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