Bc2000 (for the BCF2000 & BCR2000)

Hello

unfortunately yesterday my bcr2000 fell against a rack and
i have now the top right 3 encoders broken

Anybody knows the exact type , so that i can buy
and fix them.

I guess there are 2 types with click (the top row)
and without click (the lower 3 rows)

Tnx in advance
Andrea
