Abstract
A foot-operated starter or controller for a dental treatment apparatus possessing a patient's or dental chair and a plurality of treating instruments which are arranged in separate repositories, including actuating elements through the actuation of which there can be initiated or varied different functions of the applicable treatment location. The actuating elements are interconnected with a switching or junction circuit arrangement, which is connected in such a manner with display devices indicative of the removal of the treating instruments from their repositories, such that merely upon withdrawal of at least one treating instrument from its repository, the actuating elements serve for the regulation of the adjusted setting of the applicable treating instrument, whereas at the presence of the collective treating instruments in their repositories they serve for the setting of the adjusted positions of the dental chair.
