12V/24V 6pcs Pure Copper Battery Circuit Breaker Isolator Switch for Car 12V Compatible Terminals 16-18mm

This battery circuit breaker can effectively prevent leakage currents during long periods of downtime. With a simple rotation, the battery cut off interrupts the power supply and protects the battery from unnecessary discharge. It is ideal for small 12V vehicles and helps extend battery life. Made of pure copper with zinc alloy outer coating, this car circuit breaker provides excellent conductivity and strong corrosion resistance. Its solid structure ensures stable current transmission, reliable operation and durable attachment to the battery terminal. This 12V-24V battery isolator switch is designed to precisely fit the 16mm and 18mm inner diameter battery terminals. It ensures a firm and secure contact, compatible with many common 12V vehicles for a stable connection on a daily basis. The battery circuit breaker is controlled only by a rotary mechanism, without tools. One rotation turns the power off, another to restore it. This simple operation is particularly convenient for maintenance, extended parking or quick shutdown in case of emergency. This pack includes 6 battery cutters, ideal for equipping multiple vehicles or for professional use in the workshop. Each circuit breaker effectively protects against energy loss and is suitable for cars, motorcycles, small machines and other electrical equipment.
