It is designed to be nothing more than a design example. Sorry about that.
I used nothing but
COLE HERSEE
Brand switches. Made in USA. They will support a 700 amp intermittent load and a 200+ alternator charging load.
In an emergency serious users do not fiddle around wondering where OFF is. Multiple circuits on a fishing trawler. Someone twists every switch to the left. There's no braille and no guesswork.
I have gone through* an inventory of perhaps 70-100 of these switches. Their reliability is flawless even around the seashore.
Be certain to get the LONG THREADED NECK model. This allows for mounting in laminated, dual layers and carpeted.
I would pit a Cole Hersee lever on-off switch against the heaviest duty Blue Seas dial switch, any day of the week. the CH lever switch is some beast. The contacts are silver CLAD. And there is no way to escape the added expense.
* In house and over-the-counter sales.
