A hand-held electric power tool () includes a switching gear unit () which has at least two switching stages, including an impact mechanism () which can be switched on, and a mode switch () with which the switching gear unit () can be switched back and forth between the switching stages. The impact mechanism () can be switched on and off, and the mode switch () is movement-coupled with a gear unit switching mechanism () of the switching gear unit () and with an impact mechanism switching mechanism () of the impact mechanism (). The impact mechanism switching mechanism () has a swiveling mechanism which can be swiveled by the mode switch () between an active position, in which the impact mechanism () can be activated, and a passive position in which the impact mechanism () is deactivated.
