Hi!
Disassamble it, clean the kontakt surface with precision kontakt spray, or IPA. For the arretation plastic button I offer PTFE (Teflon) spray..
Should be better, when not buy a new one.

Hi,
Thanks Joe for your answer.
Yes I do it but the problem that I lose the right position of 10 teeths of the rotary position. Have you a photo which show their right emplacement.
Regards.
