A foot-actuated control arrangement, in particular for dental apparatuses, including an actuating element acting on a switch or control element, and which is equipped with a treadle. The actuating element is displaceable towards both sides from an initial position in one plane, is displaceable along a pivoted path about a stationary position, and can be restrained through at least one setting or control element in the mentioned initial position along the pivoted path and, subsequent to a displacement from this position, can be automatically returned thereto.

Foot-actuated control arrangment particularly for dental arrangment

A dental treatment apparatus having a plurality of dental instruments releasably retained in an instrument-holding device. A control and display arrangement controls the operation of an instrument upon extraction from the holding device, and displays the magnitude of an operating parameter of the instrument on a display device. A control data store is arranged to store pre-determined fixed control data values for the operating parameters of the instruments. To enable the user to alter the predetermined fixed values, a forward-backward counter is connected to the data store which can also store the altered values. A data converter is connected to the counter and to the display device for converting the instantaneous value stored in the data store to a corresponding service datum instantaneous value to be displayed by the display device.
