FIELD: instrument making.SUBSTANCE: present invention relates to control panels for measuring instruments. Proposed control panel (1) includes housing with at least one viewing and control window and at least one optical key (2) to be actuated by a finger through said window and having a transmitting element (3) and receiving element (4). Additionally there is at least one result processing unit for detecting actuation of optical key (2) and a mechanical keys (6), and control panel (1) in addition to optical key (2) configured for actuation by a finger has at least one corresponding finger-actuated mechanical key (6). Result processing unit deactivates optical key (2), as soon as mechanical key (6) is actuated, in particular in presence of multiple optical keys (2) configured for actuation by a finger and corresponding mechanical keys (6) configured for actuation by a finger, result processing unit deactivates all optical keys (2), if mechanical key is actuated.EFFECT: proposed panel provides possibility of reliable and fast control, including for open panel.13 cl, 2 dwg |
