The 250 Amp battery master switch is mounted in a recessed box with a waterproof cover that's sealed with an o-ring. The box itself is sealed with a gasket, to prevent water from entering the console.
This is idea for open boats, where the battery master switch can be mounted in a console or locker cover and easily accessed, without having to lift a seat or move things inside a locker.
The battery switch is kept dry and the cover keeps the boat looking tidy and the switch away from being accidentally knocked or able to snag a rope and get switched off.
The battery switch has a removable key for added security and is provided with a rubber cap for when the key has been taken out.
