Just thought I'd throw this out there.
In my FB feed there was an ad for this company and within a couple of clicks got to their page of battery disconnect switches. While expensive, it seems like a lot of these are much better than the bosch/hella stuff most of us use.
I went through one of the standard red handle switches about every 3-5 years. Eventually the combination of contact buildup and vibration causes them to start bouncing and if you have an electronic dash that's pretty much the kiss of death. The car will usually keep running but the dash will either lock up or re-boot all the time. Last time this happened to me it was a very expensive flaming river switch that lasted something like 4 weekends. I had to swipe the original Lucas unit off of my 1972 FSV and it's been working fine at 47 years old!
However, if you don't have access to an item made when people still knew how to make stuff last, you might look at the items here. What impressed me was that they actually had the specs for shock and vibe. Haven't been able to find that on any of our usual products.
