2 Pcs 12V-24V Car Battery Power Cut-Off Switch Breaker Fit for Truck Boat Rv Car Supplies, Heavy Duty Battery Shut Off Disconnect Smart Switch, Pure Copper Stable Transmission High Conductivity

Take Full Control of Your Vehicle's Electrical System with a Heavy Duty Battery Disconnect Switch Whether you're storing a vehicle for the season, performing maintenance, or adding an extra layer of security, this smart disconnect switch delivers uncompromising performance Wide Voltage Compatibility for Multiple Applications Cars & SUVs – Prevent battery drain during long term storage Trucks & Heavy Vehicles – Handle higher current demands with ease Boats & Marine Vessels – Eliminate parasitic draw from onboard electronics RVs & Campers – Preserve house battery charge between trips Construction & Farm Equipment – Add a quick safety kill for maintenance Pure Copper Core – The Heart of Stable Transmission This unit features a pure copper internal conductor: Superior electrical conductivity – Minimizes voltage drop across the switch Lower operating temperature – Reduced resistance means less heat buildup under load Long term corrosion resistance – Maintains clean contact pressure even in humid or salt air environments (boats, coastal RVs) Heavy Duty Construction for Demanding Environments The housing is impact resistant and insulated, while the internal contact mechanism is rated for repeated high current interruptions Unlike cheap plastic core switches that crack or melt This heavy duty unit maintains its structural integrity under engine bay heat, vibration, and moisture Smart, Simple Operation Rotate to the OFF position – instantly cuts all battery power Rotate to ON – restores full current for starting and operation

• Wide Voltage Compatible Design: Supports a wide voltage range of 12V to 24V, suitable for battery systems of automobiles RVs ships and various heavy vehicles, meeting the electrical isolation requirements of multiple power platforms
• Pure Copper Structure: The key conductive components inside the switch are made of pure copper material, which has excellent conductivity and low resistance characteristics. When high current passes through, the heat generation is low, which can stably transmit electrical energy and ensure the normal operation of vehicle start-up and electrical equipment
• Rotary Switch: The switch adopts a rotary on-off control design, which can quickly cut off or restore the connection between the battery and the vehicle circuit by rotating. Clear and precise operation feel, suitable for quickly disconnecting power during long-term parking, maintenance, or emergency situations
• Anti Corrosion Sealing Shell: The shell is made of materials and has splash proof and anti-corrosion properties, suitable for stable operation in humid vibration environments such as engine compartments and cabins
• Terminal Design: Standard specification terminals are pre installed on both sides of the switch, with adjustable angles and the ability to connect battery terminals and vehicle main cables as needed, without the need for crimping terminals or welding wire ends. By tightening the matching nut, the electrical connection can be completed, which is suitable for car owners to use basic tools for self installation
