That kind of switch might handle an amp or two. Anywhere near 100A would melt the wiring to the switch, the switch itself, and the housing on the handlebars, and all the other wiring near it, shorting all the differnet voltages together, damaging all the affected components and probably starting a fire.Has anyone used those standard kill switches found on traditional (non-e) bikes? (my Suzuki had it too, of course)
And for a setup as high as 100A - Which switch holds up? Anyone has experience to share?

You need a large high current switch to reliably disconnect that kind of current at the voltages you're dealing with on vehicles like this. A circuit breaker is a good way to do it because they're designed to break current under load, and not all switches are. They usually have springloaded contacts to help this happen very fast, where switches usually don't, so the switch may have to be larger to handle the slower turn off as you manually move the swtich toggle, wiper, etc. without too much damage to the contacts.
