These single circuit Blue Sea Systems battery switches offer 300 amps for outboards and small gasoline or 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. 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.
