Sea-Dog Brass 3-Position Key Ignition Switch

The Sea-Dog Brass 3-Position Key Ignition Switch is essential for reliable engine start systems in both recreational and commercial marine vessels. Boaters understand that ignition integrity is crucial for on-water reliability and safety. This switch is designed to handle the transitions from off to accessory to on, ensuring effective power distribution to your engine's starter and electrical systems.

Constructed from heavy-duty brass, this ignition switch offers superior corrosion resistance, particularly in salt-water environments where standard steel components may fail. Its three-position design allows for intuitive control and electrical isolation when the engine is off, which helps reduce parasitic battery drain during extended storage. The brass contacts provide low resistance and reliable arc suppression, meeting the high-amperage demands of engine starting.

This Sea-Dog unit is a direct fit for most inboard and outboard installations that require OEM brass ignition switches. Boaters replacing worn or corroded original switches will appreciate the solid construction and tight switching tolerances that minimize intermittent contact issues. Installation requires basic marine electrical knowledge, making it accessible for most boat owners.
