The invention relates to a control unit of a medical apparatus with a front panel (1) with setting knobs (5). In order to transfer a turning setting movement through the front panel (1), a feed-through sleeve (6) is rotatably arranged in the front panel (1) and a knob core (10) is movably arranged in the feed-through sleeve (6). On the control side of the front panel (1), the feed-through sleeve (6) and the knob core (10) are enclosed by a handling element (16), which through application of pressure can move the knob core (10) in the feed-through sleeve (6), whereby the knob core (10) on the back side of the front panel (1) moves a springing locking washer (11) from a locking position to an unlocked position so that a turning of the handling element (16) also will move the feed-through sleeve (6). In order to improve the sealing at the feed-through, the front panel (1) is provided with a protection plate (4) which is beaded (21) outwards at the feed-through sleeve (6), whereby the handling element (16) tightly encloses the beaded (21) part. <IMAGE> |
