Video: Understanding Flaming River’s Big Switch 500 Amp Battery Switch


For those of you running modified electrical systems that support an array of aftermarket components like electronic fuel injection, big alternators, high-draw starters, and other electricity-drawing systems; you’ll want to look into the best insurance policy money can buy: a battery quick disconnect.

Last year, Mopar Connection installed a Flaming River Big Switch on our ’72 Dodge Dart Swinger autocrossing “Orange Crush” project car. The super clean installation definitely gave us a sense of security that running live simply couldn’t do. We also knew it served as a stellar security device when activated.

So how does Flaming River’s Big Switch (and other not-so-heavy duty battery cut-offs) work? Flaming River explains, “The Big Switch 500 is a heavy-duty switch which boasts a 500 Amp continuous rating due to its unique internal silver tin oxide pads and silver-plated terminals. The rugged body is made from glass-filled nylon for impact resistance and extreme temperature resistance. The Big Switch 500 can withstand extreme vibration; making it ideal for both the racing and heavy-duty trucking markets.”

The Big Switch equipped with the optional “lock out bracket” is particularly useful as it can be padlocked closed, preventing thieves from being able to quickly arm your vehicle’s electrical system – an option that well worth the investment. Check out this video below to understand how the Big Switch works and how you could benefit from it!
