Blue Sea Systems Battery Switches - M-Series - Dual Circuit Plus

These Blue Sea Systems dual circuit plus battery switches offer 300 amps for outboards and small gasoline or diesel engines. These switches simultaneously switch two isolated battery banks or combines battery banks to all loads. They CANNOT be used to switch positive and negative conductors because of the combine feature. They 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. Blue Sea Systems one-piece terminal stud design never loosens over time. One-piece stainless flange nuts ensure safe and secure connections. Isolating cover with three snap-in side pieces protects rear contacts and allows easy wire access in any direction. Case design allows surface, rear or front panel mounting options.
