  • Patent number: 11858102
    Abstract: A hand-held power tool having a motor-driven impact mechanism and monostable operating button. A locking switch for the monostable operating button has a sliding direction, an actuating knob, a catch and a sliding block, wherein the actuating knob is able to be moved by the user in the sliding direction from a releasing position to a locking position. The catch is pivotable in a pivoting direction perpendicular to the switching direction between a first position and a second position. The catch is disengaged from the operating button 6 in the first position and the catch engages in the operating button in the second position, arresting the operating button in the pressed position. The catch has, on a side facing in the pivoting direction, a slotted-guide face that is inclined with respect to the sliding direction. The sliding block bears on the slotted-guide face.
