A device adapted for special use in a reset timer/counter unit to return various digital counting subwheels to their reset condition after a timing or counting cycle. The device includes a first ring formed from a permanently magnetizable material having a generally circular first pole surface with a set of opposite polarity magnetic poles arranged in a selected pole pattern on the first pole surface and means for securing the first ring onto one of the subwheels or other device to be returned to a selected position. The second ring formed from a permanently magnetizable material is provided with a generally circular second pole surface generally facing the first pole surface and having opposite polarity magnetic poles arranged in a pole pattern matching the selected pattern of the first surface with poles of the first surface generally facing opposite polarity poles of the second surface when the members to be controlled are in a selected angular returned, or known, position.
