Much harder than I had to with the Cherry switches. I've been experimenting with applying pressure outside of the PCB and cannot replicate the issue. It's only when the switches are inserted.
However, after some experimentation last night, I did realize this is indeed an individual switch issue. The problem is that they work perfectly fine until they're fully inserted into the PCB. Then they got choked. I've identified a couple of problematic switches and re-assembled them but the issue is still there.
I'll try and remember to share some media later. I like your idea of installing without the top housing. I'll try that later. Thanks for commenting.
