This Bluewater ON-OFF-COMBINE Battery Switch is great for a single engine + house battery setup. It is a Double Pole switch meant to simultaneously disconnect/isolate both batteries – “starting” and “house” – at the same time, while still allowing a manual emergency parallel feature.
During normal operation, you’ll simply turn this 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 depleted, the yellow “combine batteries” position will allow you to easily parallel your house battery to (hopefully) crank your engine. Simply turn it back to ON to isolate again.
Our Bluewater ON-OFF-COMBINE battery switch is made for the marine environment with tin-plated copper contacts and studs inside and out. We really love the yellow labeling on this switch reminding anyone it’s there if you need it.
Bluewater 9800-011-11 battery switch is a make-before-break switch, so it is safe to turn the switch from ON, to COMBINE while your engine is running.
This switch works great with an ACR setup – where an automatic relay is used to charge your house battery only when the starting battery has been topped off.

Works great and its flush mount looks.

Ease of installation. The original switch broke after 8 months. The new one turns smoother and doesn’t catch.
Customer service was very helpful.
