It uses a locking ring with a lever seal and a protruding cap nut to resist water penetration at the panel face, making it suitable for helm stations, consoles, and other exposed-to-spray locations aboard a boat. The switch is rated 15A at 12VDC, covering common marine circuits such as cabin lights, bilge pumps, accessories, and other single-pole on\/off applications.\u003c\/p\u003e\u003cp\u003eConstruction is stamped brass, injection molded nylon, and polycarbonate, giving the switch body and toggle strong resistance to moisture and everyday wear in a marine environment. It is a 2-blade SPST design, meaning it simply opens and closes a single circuit with no momentary or center-off function, and it mounts through a standard panel cutout using its threaded bushing and cap nut. Overall dimensions are 4.94 x 1.88 x 1.25 inches, and the switch weighs 0.056 pounds. This is a straightforward, drop-in replacement or new-install switch for boat owners and marine electricians wiring or upgrading a 12V DC panel.\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 420101-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit:\u003c\/strong\u003e SPST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e On\/Off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 2 Blades\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmps:\u003c\/strong\u003e 15A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolts:\u003c\/strong\u003e 12V\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\u003eProduct Dimensions:\u003c\/strong\u003e 4.94 x 1.88 x 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.056 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514420754\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal fit for standard marine panel cutouts on 12V DC electrical systems; no make\/model-specific fitment restrictions are specified.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat type of switch is the Sea-Dog 420101-1?\u003c\/strong\u003e It is an SPST On\/Off toggle switch, meaning it controls a single circuit with a simple on or off action and no momentary or center positions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the amperage and voltage rating?\u003c\/strong\u003e The 420101-1 toggle switch is rated 15A at 12V, suitable for standard 12V DC marine circuits like lighting, pumps, and accessories.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this toggle switch waterproof?\u003c\/strong\u003e It is water resistant rather than fully submersible, using a locking ring with a lever seal and a protruding cap nut to resist water penetration at the panel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sea-Dog 420101-1 made from?\u003c\/strong\u003e The switch is constructed of stamped brass, injection molded nylon, and polycarbonate for corrosion resistance in a marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many terminals does this switch have?\u003c\/strong\u003e The 420101-1 has 2 blade terminals, consistent with its SPST On\/Off circuit design.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of this switch?\u003c\/strong\u003e The Sea-Dog toggle switch measures 4.94 x 1.88 x 1.25 inches overall.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the switch weigh?\u003c\/strong\u003e The 420101-1 weighs 0.056 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this switch fit any boat's electrical panel?\u003c\/strong\u003e Yes, the 420101-1 is a standard toggle switch designed to mount into a typical panel cutout on 12V DC marine electrical systems, with no make or model restrictions specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between this switch and Sea-Dog's SPDT toggle switches?\u003c\/strong\u003e The 420101-1 is a single-pole (SPST) On\/Off switch with 2 blade terminals, while Sea-Dog's SPDT models are On\/Off\/On switches with 3 blade terminals for controlling two circuits or directions from one switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this switch include a mounting nut?\u003c\/strong\u003e The 420101-1 toggle switch has a protruding cap nut and locking ring built into its design for panel mounting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sea-Dog 420101-1 genuine Sea-Dog product?\u003c\/strong\u003e Yes, the 420101-1 is a genuine Sea-Dog branded marine toggle switch, not a generic aftermarket part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this switch?\u003c\/strong\u003e The Sea-Dog 420101-1 toggle switch carries UPC 035514420754.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988772532443,"sku":"S-D-420101-1","price":5.87,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/4976_76405e68-c036-47f1-acbb-d29f4b05e643.jpg?v=1784429142","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-420101-1-spst-on-off-toggle-switch-water-resistant-15a-12v-marine-boat-switch","provider":"Good Vibes Marina","version":"1.0","type":"link"}
