Blue Sea Systems M-Series 6011 Combination Switch

Blue Sea Systems 6011 Battery Switch This ON-OFF-COMBINE Battery Disconnect Switch is great for a single engine, plus trolling motor battery setup.  It is a Double Pole switch meant to simultaneously disconnect/isolate both batteries – “starting” and “trolling motor” at the same time, while still allowing a manual emergency parallel feature. During normal operation you’ll simply turn this Blue Sea 6011 battery switch from OFF to ON.  This will close both contacts labeled “2”, and both contacts labeled “1”, but will keep them isolated so your house loads do not draw down your starting battery.  No action is required to isolate banks when you turn your engine off. If your starting battery’s charge ever gets deplete too low, the yellow “combine batteries” position will allow you to easily parallel your trolling motor battery to (hopefully) crank your boat engine.  Simply turn it back to ON to isolate again. 6011 marine battery switch connections: Starting Battery – stud 1 Engine
