Abstract

The invention relates to a switch for a hand-held screwdriver or hand-held drill which is driven by an electric motor, whose rotation direction can be reversed and whose rotation speed can be adjusted. A potentiometer (4, 5) whose voltage pick-off (tap) determines the rotation speed of the drill is adjusted by means of a slide which can be displaced against spring force by pressure on a button. Tilting the slide allows the polarity of the picked-off voltage and, via this, the rotation direction of the motor to be determined. <IMAGE>
