Abstract
A hand-held power tool, in particular a rotary hammer, is indicated that includes a machine housing (10) with a tool fitting (12) integrated therein, the tool fitting (12) being rotatably drivable in a first mode and being non-rotatably fixable on the machine housing (10) in a second mode, and that includes a duty-type switch (20) with a coupling element (21) capable of being displaced to activate the modes, and an actuating element (22) that induces its displacement. To prevent maloperation and resultant damage to the machine when the operator switches between modes, the actuating element is designed as an electrical actuator (23), preferably as an electromagnet (25) controlled by an electronic control unit (24) (FIG. 1).
