About this item

【Heavy-Duty Electrical Performance】- This battery disconnect switch is engineered for high-demand applications, rated for 300A in 12V-48V DC systems. The heavy-duty master cutoff is constructed with solid brass terminals, ensuring maximum electrical conductivity and minimal power loss. This design makes the power cutoff switch a reliable component for any vehicle's electrical system.

【Negative Top-Post Compatibility】- Specifically designed for standard top-post batteries, this battery isolator switch fits securely on negative terminals with a 15-17mm diameter. The top-post kill switch integrates directly onto the battery post, creating a clean and effective power cutoff point. Please ensure the distance from the center of the negative post to any obstacle is greater than 12cm for proper clearance.

【Versatile Connection Options】- This battery terminal switch offers enhanced flexibility with two distinct wiring methods. The adjustable battery clamp can be oriented in multiple directions to best suit your cable routing needs. An additional M8 terminal stud is also included, allowing you to connect a secondary cable for accessories or an alternative ground path.

【Intuitive Rotary Operation】- Featuring a large, easy-to-grip rotary knob, this manual disconnect switch provides simple On/Off 2-position control. The rotary knob displays a clear green indicator for "ON" and red for "OUT/OFF," offering instant visual confirmation of the power status. A simple turn of the knob effectively isolates the battery to prevent parasitic drain.

【Broad Vehicle Application】- This universal battery cutoff switch is an ideal solution for a wide range of vehicles operating on 12V, 24V, or 48V DC systems. The master power switch is suitable for cars, boats, RVs, campers, trucks, and tractors. It serves as an essential safety and battery-saving device, perfect for periods of storage or maintenance.
