Product Overview

A compact battery switch that offers multiple installation options and is full of features. 

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. Some models feature 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. Choose between 2 or 4 positions to match the needs of your boat. 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.
