This battery knife switch isolates and secures your vehicle’s electrical system while providing a reliable, long-lasting connection. Built from high-quality brass and designed for easy, tool-free operation, it prevents battery drain during storage or maintenance and maintains strong electrical performance for DC 12V–24V systems. Key benefits Prevents battery drain: Quickly disconnect the battery to stop parasitic draw when your vehicle is not in use. Safe, quick power cut-off: Isolate the electrical system for safe maintenance or temporary shutdown. Reliable conductivity: Brass construction offers excellent electrical conductivity, lowering voltage distortion and transmission loss. Durable and corrosion-resistant: Brass resists rust and corrosion for long service life in automotive and marine environments. Easy to use: Top-post, vertical knife-blade design enables tool-free operation—lift the blade to cut power, push down to reconnect. Features Material: High-quality brass for durability, corrosion resistance, and stable electrical contact. Design: Top-post vertical knife-blade main switch for fast, intuitive operation and straightforward installation. Compatibility: Universal for DC 12V–24V systems; suitable for a wide range of vehicles and electrical equipment. Function: Battery isolation switch to reduce power consumption, enable temporary power-off during maintenance, and secure the electrical system. Typical applications Seasonal storage: Disconnect a car, RV, or ATV battery during winter storage to prevent discharge and avoid a dead battery at startup. Routine maintenance: Safely cut power before working on electrical components, reducing risk of shorts or accidental drain. Marine and off-road use: Quickly isolate power on boats, marine equipment, or ATVs between trips to protect batteries and electronics. What you can expect Simple, reliable operation without tools. Compatibility with most cars, boats, trucks, RVs, ATVs, and other DC 12V–24V electrical devices. Long-term performance thanks to brass construction and secure knife-blade contacts. This switch offers a practical, durable solution for controlling and protecting your vehicle or equipment battery with minimal effort.
