COZYEHOO introduces a compact, rugged battery disconnect switch designed for side post terminals. Built to handle 6V, 12V, and 24V systems, it offers a simple, reliable way to cut power when a vehicle, boat, or RV is idle. A quick flip of the knife blade creates a clear, instantaneous break in the circuit, which can help limit drain and simplify safety checks.

Key features at a glance

  • Compatible with side post negative terminals, suitable for a wide range of vehicles and equipment.
  • Robust brass construction delivers solid conductivity and corrosion resistance for long-term use.
  • Easy installation and operation — switch the knife to isolate power in seconds.
  • Power management that helps prevent battery drain and unauthorized use during storage or transit.

What this switch can do for you

  • Auto, truck, and RV users can quickly cut power to the electrical system when parked for extended periods.
  • Boat owners can secure the battery while docked or during seasonal layups without a complex setup.

With a peak rating up to 750A and a continuous rating of 250A, the switch handles demanding automotive and marine loads without bulky hardware. The brass main contact area enhances current flow while resisting moisture and salt exposure, making it a dependable accessory in mixed environments.

Installation is straightforward: connect to the side post terminal, then flip the knife to interrupt the circuit. The design keeps the process simple for DIY enthusiasts while fitting into tight engine bays, battery compartments, or electrical panels.

Quality and support matter. COZYEHOO backs this switch with a customer-focused approach, aiming to resolve issues quickly and keep your workflows smooth. If you are unsure about compatibility or mounting, reach out for guidance before purchase to ensure the best fit for your setup.
