Abstract

The dentistry equipment comprises a control for an instrument and particularly a drill, with rheostat and a reversing switch both controllable by hand. The allow an electrical connection to be made between the slide of the hand-controlled rheostat or that of a foot-controlled one and a drive to the instrument. The reversing switch (28) and the hand-controlled rheostat (14) have a common control, and the switch is mounted at the start of the rheostat control area or that of the control (12).
