A dust extraction device for a hand-held power tool includes a housing, a mechanical interface for releasably connecting the dust extraction device to the hand-held power tool, a dust-collecting chamber which is connected to a filter unit, and a filter-cleaning unit. The filter-cleaning unit has an impact element which is mounted moveably in and/or on the housing of the dust extraction device. The impact element is designed to act upon the filter unit directly with an impact-like force.

A switching device for a portable power tool includes at least one operating mode selection unit, which has at least one movably mounted operating element for selecting an operating mode of the portable power tool. The switching device also has at least one locking unit for locking the operating element in at least one movement position of the operating element. The locking unit has at least one movably mounted locking element which, depending on a locking position of the locking element, triggers an electric and/or electronic signal for switching an operating mode of the portable power tool.
