10AX switch + matt white key SIMON 8200201-090
The Simon 82 Concept series of mechanisms allows the mechanism and the cover to be purchased together. It is important to note that, in the same way, the mechanism and the cover can be purchased separately.
If you have the Simon 31, 75, 82 or 88 series of mechanisms, it is not necessary to purchase the mechanism, so you will only have to add the key.
