Trying to add a lever to the hook for a couple reasons.
The first is that using the switch's built-in one is a bit twitchy.
The second is that I don't like having the unprotected switch exposed, including the electrical connections. It's not really a safety thing, but if it's every used outside, they'll probably corrode, etc.
The third is that it just looks better :)
I'm not sure how it's going to turn out, but that's the fun of rapid prototyping. You can try something that you think *might* work, run off some parts and see first-hand what you did wrong. For me this is a huge help because it's easier to understand how things fit together with my hands than on-screen, but it would be impractical to do it this way if I was spending hours hand-fabricating parts.
