@janpom Could implement a very small and simple compliant mechanisim that would help locking the key in whichever position its in, so it requires a greater force to push or pull the key. It would need probably 2 or 3 iterations to get it just right but to mee it looks like a good solution.
It already requires quite a bit of force, especially with a new XT90 male connector. The one I have is already pretty worn out and there’s less friction. I had a new one for mocking things up and that one worked really well. Still, even with the worn out one, if you hold the board in the upright position, the gravity on the loop key itself is not enough to close the circuit.
Your diagram is giving me other ideas though. I could add a simple locking mechanism that goes is from the side. Something like this:
Maybe that’s too complicated though. I could just as well make a simple part that I slide on the handle and that will then sit between the handle and the deck and thus prevent the handle from being pushed in.
I feel that your loop key it’s pretty unique and that it deserves a cool and elegant way to solve the locking problem, even though that part would be very useful so you could make it and then iterate your design for future updates
Pick your toy of choice.
I would be interested to see the big one dead center of the pic, holding against a bearing ball half burrowed into the 3dprint. Also a bit of grease
The correct name for these is flat leaf springs. Unfortunately it shares the name with the leaf springs suspensions on cars which makes searching on cancer search engines like amazon and ebay impossible.
