American Autowire Battery Disconnect Solutions
When precision electrical control meets American craftsmanship, you get American Autowire's battery disconnect switch lineup—engineered specifically for restoration, modified restoration, and custom automotive projects. Since 1987, this New Jersey-based manufacturer has built a reputation for producing comprehensive electrical solutions that go far beyond basic commodity parts, and their battery switch offerings exemplify this commitment to quality.
Engineered for High-Performance Applications
American Autowire battery disconnect switches are made of high-quality materials with voltage compatibility of 6 to 36 V and manual activation switches. This wide voltage range makes them suitable for both vintage 6-volt systems and modern 12-volt applications, as well as commercial 24-volt setups. Their master disconnect switches feature ratings at 180 amp continuous with 1000 amp surge capacity, providing the robust power handling needed for high-performance builds with aftermarket starters, amplifiers, and electrical accessories.
Remote Master Disconnect Technology
For builders seeking convenience without compromising safety, American Autowire offers sophisticated solutions beyond basic battery switches. Their Remote Master Disconnect Switch Kit includes an SPST latching solenoid rated at a continuous 110 amps with 750 amp surge, allowing you to control battery disconnect from a small, remotely mounted switch in the cabin or trunk. The system works with their Lifeline memory retainer to keep radio and EFI presets in place—a critical feature for modern fuel-injected engines and computerized systems that would otherwise lose calibration data during power cycling.
Built for Restoration and Custom Applications
American Autowire has become the premier automotive electrical manufacturer for OEM/Restoration, Modified Restoration, and Street Rod/Custom vehicles. Their battery disconnect switches integrate seamlessly with their broader product ecosystem, which includes over 9,000 wiring harness combinations in the Factory Fit line and complete Classic Update Series kits. Whether you're maintaining period-correct authenticity on a concours restoration or building a modern pro-touring machine, these switches deliver the reliability and amperage capacity serious builders demand. Every component is hand-built at their Bellmawr, New Jersey facility, ensuring quality control that mass-produced imports simply cannot match.
Why Battery Disconnects Matter
A quality battery disconnect switch serves multiple critical functions in any automotive electrical system. It provides theft deterrence by rendering the vehicle inoperable, prevents parasitic battery drain during storage, offers emergency shutdown capability in case of electrical fire or accident, and meets tech inspection requirements for many racing sanctioning bodies. For classic cars with older wiring that may develop shorts, a battery disconnect switch can literally prevent your restoration investment from going up in flames. American Autowire's switches are designed with these real-world concerns in mind, featuring robust construction that stands up to repeated cycling and environmental exposure.
