Abstract: A hand-held power tool includes: a shiftable transmission for driving a drive shaft, which transmission is situated in a gear housing and is shiftable at least between a first gear and a second gear via a shifting member; and a pivotably supported actuating element, which is configured as a bistable spring element and situated, at least in sections, in the area between the shifting member and the gear housing, is associated with the shifting member. The bistable spring element is actuatable for the gear shifting, and assumes a stable shift position in at least one shift position of the shifting member associated with the first or second gear, and assumes an unstable position in an intermediate position of the shifting member which is situated between shift positions of the shifting member associated with the first and second gears.

Abstract: A hand-held power tool which includes a shiftable transmission that is shiftable at least between a first gear and a second gear via a shifting member, in which the shifting member is coupled to a spring element, which for the gear shifting is indirectly or directly actuatable at least via a first and a second shifting element. A coupling element which is coupleable to the spring element is associated with the first shifting element, and the coupling element is configured for allowing gear shifting by actuating the first shifting element only for the case that the second shifting element is in a predefined gear shift position.
