So I was playing around with a Cherry MX Brown model switch I got for free along with my Ducky keyboard. I finally discovered how to open the model switch and started to fiddle around with the internals. But after I reassemble the switch, the tactile bump dissapeared. As a result, the switch is now a Cherry MX Red with a brown stem.
I'm pretty sure everything is still inside the switch. Anyone got any idea what could cause the switch to turn into another kind?
