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.

A multi-mode drill includes a housing, a motor and a transmission mechanism, wherein the motor and the transmission mechanism are received in the housing. The transmission mechanism has a gear reduction component and a main shaft, wherein the gear reduction component is driven by the motor, and the main shaft is connected with the gear reduction component and driven by the gear reduction component to rotate. The multi-mode drill further includes a mode switching mechanism for causing the transmission mechanism to operate in different modes. The mode switching mechanism includes an operation member and an actuator. The actuator is actuated by the operation member and engages with the transmission mechanism. At least an elastic energy storage member is arranged between the operation member and the actuator.

The disclosure relates to a method for operating a handheld power tool having an electric motor, the method comprising: S1 providing at least one model signal waveform that is associated with a work progress of the handheld power tool; S2 determining a signal of an operating variable of the electric motor; S3 comparing the signal of the operating variable with the model signal waveform and determining a conformity evaluation on the basis thereof; S4 identifying the work progress at least partially using the conformity evaluation; S5 executing a first routine of the handheld power tool at least partially on the basis of the work progress identified in method step S4. The disclosure also relates to a handheld power tool, in particular an impact driver, comprising an electric motor and a control unit, wherein the control unit is designed to carry out a method according to the disclosure.

A rotary power tool includes a housing having a motor housing portion and a handle portion extending therefrom. An electric motor is positioned within the motor housing portion. The rotary power tool further includes a trigger switch configured to activate and deactivate the motor. The rotary power tool further includes a non-contact speed selector switch that is separate from the trigger switch and configured to adjust a rotational speed of the motor. The non-contact speed selector switch is positioned in a foot of the handle portion opposite the motor housing portion.

An electric machine tool includes a first actuating device and a second actuating device. The second actuating device is arranged at a distance from the first actuating device. The first actuating device is mechanically connected to the second actuating device by a switching connector which is configured to be loaded in tension only.

A power tool includes a housing, a motor disposed in the housing, a motor controller disposed in the housing and electrically coupled to the motor, and a transmission disposed in the housing and coupled to the motor. A tool bit holder is rotatably driven by the motor via the transmission and receives a tool bit for rotatably driving threaded fasteners. A power switch and an electronic model select switch are actuatable from outside the housing and are coupled to the motor controller. The power switch controls power delivery to the motor. The electronic mode select switch is configured to select between at least a first mode of operation in which power delivery to the motor is controlled by actuation of the power switch and an electronic lock on mode in which continuous power is delivered to the motor upon a single actuation and release of the power switch.

A hand-held power tool, including: a drive circuit for providing an adjustment signal as a function of actuation of a button, a control apparatus for adjusting a drive current for an electric motor of the hand-held power tool as a function of the adjustment signal, wherein the control apparatus is connected to an electrical energy source for operating the hand-held power tool via a first electrical line arrangement, the drive circuit is connected to the control apparatus via a second electrical line arrangement, a drive current line carrying the drive current for the electric motor is routed via an interruption switch, coupled to the button, for interrupting the drive current, and wherein an interference-suppression capacitor is connected to the drive power line via a first node and to the second electrical line arrangement via a second node.

A portable machine tool switching unit includes a turning knob unit, which has a coupling unit that can be rotatably driven for coupling to at least one switching element, and further includes at least one energy storage element provided for storing switching energy in the case of a preselection. The energy storage element is integrated in the turning knob unit.

A handheld power tool has a switchable gear component actuatable by a selector switch. The gear component moves from a first operating position into a second operating position. The selector switch has a first switching position associated with the first operating position and a second switching position associated with the second operating position, and movable so that intermediate positions are assumed. A traveling coupling between the selector switch and the gear component has a spring exerting force onto the gear component in the first direction. A locking bolt is coupled to the selector switch in a positively driven manner. In the intermediate positions, the locking bolt is moved into a blocking bolt position blocking movement of the gear component out of the first operating position into the second operating position. When the selector switch is in the second switching position, the locking bolt is in a releasing bolt position.

A power tool includes a housing having a motor housing portion and a handle portion extending therefrom. An electric motor is positioned within the motor housing portion. The power tool also includes trigger switch configured to activate and deactivate the motor. The power tool further includes a non-contact mode selector switch that is separate from the trigger switch and configured to adjust an operational mode of the tool. The non-contact mode selector switch is positioned in a foot of the handle portion opposite the motor housing portion.
