The three-position action lets you control two separate circuits from a single switch, or reverse a motor or accessory, making it a common choice for bilge pumps, trim tabs, navigation lights, and other 12 volt onboard equipment. It is rated for 15 amps at 12 volts DC and uses a 3-blade SPDT contact configuration.\u003c\/p\u003e\u003cp\u003eThe switch is constructed of stamped brass, injection molded nylon, and polycarbonate for durability in a marine environment. A locking ring with a lever seal helps resist water penetration around the mounting hole, and the protruding cap nut design makes the switch easy to grip and actuate even with wet or gloved hands. Terminals are sized at 3\/8 inch and 1\/2 inch for secure wire connection, and installation is straightforward for anyone rewiring or upgrading a helm or accessory panel.\u003c\/p\u003e\u003cp\u003eSea-Dog Line has manufactured marine hardware and electrical components since 1933, and this toggle switch is sold individually for boat builders, riggers, and DIY boat owners replacing a worn or failed switch or adding a new circuit.\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 420108-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type:\u003c\/strong\u003e Toggle Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Action:\u003c\/strong\u003e On\/Off\/On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e SPDT (Single Pole Double Throw)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Blades:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 15 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Size A:\u003c\/strong\u003e 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Size B:\u003c\/strong\u003e 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Surface Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stamped Brass, Injection Molded Nylon, Polycarbonate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.058 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514423205\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does SPDT On\/Off\/On mean on this switch?\u003c\/strong\u003e SPDT On\/Off\/On describes a single pole double throw contact with three positions: one energized position, a center off position, and a second energized position, so the Sea-Dog 420108-1 can control two separate circuits or two directions from one switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this toggle switch waterproof?\u003c\/strong\u003e The Sea-Dog 420108-1 is water resistant rather than fully submersible, using a locking ring with a lever seal around the mounting hole to resist water penetration in a marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the amperage and voltage rating?\u003c\/strong\u003e This switch is rated for 15 amps at 12 volts DC, suitable for typical 12 volt marine circuits such as pumps, lights, and small accessories.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat terminal size does this switch use?\u003c\/strong\u003e The Sea-Dog 420108-1 has 3\/8 inch and 1\/2 inch spade terminals for wire connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the switch made from?\u003c\/strong\u003e It is constructed of stamped brass, injection molded nylon, and polycarbonate, chosen for corrosion resistance in a marine setting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this switch weigh?\u003c\/strong\u003e The Sea-Dog 420108-1 toggle switch weighs 0.058 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this switch include an illuminated position indicator?\u003c\/strong\u003e No, the 420108-1 is a standard (non-illuminating) toggle switch;
