How many garbage disposal accidents per year?

17 in one area possibly, but there are thousands of these accidents annually in the US alone. Unfortunately, the majority of those involved children. Blenders are also a common cause for related "in the home" injuries.

Some type of switch identifier, like "Which Switch?", would not only help minimize garbage disposal accidents, it would save a tremendous amount of energy from the accidental turn-ons (and subsequent turn-offs) that occur when people fumble through several light switches trying to find the correct one.
