The 3-position action — Off, Ignition, and Start — gives you clean, positive control over engine startup and shutdown from the helm. A polyester housing provides maximum corrosion protection and eliminates the risk of shorts in the demanding marine environment, while an inner seal between the cylinder keeps moisture out of the switch mechanism.\u003c\/p\u003e\u003cp\u003eThe push-to-choke function and included boot make this a complete, ready-to-install solution. The 5\/8\" mounting diameter and 7\/8\" mounting hole fit a wide range of marine dash panels, and the 5-screw plus 1-boss terminal layout accommodates standard magneto wiring configurations.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 11-MP39760\u003c\/li\u003e\n\u003cli\u003eSwitch Type: 3-Position (Off – Ignition – Start)\u003c\/li\u003e\n\u003cli\u003eIgnition Type: Magneto\u003c\/li\u003e\n\u003cli\u003eVoltage: 12V DC\u003c\/li\u003e\n\u003cli\u003eCurrent Rating: 15A\u003c\/li\u003e\n\u003cli\u003eSolenoid: 30A\u003c\/li\u003e\n\u003cli\u003eCylinder Diameter: 5\/8\"\u003c\/li\u003e\n\u003cli\u003eMounting Hole: 7\/8\"\u003c\/li\u003e\n\u003cli\u003eTerminals: 5 Screw + 1 Boss\u003c\/li\u003e\n\u003cli\u003eHousing Material: Polyester (corrosion-resistant)\u003c\/li\u003e\n\u003cli\u003eIncludes: Push-to-choke, boot, lock and contact plate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOutboard and inboard engines with magneto ignition systems\u003c\/li\u003e\n\u003cli\u003eMarine helm panels with a 7\/8\" mounting hole\u003c\/li\u003e\n\u003cli\u003e12V DC electrical systems requiring a 3-position Off\/Ignition\/Start switch\u003c\/li\u003e\n\u003cli\u003eReplacement for worn or damaged OEM ignition switches on magneto-equipped engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe MP39760 is the right choice when you have a magneto ignition engine and need a compact 5\/8\" cylinder switch with push-to-choke — common on older outboards and smaller inboards. The polyester housing is the preferred material for saltwater and high-humidity environments over brass alternatives.
