The real innovation with these switches isn't the butterfly mechanism or the itty-bitty steel spring. It's the fact that the switch can be placed on a PCB just like any SMD component by a pick and place machine. It doesn't mention anything about it but I believe the plastic bits get added later--after soldering. Based on my understanding of the mechanism it will likely suffer the same fate as Apple's butterfly switches in that dust and hair will completely wreck it and there's no good way to clean that stuff out. The world needs to move to contactless switches so they can be easily cleaned like this: https://gfycat.com/unconsciousvigilantkinglet https://gfycat.com/unconsciousvigilantkinglet (That's one half of the top plate from my analog keyboard with 3D printed magnetic separation switches)
