Sea-Dog 32V 300A Mini Battery Switch Key

This Sea-Dog Mini Battery Switch, model 422730-1, features a removable knob for extra security. Twist the cap to the OUT position and pull to remove it, taking the key with it when leaving the boat.

Its mini footprint makes it ideal for close quarters where a full-size selector switch wouldn't fit. It's rated at 300A continuous and 1,000A cranking amps, plenty of capacity for a single-battery setup.

Installation is straightforward: drill a 2-1/16-inch hole, insert the socket body, tighten the locking nut, and connect the wires. The switch offers 3 switch positions for flexible operation. See what else we carry in battery management systems.
