1. A hand-held tool machine, comprising:
a switchable mechanism having at least a first operating position and a second operating position; an adjustable switching element; a coupling element implemented as a bistable coupling spring; and an operating element coupled to the adjustable switching element via the coupling element, wherein the adjustable switching element is configured to act on at least one mechanical component of the switchable mechanism such that the switchable mechanism is adjusted between the first operating position and the second operating position in response to a positioning movement of the operating element; wherein the bistable coupling spring is configured to assume a stable position in a first switching position and a second switching position of the operating element, and assume an unstable position in an intermediate position between the first and second switching positions of the operating element, wherein the bistable coupling spring is implemented as a spring washer and is positioned in the hand-held tool machine under prestressing, wherein elements, which at least one of tilt and pivot, are formed integrally with the spring washer to define an axis running substantially perpendicular to a longitudinal axis of the hand-held tool machine, and wherein the spring washer assumes a non-planar form under pre-stressing in the first and second switching position. |
