Whats everyone using for a battery disconnect switch on their mopar new and old?

I have a performance plus battery disconnect switch thats been on the car for 7-8 years, i recently noticed that a few times i go to switch it on and the car seems like its getting intermittent power. Turn the switch off then back on and its fine. Well yesterday pulling in the car show it died, of course lol of all the places, turned the ignition off and on and nothing, did it again and i could see the shift light briefly flash but didnt not stay on for the 2-3 seconds like its suppose to when the ignition is first turned on. Got out and turned the disconnect switch off then back on, she fired right up. So when i got back home i took the switch out, the off and on position still feels solid but the contacts inside must either be dirty or worn, i was looking at the switch on the company's website and its only rated for 450 amps momentary, i know the battery is way hotter than that, so im going to replace it with either a 1000 amp or a 2500 amp momentary rated switch. But theres so many brands, just curious as to what everyone was having luck with. Im looking for a manual rotating switch. I was looking at flaming rivers “big switch” but i contacted them for the switch dimensions as i only have a limited space where the bracket is. Thanks for any advice!
