Abstract
A panel for an elevator installation has a predetermined number of floor buttons for generating hall calls or car call commands wherein a single floor button or a floor button combination is provided for each floor. The panel can be converted by a converter button or a sensor so that all floors are also selectable by a decade keyboard formed by a portion of all the floor buttons. All floors are thus selectable comfortably and without restriction even by handicapped persons.
