R230 mirror adjustment switch

[cmc]

Hi All,
The mirror adjustment switch on my SL55 has popped out but it seems that there is a circular piece that actually engages the directional controls which is missing. Does anyone know if this can be bought on its own as the unit is actually still working.

thanks in advance

Hi good people…
Anybody have any responses to the above ?
Feels like the part should be replaceable but can’t find any reference for it anywhere.
