Shaved Ice, Not Shaved Fingers

Rival sells a shaved ice machine that spins the ice around, pushing the ice over a blade that shaves it into snow cone “snow.” Rival is very interested in NOT shaving any fingers.

They have designed the “on” switch into the lid. You press on the lid to activate the machine. When you stop pressing the lid the machine stops rapidly. The tabs shown on the lid in the picture (below right) press switches beneath the small holes (one shown with the larger arrow).  You physically cannot have your fingers in the mechanism and turn it on at the same time (unless you are a masochist with a pocket knife or small screwdriver).
