Roland CR-78 Switch Replacement

I’m chasing these switches: https://syntaur.com/Items.php?Item=6603 (currently out of stock)

These switches are interlocked, but does anyone know if they are available to buy individually anywhere?

The issue im having is that many switches on my Roland CR-78 are sticky and need to be manually pulled out to disable that particular pattern - external cleaning has not helped and seems they’re not designed to be opened up.

Any thoughts?
