Oh, now Leobog has magnetic switches too! They have a weird square-ish stem and a HaiMu-style leaf spring on the bottom. They bottom out on the magnet so they definitely aren't silent, but to be fair they don't advertise them as silent either, maybe there will be a version with a shorter magnet and they're just going to reuse the molds.  Bottom Out Force: 49g Bottom Out: 3.4mm
