It has a 13\/16 inch diameter long shaft, designed to pass through a panel up to 1-1\/8 inch thick, and terminates in four screw connections for wiring the ignition circuit, solenoid circuit, and accessory circuit. The switch is rated 15A at 12VDC for both the ignition and accessory positions, and 30A at 12VDC for the solenoid position, giving it enough capacity to handle a typical inboard or sterndrive cranking circuit.\u003c\/p\u003e\u003cp\u003eConstruction is polypropylene, a corrosion-resistant plastic that holds up to the marine environment better than metal switch bodies, and the screw-terminal version of this switch includes a rubber boot to help seal the back of the switch from moisture and spray. The switch ships with two keys and a cap. It is a direct helm replacement or new-install switch for boats needing a standard four position key switch with screw terminals; a four-blade-terminal version and a screw-terminal-only replacement cap are also offered separately as distinct part numbers if wiring style needs to differ.\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 420375-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Positions:\u003c\/strong\u003e Accessory - Off - Ignition - Start\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polypropylene\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 Length:\u003c\/strong\u003e 1-1\/8 inch (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 4 Screws\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Cap:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Circuit Rating:\u003c\/strong\u003e 15 Amps at 12VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolenoid Circuit Rating:\u003c\/strong\u003e 30 Amps at 12VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccessory Circuit Rating:\u003c\/strong\u003e 15 Amps at 12VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Two keys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 7.88 x 3.88 x 0.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.272 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514423670\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat are the four positions on the Sea-Dog 420375-1 ignition switch?\u003c\/strong\u003e The 420375-1 cycles through accessory, off, ignition, and start positions, covering the standard functions needed to power accessories, kill the circuit, run ignition, and crank the engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size shaft does this switch have?\u003c\/strong\u003e It has a 13\/16 inch diameter shaft in the long configuration, measuring 1-1\/8 inch, and is rated for a maximum panel thickness of 1-1\/8 inch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre the terminals screw type or blade type on part number 420375-1?\u003c\/strong\u003e This version uses four screw terminals.
