2-Pack Top-Post Battery Disconnect Switch – Pure Copper Terminals, Adjustable & Waterproof, 12V/24V High Conductivity Isolator for Car, RV, Boat & Truck

Parts List: 2 x Battery Disconnect Switch Highlight 【Plug-and-Play Installation for Universal Fit】Engineered specifically for 16–17mm battery terminals (negative post), this switch installs directly without extra cables or adapters. Features 360° rotatable pure copper terminals to adapt to any wiring angle, plus top-post mounting design for secure battery connection. Includes gaskets and wrench for DIY-friendly, tool-free setup—perfect for beginners and pros. 【Prevents Parasitic Drain, Extends Battery Life Up to 30%】A simple 90° flip disconnects power instantly when vehicles are idle. Stops parasitic drain (voltage leaks from electronics), preserving battery health and extending service life by up to 30%. Reduces jump-starts, maintenance costs, and unexpected failures. 【IPX7 Waterproof & Heavy-Duty Performance】Marine-grade sealed housing blocks rain, saltwater, and humidity (IPX7 certified). Built with flame-retardant ABS + high-purity copper conductors for spark-resistant operation. Handles continuous 12A @ 275V, 455A intermittent, and 1,250A transient surges. Safe for 12V–48V DC systems in extreme conditions. 【Visual Safety Lock for Emergency Power Cutoff】Raised = OFF (90°), Lowered = ON (90°)—no guessing. Acts as a main battery isolator, emergency kill switch, or maintenance safety lock. Instantly cuts power to prevent shorts, sparks, or electrical fires during repairs or emergencies. 【Multi-Application Protection for All 12V/24V Systems】Universally compatible with cars, trucks, RVs, boats, ATVs, and marine vehicles. Physically isolates batteries to avoid depletion during storage, saving replacement costs. One switch, total peace of mind—no more dead batteries or costly service calls.
