Abstract: A hand-held power tool is provided which includes a clutch housing of a torque clutch, and a planetary gear, situated in a gear housing, for transmitting a torque which is generated by a drive motor to a drive shaft. The clutch housing cooperates with the planetary gear via a pressure plate. The pressure plate is displaced in the axial direction in order to disengage the torque clutch. The axial relative motion of the pressure plate causes an axial relative motion between a switching element and an associated optical sensor, via which the drive motor may be switched off.
