Sea-Dog Line

<p>For over a century, Sea-Dog Line has stood as a cornerstone of the marine hardware industry, delivering innovative solutions that meet the demanding needs of recreational and commercial boaters. Founded in the early 1920s by entrepreneur Hans "Action" Broson Sneve, the company began with a unique sales approach—showcasing marine hardware aboard a 55-foot cruiser that sailed from Alaska to Mexico. This hands-on philosophy continues to shape Sea-Dog's commitment to producing hardware that performs reliably in the harshest saltwater environments.</p><h3>Industry-Leading Marine Hardware Manufacturing</h3><p>Based in Everett, Washington, Sea-Dog Corporation operates a 75,000-square-foot warehouse stocking over 8 million parts and runs an injection molding facility with 16 machines producing more than 17 million components annually. The company's extensive product line spans anchoring systems, deck hardware, electrical components, plumbing fittings, and lighting solutions—all engineered with marine-grade materials like stainless steel, brass, and UV-resistant polymers. Sea-Dog's recognition as a multiple-time NMDA Supplier of the Year underscores the brand's excellence in both product quality and customer service, while their on-staff ABYC-certified marine technician provides invaluable installation and technical support.</p><h3>Premium Marine Components for Every Vessel</h3><p>Sea-Dog's <a href="/7549-sea-dog-line-windshield-washers-wipers-replacement-motors-201195">windshield washers, wipers, and replacement motors</a> deliver crystal-clear visibility during inclement weather, with both manual and electric options featuring corrosion-resistant stainless steel arms and UV-stable blades designed specifically for marine windshield applications. Their <a href="/7549-sea-dog-line-electric-horns-200351">electric horns</a> include the popular MaxBlast line, which passed rigorous 600-hour salt spray testing while meeting US Coast Guard COLREGS and ABYC standards for audible warning devices.

Product Details

The Sea-Dog Line 422730-1 is a compact mini battery switch designed for marine electrical systems requiring key-controlled power management. This single battery switch features a three-position key operation: On, Off, and Out (key removal), providing secure power control and theft deterrence for boats, marine electronics, and auxiliary power systems.

Key Features:

  • 32-volt DC maximum voltage rating for compatibility with standard 12V and 24V marine systems
  • 300-amp continuous current capacity handles high-draw applications
  • Three-position key switch: On/Off/Out (remove key) for security
  • Mini compact design saves space in tight console or panel installations
  • Durable marine-grade construction resists corrosion in harsh saltwater environments
  • Single battery configuration for simple electrical system setups

This battery switch is ideal for smaller vessels, personal watercraft, tenders, or auxiliary battery systems where space is limited but secure power control is essential. The removable key feature prevents unauthorized use and battery drain when the vessel is unattended.

These combi relays are getting rare someone needs to start making these things again.
