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.

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 impact tool includes a motor, a driving mechanism, and a vibration sensor. The driving mechanism is configured to perform a hammering operation of linearly driving a tool accessory along an impact-axis by power of the motor. The impact-axis extends in a front-rear direction of the impact tool. The vibration sensor is configured to detect vibrations. The vibration sensor is disposed such that the vibration sensor is capable of detecting vibrations of a first frequency among vibrations caused in the impact tool, and such that transmission of vibrations of a second frequency to the vibration sensor is suppressed. The vibrations of the first frequency result from the hammering operation. The second frequency is different from the first frequency.

A hand-held impact tool includes a motor, a driving mechanism, a tool body, a main handle, a first detection part, a second detection part and a control part. The tool body is configured such that an auxiliary handle is removably attached thereto. The main handle is connected to the tool body. The first detection part is configured to detect selected one of a plurality of modes. The second detection part is configured to detect whether or not the auxiliary handle is attached to the tool body. The control part is configured to control operation of the impact tool based on detection results of the first detection part and the second detection part.

A drilling tool includes: a drive source; a bit attachment portion to which an end bit is attachable; a power transmission portion configured to apply a motive force to the end bit attached to the bit attachment portion; an operation portion switchable between an ON-state and an OFF-state by a manual operation and configured to receive a setting operation for setting a stop condition; and a controller configured to set the stop condition based on the setting operation, and to start driving of the drive source in response to a first switching operation for switching the operation portion from the OFF-state to the ON-state. In a state where the stop condition is set, even when the operation portion is in the ON-state, the controller stops driving of the drive source in response to the stop condition being met while the drive source is being driven.

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.

A control assembly for use with an electrical device to control operation of the electrical device in a plurality of operational modes.

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 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 remote demolition robot (10) comprising a controller (17), drive means (14), an arm member (11) movably arranged on a tower (10a) rotatably arranged on a body (11b) of the remote demolition robot (10) and a remote control (22) for providing commands, that are interpreted by the controller (17) causing the controller (17) to control the operation of the remote demolition robot (10), wherein the remote control (22) comprises a first joystick (24a) and a second joystick (24b), wherein the remote control (22) is characterized in that each joystick (24) is provided with a thumb control switch (26).
