Key benefits Protects your battery during storage or long periods of inactivity by fully disconnecting the battery from the vehicle electrical system. Improves safety by preventing parasitic drains, reducing the risk of accidental power draw or electrical faults when the vehicle is unused. Simple, reliable control of the main battery circuit with a clearly labeled rotary switch—install as a main battery switch or auxiliary isolator. What it is A battery isolator switch with a tin-plated inner core and durable ABS plastic housing. Tin plating improves antioxidation and reduces discoloration of copper contacts, extending rust protection without compromising conductivity. How it solves problems Prevents battery drain and extends battery life when a vehicle, boat or RV is stored for weeks or months. Lets you quickly disconnect power for safe maintenance or when fitting accessories to avoid shorts and accidental starts. Acts as a straightforward theft-deterrent and electrical isolation point during transport or service. Key features Material: Tin-plated inner core for improved corrosion resistance; robust ABS plastic exterior for impact resistance and long service life. Function: Interrupts the vehicle battery’s power supply to isolate and protect the battery and vehicle electronics. Labels and operation: Clear ON/OFF switch markings for easy use; ON means open, OFF means closed—turn to the required position to achieve the desired switching state. Design: Compact, modern appearance that fits neatly into dashboards or battery compartments. Compatibility: Suitable for cars, buses, caravans, trucks, pickups, yachts and similar vehicles; designed to serve as a main switch or auxiliary isolator. Practical use scenarios Seasonal storage: Disconnect the battery on campers, classic cars or motorcycles before long-term storage to prevent discharge and prolong battery life. Maintenance and repairs: Use as a quick, safe isolation point during electrical work to prevent shorts and accidental power-on. Transport and layup: Isolate batteries on boats and trailers during transport or winter layup to reduce risk of drain and corrosion. Reliable, easy to install and straightforward to operate, this battery isolator switch provides a practical way to protect batteries and increase electrical safety across a wide range of vehicles.
