Take control of your onboard power with this robust medium‑duty battery selector switch featuring an Alternator Field Disconnect (AFD) for added protection. Designed for marine electrical systems, this switch lets you safely select between two battery banks, combine them in an emergency, or isolate power for accessories or charging. The AFD protects non‑unitized alternators if the switch is accidentally turned “OFF” while the engine is running
