Ignition/Starter Switch

The Ignition/Starter Switch by Longacre is a precision electrical component engineered for race cars, performance vehicles, and custom builds where reliability under extreme conditions is non-negotiable. Whether you're wiring a dedicated track machine, a street rod, or swapping in an aftermarket ignition system, this switch provides the robust electrical control needed to reliably manage starter motor engagement and ignition circuits. Designed for builders and enthusiasts who demand consistency lap after lap or mile after mile, the Longacre ignition/starter switch eliminates weak points in factory wiring harnesses and OEM components that can falter under high amperage demand.

This switch features a compact, lightweight design—weighing just 0.29 lbs with dimensions of 6.5 x 1.05 x 8.9 inches—making it ideal for tight engine bays and custom fabrication scenarios where space is at a premium. The electrical contacts are engineered to handle the sustained amperage loads that modern high-output starters and ignition systems demand, with durable construction that resists corrosion and vibration fatigue common in race and modified vehicles. The switch's straightforward wiring interface simplifies integration into standalone ignition systems, custom harnesses, and hot rod applications where you need direct, dependable control over engine start and ignition functions without relying on complex factory modules.

Performance builders, race teams, and automotive fabricators trust Longacre components for applications ranging from circle track racing to street performance builds and full restoration projects. This ignition/starter switch is particularly valuable when upgrading a vehicle's electrical architecture—such as during an engine swap, turbocharger installation, or transition to a programmable ECU—where OEM switch ratings may be insufficient. Installation is straightforward for anyone with basic automotive electrical knowledge, making it accessible whether you're working in a professional shop or a home garage. Compatible with both 12-volt systems and various ignition architectures, the Longacre switch provides the electrical integrity that separates a reliable build from one prone to no-start gremlins.
