By the looks of it's just a regular tactile switch, (6x6x5) https://youtu.be/YZ6Kqpd5028?si=3ipio1UxsUY6agB9&t=459 @7min mark, not 100% sure but... about 95%. :)
You can buy tac switches in any electronics store and they usually cost about 0.10 cents a piece, some websites sell them for insane prices with the NI name attached... If you don't have experience soldering I don't advise you to do this yourself, if you mess up the PCB then it's bye-bye controller or expensive repair.
Either send it to NI to repair which will cost you a pretty penny if it's out of warranty, or just go to your local electronics repair store..
