    Big Switch Battery Disconnects

    Top racers realize that using a low amp switch creates resistance and actually reduces power. Flaming River's heavy duty battery disconnect switch is top of the line designed for complex electrical systems and 16 Volt batteries.

    The lever kit allows for remote actuation of the Big Switch. The kit includes an 18" long, aluminum threaded rod, T-handle, mounting bracket and necessary hardware. A "push off" decal is included. Accepted for IHRA/NHRA competition use.


    • Rated at 250 amps continuous service (12/16/24V) and 2500 amps for 5 second surges.
    • Spring-loaded, vibration resistant, waterproof design.
    • Accepted by most sanctioning bodies including IHRA/NHRA.
    • Furnished with an easy-grip T-handle, anodized aluminum bracket and zinc plated mounting hardware.

    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.
