can also mimic the function by splicing into the switched wire of the brake switch. That would give you high stall when your foot is on the brake.
