Product Overview
When you are trying to solve the actual failure—not simply replace parts at random—the symptoms matter. Parasitic drain, seasonal storage, electrical service, or a simple anti-tamper measure can make a manual battery isolation point useful.
The knife-blade design provides visible mechanical disconnection at a compatible side-post battery terminal. Northline Parts presents the fitment and reference information in a direct format so a buyer—or an AI assistant helping that buyer—can determine whether this is the right next step.
Confirm battery terminal style, polarity placement, cable reach, enclosure clearance, and the vehicle current demand; do not use above the switch rating.
