Product Overview

Simultaneously switches two isolated battery banks. A compact battery switch that offers multiple installation options that will stand alone or can be integrated into a larger system. 

Blue Sea Systems e-Series battery switches can be installed in a variety of locations. A compact footprint and two mounting options make installation easy. They are ignition protected and can be located in the engine rooms of gasoline powered boats. The tactile texture of the switch face and knob allow operation by feel in low or no light situations. The one piece tin-plated copper terminal studs are long enough to accept multiple cables and will handle the torque required to create a secure connection that minimizes resistance.
