## Overview

The Blue Sea Systems m-Series On/Off Battery Switch is a compact, ignition-protected rotary switch designed for marine and DC-powered applications. Rated for up to 375 amps intermittent and 48 volts, it features versatile mounting options, durable tin-plated copper studs for secure multi-cable connections, and a removable knob to prevent accidental current flow. Engineered for tight spaces and harsh environments, it ensures safe, reliable battery control in gasoline engine compartments.

## Description

This compact battery switch is designed to manage a single battery connected to a single load group and supports flexible installation in a variety of panel or engine room layouts. Its small footprint and three available mounting options make it suitable for areas with limited space. The switch includes ignition protection for use in gasoline powered engine compartments, allowing safe placement in locations that require protected components. The tactile surface of the switch face and the removable knob help support operation in low light conditions and contribute to preventing unintended power flow during electrical system service. Tin plated copper terminal studs are built as a single piece and provide sufficient length for connecting multiple cables while supporting secure fastening. With its combination of protective features, connection capacity, and adaptable mounting options, this switch offers a practical solution for managing basic battery control needs in marine electrical systems.

Review: Rock-Solid, High-Quality Battery Switch You Can Trust - The Blue Sea Systems 6006 m-Series ON/OFF Battery Isolator Switch is exactly what you want in a critical electrical component: simple, reliable, and built to last. The build quality is outstanding — solid terminals, smooth but positive switching action, and materials that clearly hold up in a marine environment. Installation is straightforward, and the compact m-Series design makes it easy to fit even in tight battery compartments. What really stands out is the confidence it gives you. When it’s OFF, it’s truly OFF. When it’s ON, you know your system is connected without voltage drop or fuss. It handles high current loads effortlessly and stays cool under use. Typical Blue Sea attention to detail shows through: clear labeling, removable knob for safety, and excellent corrosion resistance. This is one of those products you install once and then never think about again — which is exactly what you want for a battery isolator. If you’re upgrading or replacing a battery switch, don’t hesitate. The 6006 is worth every penny and sets the standard for marine electrical hardware. Highly recommende
Review: Great disconnect! - Used this as a disconnect for my jeeps 12k badlands winch and it works great! Badlands uses a thermal disconnect but it was rusted and needed to be replaced. I could not find a direction replacement from badlands so after some homework i found this. Mounted it next to my battery up out of the way and so far so good. Its nice and strong, installation was relatively simple. I would definitely recommend this if you need to replace or upgrade your winch disconnect.
