    FR1003-2 is rated 3.5 out of 5 by 2.
    Rated 5 out of 5 by from very nice switch Have it mounted but not hooked up yet. But it looks like very good quality and bought this because it is highly recommended on a lot of racing sites

    Rated 2 out of 5 by from Okay but not great The same switch went bad on my race car and would shut off going down the track. Needless to say that doesn't make me very happy. I only replaced it with another one like it because it is so hard to make things fit on this show/race car and I really didn't feel like fighting it to make a change. HOWEVER, the arm that attaches to the switch to turn it on and off came with a small allen set screw that didn't go far enough in to the shaft. It fell out before I made 10 passes. My transmission shop found it and replaced it with a screw that would actually tighten in the hole and extended all the way through the hole so that the arm would stay on. I am not enamored with the design and execution of this product. It IS pretty and looks good during a car show but it's not very dependable for drag racing and that's what I do more of with this car.
