Battery Disconnect Switch

📌 Product Overview

The Battery Disconnect Switch (Battery Cut-off / Master Switch) is a reliable safety device installed between the vehicle's battery and its electrical system, allowing the battery to be completely disconnected with a simple turn. It prevents battery drain during storage, parasitic power loss, electrical short circuits, and the risk of fire, while also serving as a convenient anti-theft measure. Widely used in cars, trucks, RVs, boats, and heavy equipment, it's an essential accessory for safety, security, and battery longevity.

This product is designed for independent e-commerce sales, suitable for OEM replacement, aftermarket upgrading, and bulk wholesale distribution.

✨ High-Quality Core Advantages

1. Heavy-Duty Construction for High Current

Manufactured with high-purity copper conductor contacts and a reinforced molded housing, it safely handles continuous current ratings of 200A–500A with minimal voltage drop and heat build-up — dependable for trucks, SUVs, and heavy-duty applications.

2. Precision Contact, Low Resistance

The silver-nickel plated contacts ensure low electrical resistance, efficient current flow, and high corrosion resistance for stable, long-term conductivity that won't degrade over time.

3. Arc-Suppression Design for Safe Operation

An optimized contact-break mechanism quickly extinguishes electrical arcs during disconnection, reducing contact wear, sparking, and overheating — extending service life and improving safety.

4. Durable & Weather-Resistant Housing

Built from flame-retardant, impact-resistant engineering plastic (UL94 V-0), it withstands vibration, moisture, and temperature extremes from -40℃ ~ +120℃, making it suitable for automotive, marine, and outdoor applications.

5. 100% Factory Tested — Quality Assured

Every switch undergoes contact resistance, load current, and insulation testing before shipment, guaranteeing a 100% pass rate and backed by after-sales quality warranty.
