While they have made their own switches in the past, these look exactly like premade switches. I don't feel that the model numbers serve to help identify the actual switch.

I can't tell between Choc V2s, or Cherry MX Low-Profile, but this review shows the switches in better (read: any) detail than Logitech's page: https://www.tomshardware.com/reviews/logitech-mx-mechanical-...

'MX' made me think it might have been Cherry, but the review says Chocs, so that's what I'll believe. MX is probably included to signal 'MX compatible stem'.
