Seaflo Circuit Battery Disconnect Switch
Switches a single battery to a single load group.
Tin-plated copper studs for maximum conductivity and corrosion resistance. Studs accept 3/8" (M10) ring terminals.
One-piece terminal stud design never loosens over time. Isolating cover with three snap-off side pieces protects rear contacts and allows wire access in any direction.
