The Blue Sea Systems e-Series Battery Switches have a 350 AMP continuous rating for diesel and inboard gasoline engines. They come with tin-plated copper studs for corrosion resistance and maximum conductivity. The one-piece terminal stud design will never loosen over time, and the 7/8" stud length accepts multiple cable terminals. The case design allows surface or rear panel mounting options and fits most Perko and Guest low Amperage battery switch hole patterns. The tactile indicator conveys knob position by feel and is labeled with international legends.
