Adopting a rotary design, when disconnecting or connecting the battery, simply follow the instructions on the switch and turn the battery switch to the \"on\" or \"off\" position to easily control the current, making the operation simple.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px; font-size: 13.5px; color: #333333; line-height: 1.7; text-align: justify;\"\u003e\n\u003cstrong\u003eSturdy Materials\u003c\/strong\u003e, Our car top post battery disconnect switch is made of high-quality copper material. Copper material has good conductivity, which can ensure stable current transmission, reduce energy loss, and effectively avoid vehicle circuit failures caused by poor contact. The sturdy copper material also has good resistance to pressure and wear, and can withstand frequent opening and closing operations, providing reliable protection for your vehicle's electrical system.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px; font-size: 13.5px; color: #333333; line-height: 1.7; text-align: justify;\"\u003e\n\u003cstrong\u003eWide Application\u003c\/strong\u003e, Our car top post battery disconnect switch has a height of 3.7 inch, a width of 1.18 inch for the clamp portion, and a diameter of 0.67 inch for the clamp opening. This roof pillar battery disconnect switch is suitable for cars, vehicles, and RVs with standard 15-17 millimeter tapered roof pillar terminals. Meanwhile, it is designed for a DC 12V system with a rated current of up to 400A.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px; font-size: 13.5px; color: #333333; line-height: 1.7; text-align: justify;\"\u003e\n\u003cstrong\u003eEasy Installation\u003c\/strong\u003e, The installation of our car top post battery disconnect switch is very simple. When installing, turn off the engine first, remove the negative pole of the battery and set aside the existing cable. After cleaning the battery terminal, install the battery switch onto the negative terminal and tighten it. Finally, fix the negative cable of the battery to the \"male\" end of the switch with bolts and tighten it. Check that the connection is secure.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px; font-size: 13.5px; color: #333333; line-height: 1.7; text-align: justify;\"\u003e\n\u003cstrong\u003eStable Structure\u003c\/strong\u003e, our car top post battery disconnect switch is fixed with screws, which can make the main body and bottom plate of the switch more tightly connected, making the overall structure more stable.
