【TOP LEVEL & HEAVY DUTY】Made of brass material, this top post battery disconnect switch is corrosion-resistant and offers good conductivity. It is durably constructed for safe and reliable use.

【EASY TO INSTALL】The battery doctor knife switch for top post batteries can be adjusted into a vertical knife switch by using the bottom screw, making it easy to install and simple to use. By switching the knife, the power will be cut off.
