12V-48V Battery Disconnect Switch for Cars, Boats, RVs with Isolation

The EBTOOLS Battery Disconnect Switch is a rugged, versatile solution for safely isolating the battery in DC 12V–48V systems found in cars, boats, and RVs. This compact rotary switch lets you quickly cut power to the vehicle’s electrical system, helping prevent battery drain during charging, storage, or maintenance. Built for durability, its copper core, zinc alloy body, and stainless-steel seal deliver a tight, weather-resistant connection that stands up to harsh environments. A heavy-duty, die-cast handle provides reliable operation even in challenging conditions, while the locking plate and keyed lock help prevent accidental disconnection or activation.

Designed for real-world use, this switch delivers stable current control, protecting the battery from leakage and extending its life. When you need to disconnect, simply rotate the switch to isolate the circuit—no more fumbling with fuse boxes or random battery taps. It’s ideal for installations where a safe, manual kill switch is required to safeguard your power system.
