Different colors for different functions.

Color-coded switches don't cut it from a human
factors standpoint. I need something that *feels*
different to a gloved hand. Turning the fuel pump
switch 90 deg will do it, as would a bigger bat. If
I can see the color, I can see whether or not I've got
the right switch, regardless of the color.

Obviously, the interim workaround is to visually verify
any switch before throwing it. Not a big deal in the
short term.
