Ive had a Zibal 60 pulled apart like a scene out of a CSI episode and we can conclude that it seems to be the switch itself which is made by Cherry and not anything on the keyboard. We have reds, blues and browns too and they ping the same way. Sorry if this does not help but at least i can confirm its nothing with the Zibal build. /richard
Both aspects counts.
Some switches are pinging, I had two in my xarmor, and it's clearly a Cherry assembly issue.
But
If the switches and the leds are pushed tightly during the soldering process the ping become almost inaudible, because there is some clearance between the pcb and the switches soldered with the industrial process.
I already published here the audio samples of a pinging switch (the same switch) , before and after the resoldering process.

Later I've also found a brand new, unmounted pinging switch.
I opened it to understand what's going on.
Well I just reassembled it, w/o any other additional action, and the ping was completely gone.
I presume that some switch's cursors, during the assembly process, are assembled with a rotational movement that charge the coiled spring with a torsional force.
Once disassembled that force is discharged and the switch start with the expected behavior.
I hope this helps.
