Battery disconnect switch

how is your boat wired? do you have a pos and neg that feeds a fuse panel and all accessories run from that? if so just put in a simple switch before the panel on the positive wire. it would have to be a big enough switch to carry all the amps that all of your accessories use...like maybe a 40A on/off switch would work.

This "simple switch" is what I'm looking for. Finding which switch to use that can handle the current and mount on my console is the problem. Ezacdc only shows rectangular mounted switches and I have no way to cut the hole to mount such a switch.

A rectangular switch would work except I have no way to cut the rectangular hole in my console. There are two of the switches on my old boat that have worked perfectly for 30 years. I'd only have to drill one hole to mount it. It would have to have at least a 20 amp rating. I've found a lot of reset switches except they only shut off when tripped. Or there are a lot of momentary contact switches. It doesn't seem like this should be difficult to find, but a switch with a high enough rating limits the choices.

These are the switches on my 30 year old Ranger.


I have found something that will work, but at $75 it seems pretty pricey.

Does this link work for you?

https://www.mouser.com/Electromechanical/Switches/Pushbutton-Switches/_/N-5g30Z1yzvvqx?P=1z0x8h3&Ns=Pricing|0

20 amp push button, in stock, sorted by price. Read the datasheets to ensure it will work for you. Shipping should be $5.

Also, it is pretty easy to make a single square hole with a drill bit, and a file.

Edit: I should note that if a switch on that page is listed as something like (ON)-OFF, it is a momentary switch, and wouldn't work for you. You want an ON-OFF, not an (ON)-OFF or an ON-(OFF).
