If you want, you can hide as many kill switches as you want, anywhere on the bike, you just wire them in series. I have secondary hidden kill switches on my Sportster and on my Bratstyle XS650. Neither of these bikes has a key switch, just an on/off toggle ignition switch, that is why I have the secondary kill switches, to thwart theft. For a hidden kill switch you can use almost any toggle switch, I have used mini and micro toggles. And yes, they both have primary kill switches on the bars, next to the grips.
