Yes, they’re the linear Kailh Choc V2 Red switches.
I just want to warn you, in case you don’t already know; the UHK60 doesn’t use the Choc switches at all, and the upcoming UHK80, only uses a total of four of the Chocs (on the very bottom row of the thumb clusters - Fn2/Space/Mod/Fn2).
All the others are standard MX style switches. The Chocs are NOT compatible with the MX hotswap sockets.
EDIT:
Also, the MX style sockets are NOT compatible with any low profile switches. The only “low-ish” switches known to work are these “medium” profile Tecsee switches:
Here’s another thread showing off the Tecsee mediums:
