Blue Sea 9001E E-Series Selector Battery Switch

These four position Blue Sea Systems battery switches offer 350 amps for inboard gasoline or diesel engines. These switches switch isolated battery banks to all loads or combines battery banks to all loads and feature tin-plated copper studs for maximum conductivity and corrosion resistance. The studs accept 3/8″ M10 ring terminals and have a 7/8″ stud length 22 mm that can accept multiple cable terminals. Accepts up to 4/0 AWG battery cables. Blue Sea Systems one-piece terminal stud design never loosens over time. One-piece stainless flange nuts ensure safe and secure connections. Fits most Perko and Guest low amperage battery switch hole patterns. Case design allows surface or rear panel mounting options. Part number 5437 includes Alternator Field Disconnect AFD which protects the diodes in the alternator in the event of the switch being switched to the OFF position while the engine is running. If the AFD is not used to protect the alternator an LED can be connected to the AFD terminals to indicate when the battery switch is in any position but OFF.
