ABSTRACT:
A medical apparatus having a variety of electrically actuatable elements includes actuation arrangement for assisting the selection of functions of the electrically actuatable elements. The actuation arrangement includes a single actuation device, preferably a foot switch, that can be brought from an initial position into two working positions. By actuating the actuation device into one of the two working positions, function display elements provided with symbol identifiers and optical signal generators are driven in succession and are displayed on a visual field. A control arrangement processes the control signals from the signal generators, such that the optical signal generators of the function display elements are successively driven in accordance with the selected actuation direction until a desired function display element is reached. The appertaining operator elements are thereby switched in a preparatory manner. By subsequent actuation of the actuation device into the other working position, the appertaining operator element is activated.
