Product Name: MOROSO Type Battery Cutoff Switch Kill Switch Disconnect Impala Cadillac Caprice Hydro Lowrider MOON Includes ON/OFF markings, terminals, and cover. This item is essential for racing cars, but it's also recommended for preventing battery drain in hobby cars like classic cars that are not driven frequently. Made of metal, it's rated for 12V and approximately 125A. Terminal mounting screw diameter is about 10mm. This is a high-capacity racing type. Its simple appearance makes it a great choice for those who dislike the common, inexpensive red plastic knob-type switches.
