thanks for the pics. The spring looks to be one of these new “preloaded” springs that reportedly reduce the difference in spring weight between actuation and bottoming out. There are a few new switches coming out lately that have these long springs. I’m not sure about the physics behind it. Seems like it would just make for a slightly heavier spring overall. How do they feel to you?
How do they sound? Are the top housings tight or do they need films?
