HD Blade Type Ignition Switch w/Terminals

The HD Blade Type Ignition Switch w/Terminals from American Autowire is a four-position ignition switch designed for automotive electrical systems requiring a reliable blade-connector interface. Built with aluminum construction and featuring 1/4-inch blade connectors, this switch provides straightforward, dependable ignition control for custom wiring harnesses, restoration projects, and performance automotive builds where standardized ignition components are required.

The four-position design accommodates OFF, ACC (Accessory), ON, and START functions—the standard logic for automotive ignition circuits. Square key operation ensures consistent, repeatable engagement without wear-related looseness. The 1/4-inch blade connectors are industry-standard terminals that accept push-on spade connections, simplifying harness assembly and replacement compared to proprietary connector types. Natural aluminum finish resists corrosion under normal underhood conditions while maintaining a clean appearance in engine bays or interior installations.

This switch is suited for custom automotive builds, classic car restoration, hot rod wiring harnesses, and situations where OEM ignition switches are unavailable or incompatible with aftermarket electrical architectures. Builders and restorers value American Autowire components for their straightforward engineering and widespread compatibility with common wiring standards. The blade-connector design simplifies troubleshooting and allows terminations to be made without soldering, a practical advantage in field repair and modular harness layouts.

Weighing 0.36 pounds and measuring 2.5 x 2 x 3 inches, the HD Blade Type switch offers compact dimensions suitable for tight mounting spaces while remaining accessible for operation. Whether wired into a complete harness kit or retrofitted into an existing system, this switch delivers the four-position functionality fundamental to safe, controllable engine starting and accessory power management.
