Benefits of the Top Post Knife Blade Master Switch:

  • Compatible with Top Post Terminal: We specifically design the knife-blade battery disconnect switch for top post terminal batteries. It is suitable for battery negative post only and can be used with 6v, 12v, and 24v car, truck, bus, RV, boat, and trailer batteries.
  • Top Level & Heavy Duty: We construct the switch using brass material, ensuring high corrosion resistance and excellent conductive performance. Our durable construction guarantees safety during usage.
  • Easy Installation: Installing this battery doctor knife switch for top post batteries is a breeze. We can adjust it into a vertical knife switch by using the bottom screw, making it easy for us to install and simple for us to use. We just need to switch the knife, and we will cut off the power.
  • Electricity Saving: This knife blade master switch serves as a means to isolate and secure the electrical system of the battery. When the vehicle or boat is not in use, it eliminates any power draw from the battery, preventing unwanted battery drain. This helps save electricity and also acts as a theft deterrent, as it prevents unauthorized use. We widely use it for car, truck, boat, RV batteries, and other electrical equipment’s batteries.
