Hey, gok. Thanks for putting up the model showing the mounting method. So if I'm looking at this correctly, the thing that's usually the mounting plate won't actually be attached to the chassis in any way. It will be held by the switches, which will be soldered to the PCB (with a foam layer in between) and the PCB will be isolation mounted with protruding "tabs" connected by leaf springs? Is this correct?
If so, are there any worries about the durability of this kind of setup? The whole weight of the assembly and the force from the key press will be distributed to the chassis through thin leafsprings made out of fiberglass (or any other PCB substrate).
I've never seen this kind of mount anywhere else. What sort of feel is it supposed to provide? How much give do the leaf springs have? Are they going to be hard-limited when pressed down by some sort of bottom element? What sort of switches would best benefit from this kind of setup?
Sorry for bombarding you with questions, but this is very intriguing.
