Cole Hersee Ignition Switches

Cole Hersee Ignition Switches: Proven Reliability for Critical Starting Systems

When it comes to ignition switches that deliver decades of dependable service, Cole Hersee has established itself as a trusted name in both automotive and marine electrical applications. Cole Hersee ignition and magneto switches are available with two, three, and four position circuitry and can be used for energizing any appropriate low voltage application, making them versatile solutions for everything from heavy-duty trucks to recreational marine vessels.

What sets Cole Hersee apart in the ignition switches category is their attention to security and actuation options. They are actuated by a coded key and tumbler lock, patented Hecol™ keyed lock, Delco keyed lock, or a lever. This range of locking mechanisms allows technicians and vehicle owners to choose the security level and actuation style that best matches their application—whether it's individually coded cylinder locks for anti-theft protection or non-tumbler Hecol systems for environments where traditional keys may be impractical.

Engineered for Demanding Environments

Cole Hersee ignition switches are built to withstand challenging conditions. Many models feature threaded stem mounting in various sizes (3/4-20, 13/16-24, and 1"-24 configurations), threaded tab terminals with screw connections for secure wire attachment, and O-ring seals to protect against moisture intrusion. These design elements make Cole Hersee ignition switches particularly well-suited for marine applications where exposure to water and vibration is constant, as well as for construction equipment, agricultural machinery, and commercial vehicles that operate in harsh outdoor environments.

Versatile Position Configurations

The flexibility of Cole Hersee's ignition switch lineup addresses a wide range of circuit requirements. Two-position models provide simple on-off control, while three-position switches typically offer Off-On/Acc-Start functionality for standard vehicle applications. Four-position switches add accessory circuit control with configurations like Acc-Off-On/Acc-Start, allowing operators to power accessories without engaging the ignition. Current ratings are application-specific, with typical configurations handling 10 amps for accessory and ignition circuits and 5 amps for starting circuits, though this varies by model.

Application Expertise Across Industries

While Cole Hersee ignition switches are commonly specified for marine installations—where their corrosion-resistant construction and reliable coded locking mechanisms provide peace of mind—they're equally at home in heavy equipment, emergency vehicles, agricultural machinery, and recreational vehicles. The availability of lever-actuated models alongside keyed versions gives equipment manufacturers options for applications where keyless operation is preferred, such as stationary industrial equipment or applications requiring quick emergency shutdown capabilities.
