The switch is constructed of stamped brass for corrosion resistance in a marine environment and includes a five screw terminal electrical connection for wiring the ignition and solenoid (starter) circuits. Its ignition circuit is rated 15 amps at 12 volts DC, and the solenoid (start) circuit is rated 30 amps at 12 volts DC. A key detail for installers: the ignition (accessory) circuit is not activated when the key is turned to the solenoid (start) position, so accessories wired to that circuit will not draw power during cranking.\u003c\/p\u003e\u003cp\u003eThe switch uses a 13\/16 inch diameter long shaft designed for panels up to 1-1\/8 inch thick, and it does not include a cap. Two keys are included with each switch, and a blank replacement key (Sea-Dog 420399) is available separately if additional or replacement keys are needed. This switch is intended as a direct panel-mount replacement for helm stations using a magneto-style three position ignition switch of this shaft length and terminal configuration.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 420351-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Three Position Ignition Switch, Magneto Style\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Positions:\u003c\/strong\u003e Off, Ignition, Start\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Diameter:\u003c\/strong\u003e 13\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type:\u003c\/strong\u003e Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Panel Thickness:\u003c\/strong\u003e 1-1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e 5 Screw Terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap:\u003c\/strong\u003e No cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Circuit Rating:\u003c\/strong\u003e 15 Amps at 12 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolenoid Circuit Rating:\u003c\/strong\u003e 30 Amps at 12 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stamped Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeys Included:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.414 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514423618\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for helm panels using a magneto-style three position ignition switch with a 13\/16 inch long shaft and panel thickness up to 1-1\/8 inch.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo manufacturer cross-reference numbers are listed for this part.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat functions does the Sea-Dog 420351-1 ignition switch have?\u003c\/strong\u003e It has three positions: off, ignition, and start, making it a magneto-style switch rather than a four-position accessory switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the ignition circuit stay powered while cranking the engine?\u003c\/strong\u003e No. On the 420351-1, the ignition (accessory) circuit is not activated while the key is held in the solenoid (start) position.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the amperage rating of this switch?\u003c\/strong\u003e The ignition circuit is rated 15 amps at 12 volts DC, and the solenoid (start) circuit is rated 30 amps at 12 volts DC on the Sea-Dog 420351-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 420351-1 ignition switch made from?\u003c\/strong\u003e It is constructed of stamped brass, chosen for its corrosion resistance in marine helm applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size shaft does this switch use and what panel thickness does it fit?\u003c\/strong\u003e The 420351-1 uses a 13\/16 inch diameter long shaft designed for panels up to 1-1\/8 inch thick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many terminals does the switch have for wiring?\u003c\/strong\u003e Five screw terminals are provided for the electrical connections on this Sea-Dog ignition switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sea-Dog 420351-1 come with a key or cap?\u003c\/strong\u003e Two keys are included with the switch, but no cap is included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I get a replacement key for this ignition switch?\u003c\/strong\u003e Yes, a blank replacement key, Sea-Dog part 420399, is available separately for the 420351-1 switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this ignition switch weigh?\u003c\/strong\u003e The Sea-Dog 420351-1 weighs 0.414 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the 420351-1 and a four position ignition switch?\u003c\/strong\u003e The 420351-1 is a three position magneto-style switch (off, ignition, start), while a four position switch adds a separate accessory position;
