The Blue Sea Systems 9003E e-Series battery switch provides simple and reliable single circuit power control for marine electrical systems. Designed to turn one battery bank on or off, it helps isolate electrical loads during maintenance or storage. Its compact footprint allows installation in tight spaces, while flexible mounting options support both surface and rear panel configurations. The switch is ignition protected for safe use in gasoline powered boat engine rooms. Tin plated copper terminal studs are designed to accept multiple cable connections and provide secure, low resistance contact. A textured knob and face enable operation in low light conditions. This model does not include an alternator field disconnect.
