Yeah, I'd say you could orient a little 2-way on-off toggle killswitch and set it up side ways so your downstrokes don't shut you off.
Or I like the semi cosmetic push pull volume pot. Just hook it up so out is off, and in is on. No way to accidentally kill your signal.
For me, on my M-II custom, I keep banging the sinclair tremolo arm on the volume pot when I'm doing my whammy stunts.. Not the best positioning.
