Blue Sea Systems Battery Switches - HD Series - Single Circuit
These Blue Sea Systems heavy-duty single circuit battery switches offer 600 amps for large diesel engines. These switches switch a single battery to a single load group and feature tin-plated copper studs for maximum conductivity and corrosion resistance. Accepts up to 4/0 AWG battery cables. The studs accept 1/2" (M12) ring terminals and have a 7/8" stud length (22 mm) that can accept multiple cable terminals. 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. Tactile indicator conveys knob position by feel. 5442 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.
