Gioyonil Battery Disconnect Switch 12-48V Master Power Cut Isolator – 275A, 2-Pack

Reliable DC Power Isolation for Your Vehicle, Boat, and RV

Power systems on the move demand a switch that feels sturdy and works when you need it. The Gioyonil Battery Disconnect Switch is built for 12-48V DC networks, giving you a straightforward way to isolate an entire battery bank or electrical run. Whether you’re preparing for a long camping trip or fine-tuning a boat’s electrical setup, this device helps you manage power without clutter.

Durable, purpose-built for rugged environments

Engineered with a tinned copper core and ABS plastic, the switch resists corrosion and stands up to vibration. Stainless steel mounting screws and caps ensure a secure fit, while a removable rear cover insulates the rear terminals to guard against accidental shorts. The construction is designed for repeated use in varied conditions, from dusty campsites to salt-tinged docks.

• Sturdy materials stand up to road dust, salt air, and frequent use
• Removable rear cover minimizes short circuits during maintenance

Safe, configurable power control

The unit is simple to operate with two positions: Off (0) and On (1). It’s rated for DC 12V systems with 275A continuous, 455A intermittent, and 1250A momentary capacity, making it suitable for a range of setups. Terminal studs measure 2x3/8" (10mm), supporting larger gauge cables as needed. Four removable side plates provide access for up to 1/0 cables, enabling tidy wiring and flexible routing.

• Simple on/off control for easy power management
• Wide electrical specs offer a flexible fit for different setups

Versatile, ready-to-use in multiple environments

Widely used across cars, marine boats, RVs, campers, travel trailers, trucks, ATVs, UTVs, and other electrical systems, the isolator switch can be used alone or paired with other switches for expanded power management. The package includes 2 switches and 8 mounting bolts, helping you plan a clean, efficient install. A 12-month warranty adds confidence when you’re outfitting your vehicle or workspace.

In practice, you might deploy the Gioyonil switch near the battery bank to quickly isolate power before maintenance, or lock it with a companion switch to manage complex electrical builds. While outcomes can vary by setup, the device is designed to offer reliable control and straightforward integration.

What you get and why it matters

Two switches deliver redundancy for critical circuits, plus mounting hardware for faster installation. By enabling deliberate power separation, you can reduce parasitic drain and protect sensitive electronics when the vehicle is idle, helping you preserve battery health over time.

Note: This product is designed to work with DC 12-48V systems and is intended to be part of a broader power management strategy rather than a guaranteed solution for every scenario.
