Cole Hersee 4 Position General Purpose Ignition Switch

The Cole Hersee 4 Position General Purpose Ignition Switch (MPN 9579-BP) is a universal rotary-design electrical switch engineered for compact installation in vehicles, watercraft, and off-road equipment where space and reliability are critical. This 4-position switch handles ignition sequencing with a straightforward mechanical design that eliminates unnecessary complexity while delivering dependable performance in demanding field conditions.

Built with Cole Hersee's reputation for marine-grade and automotive electrical components, this switch features a rotary contact mechanism rated for general-purpose ignition and start circuit control. The compact footprint—3 inches long, 2 inches wide, and weighing just 0.2 lbs—allows integration into tight dashboard or panel spaces common in custom vehicle builds, marine electronics installations, and equipment retrofits. The 4-position configuration provides discrete switching states for off, accessory, ignition run, and starter engagement, making it suitable for both 12-volt and standard automotive electrical systems.

This switch is preferred by vehicle restorers, custom fabricators, and marine technicians who require OEM-quality ignition control without integrated steering column security features. Its universal design accommodates aftermarket dashboard layouts, classic vehicle restorations, and specialized equipment where manufacturers' original switches may be unavailable or incompatible. The mechanical rotary design resists electronic failure modes and suits environments where corrosion resistance and mechanical durability outweigh digital switching complexity.

Cole Hersee ignition switches serve the automotive electrical aftermarket, marine sector, and industrial equipment segments. This 4-position model stands apart from steering column-integrated modern switches by offering straightforward installation and replacement capability—a decisive advantage in restoration projects and equipment designs where original switch assemblies are obsolete or cannot be sourced.
