The \u003cstrong\u003eBlue Sea Systems e-Series Dual Circuit Battery Switch\u003c\/strong\u003e solves this problem by allowing you to switch two isolated battery banks simultaneously with a single turn of the knob. This innovative design replaces the need for two separate switches, streamlining your dashboard or engine room layout while maintaining critical circuit separation.\u003c\/p\u003e  \u003ch3\u003eSimultaneous Switching for Isolated Banks\u003c\/h3\u003e \u003cp\u003eDesigned for dual-battery systems—typically a starting battery and a house battery—this switch ensures that both circuits are energized or disconnected at the same time. Crucially, it maintains isolation between the two banks. This means your sensitive electronics on the house circuit remain powered without risking the starting battery's charge, and engine starting spikes are kept away from your accessories. It offers a straightforward ON\/OFF mechanism that simplifies operation for boat owners and vehicle operators.\u003c\/p\u003e  \u003ch3\u003eIgnition Protected and Marine-Grade Durability\u003c\/h3\u003e \u003cp\u003eSafety is paramount in enclosed engine spaces and fuel lockers. This unit is \u003cstrong\u003eignition protected\u003c\/strong\u003e, making it safe for installation aboard gasoline-powered boats or vehicles where fuel vapours may be present. The case design allows for versatile mounting options, including surface or rear panel mounting, ensuring a clean installation regardless of your setup constraints.\u003c\/p\u003e  \u003ch3\u003eHigh-Current Handling and robust Connections\u003c\/h3\u003e \u003cp\u003eBuilt to handle significant electrical loads, this switch features a continuous rating of \u003cstrong\u003e350A\u003c\/strong\u003e and a cranking rating of \u003cstrong\u003e700A per circuit\u003c\/strong\u003e (30 seconds). It is engineered with \u003cstrong\u003etinned copper studs\u003c\/strong\u003e for maximum conductivity and corrosion resistance, essential for harsh saltwater environments.\u003c\/p\u003e \u003cp\u003eThe terminals are designed to accept large cables required for high-current applications:\u003c\/p\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eTerminal Stud Size:\u003c\/strong\u003e 3\/8\"-16 (Approx.
