A switch () for a hand-held power tool () or as a component of a hand-held power tool (), which has an electric drive motor () that can be switched by the switch (). The switch () has a switch housing () with a switch chamber () in which a switch actuator () that can be moved between at least two switch positions (ML, MR) is arranged in order to actuate an electric switch element, said switch actuator being kinetically coupled, by means of a transmission element (), to a switch () actuation element (), which is arranged outside the switch housing () and can be moved between at least two actuation positions (R, L), wherein the transmission element () passes through a through-opening () on a wall of the switch housing () such that the switch actuator () can be moved by moving the actuation element () in order to actuate the switch element (). A rotary bearing () is arranged in the through-opening (), the transmission element () being rotatably mounted on the rotary bearing about a rotational axis (D).

Switch for a hand-held power tool

A manual machine tool having a drive motor, a gearbox arranged on a gearbox housing and a tool holder, wherein a motor drive of the drive motor with a gearbox drive of the gearbox and a gearbox output of the drive that is rotatable about an axis of rotation are coupled to the tool holder in a manner which permits rotation, wherein the gearbox can be switched between at least two switch positions in which the speed ratios between the gearbox drive and the gearbox output are different from one another, wherein the gearbox comprises a first wheel arrangement and at least a second wheel arrangement, each of which have at least one gear wheel and a switching gear element, wherein in both gear wheel arrangements the at least one gear wheel on the switching gear element and/or the switching gear element on at least one gear wheel can roll and the respective switching gear element is mounted in a locally adjustable manner to adjust the switch settings of the gearbox on the gearbox holding structure between the at least two setting positions and/or can be adjusted relative to the gearbox holding structure (A) between an immobile position and a mobile position.

Hand-held power tool

A manual machine tool having a drive motor, a gearbox and a tool holder, wherein a motor output of the drive motor having a gearbox drive of the gearbox and a gearbox output of the gearbox are coupled to the tool holder in a manner which permits rotation, wherein the manual machine tool has an actuating device to adjust the gearbox between its switch positions, wherein the actuating device has an actuating part which is movably mounted between actuating positions relative to a machine housing of the manual machine tool and which can be manually actuated, which actuating part is coupled to the at least one switching gear element to set the switch positions. The actuating device has a locking arrangement with locking indentations arranged on a locking structure to lock the actuating part in the actuating positions, which locking indentations are assigned to actuating positions of the actuating part, and with a locking part to engage in the locking indentations.

A manual machine tool having a drive motor, a gearbox and a tool holder, wherein a motor drive of the drive motor with a gearbox drive of the gearbox and a gearbox of the drive that is rotatable about an axis of rotation are coupled to the tool holder in a manner which permits rotation, wherein the gearbox has a first switching gear element and a second switching gear element, which can be adjusted in a linear manner by means of an actuating device in each case between a first setting position and a second setting position relative to the gearbox housing, wherein the actuating device is coupled to the switching gear elements and has an actuating part which is pivotably mounted relative to a machine housing of the manual machine tool about an actuating pivot axis and can be actuated manually by an operator of the manual machine tool, wherein the first switching gear element can be adjusted in a linear manner along its setting axis by means of a pivot movement of the actuating part about the actuating pivot axis using a deflecting gear.
