Boat wiring advice

[MSM1970]

Does the Perko switch have places where one can connect multiple cables to it?

Yes the perko dial type switch works, good, I have one, you can change it form 1 to all batterys, I put my ground on the switch(fiber glass boat) when I plugg it in I will turn it to all and all 3 batterys charge, long storage turn it off, my batterys where still charged this spring,
