I didn’t know there was an issue with the switches. I have two SC52s; one with an old switch and the other with a new one. The old switch makes an audible *click* when pressed. The new switch is silent. Other than that, there seems to be no other difference.
When I talked to the Zebra rep a few months back, he said they were getting ready to move production to the U.S., so maybe that has something to do with it?
