Product Overview

A compact battery switch that offers multiple installation options. Switches isolated battery banks to all loads or combines battery banks to all loads. 

Blue Sea Systems e-Series battery switches can be installed in a variety of locations. Their 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. This version does not include an alternator field disconnect to protect the alternator diodes from damage if the switch is accidently turned to the OFF position while the engine is running.

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 accept the torque required to create a secure connection that minimizes resistance.
