A compact battery switch that simplifies switching and offers multiple installation options. Simultaneously switches two isolated battery banks or combines battery banks to all loads.
Blue Sea Systems e-Series Dual Circuit Plus switches isolate your Start and House battery circuits, preventing accidental discharge of the starting bank and protecting your electronics from engine starting sags and spikes. Ideal when combined with an Automatic Charging Relay, which will automate charging while the Dual Circuit Plus will simplify the switching. In an emergency, this switch allows you to combine two battery banks in the ON position. The combine feature allows you to cross-connect your battery banks to start the engine or make a radio call.
The m-Series battery switches are compact and waterproof and can be installed in a variety of locations. A small footprint and 3 mounting options make installation easy. They are ignition protected and can be located in the engine rooms of gasoline powered boats. The one piece copper terminal studs are long and will accept multiple cables and the torque required to create a secure connection that minimizes resistance. Tactile textures on the face for knob position awareness by feel only. A removeable knob adds a level of security and provides a service lock-out when needed.
