QuickCar's newest and most advanced master disconnect switch has a lightweight black anodized aluminum casing, black mounting plate, and removable red epoxy-coated handle. The 3 stud design allows a battery, electrical system, and alternator to all be connected or disconnected so no back feeding of the electrical system occurs. All studs on this switch are designed for heavy duty 3/8" ring terminals, and no additional jumper wires are necessary.
