The disclosure is based on a hand-held power tool having at least one switch device which comprises at least one switching element at least for activating a power supply of a drive unit, having at least one quick-change tool holder which is provided for holding an insertion tool which is different from an insertion tool with an SDS shaft having a maximum transverse extent of 10 mm and/or having at least one accumulator interface. It is proposed that the at least one switching device comprises at least one locking unit which is provided for maintaining, at least essentially independently of an effect of an operator activation force, an active operating mode which can be activated by actuating the at least one switching element.

A rotary hammer selectively operates in multiple modes including a first mode and a second mode. The rotary hammer includes a switch, a motor, a switch manipulation member, a locking member, and a mode detecting device. The switch manipulation member includes a body, and a protrusion that is movable between a protruding position and a retracted position. The body houses a solenoid configured to operate based on a detection result of the mode detecting device. The locking member is movable between an unlock position and a lock position where the locking member holds the switch manipulation member in an ON position by abutting the protrusion in the protruding position. The protrusion is integrated with a plunger of the solenoid. The protrusion is configured to be in the protruding position when the present mode is the first mode, and in the retracted position when the present mode is the second mode.

An impact tool includes a switch for driving the tool accessory, an operation member configured to be movable between an OFF position and an ON position, a first lock member configured to lock the operation member in the ON position, a second lock member configured to be movable between a lock position and a lock-release position in response to an external operation by a user, and a holding mechanism configured to hold the second lock member in the lock position and also in the lock-release position. The second lock member in the lock position is capable of locking the operation member in the OFF position, and the second lock member in the lock-release position is incapable of locking the operation member in the OFF position.

A handheld power tool has a monostable operating button 6 which has a stable switching position and a pressed switching position. A catch 32 which can be pivoted between a releasing position and a locking position in a pivoting direction 34 is provided, wherein the catch 32, in the locking position, stops the monostable operating button 6 in the pressed switching position. An operating knob 30 can be moved by the user in a shifting direction 31 which is perpendicular to the pivoting direction 34. The catch 32 is attached to the operating knob 30 by means of a joint 36. A slotted link 38 converts a movement of the catch 32 along the shifting direction 31 into a pivoting movement in the pivoting direction 34.

A hammer drill is provided including a motor, an electrical power circuit arranged to provide power to the motor, a tool holder arranged to hold a cutting tool, and a drive transmission operable in at least two modes of operation. A mode change mechanism is provided to switch the drive transmission between the at least two modes of operation, and at least one electrical switch is located within the electrical power circuit to provide power to the motor. Hammer drill further includes lock-on mechanism is configured to lock the at least one switch in the closed state when it is activated, a controller configured to control an operation of the motor, and an electrical power circuit configured to provide power to controller. The motor is prevented from operating when no power is provided to the controller.

A portable power tool is disclosed. The tool has a tool holder, a motor, a switchable gear stage, and a slider. The gear stage has a gear element movable in a switching direction with a toothing, which in a first gear position is engaged with a corresponding toothing and in a second gear position is disengaged. The slider is displaceable between first and second switch positions where the first switch position is allocated to the first gear position and the second switch position is allocated to the second gear position. A coupling device has a carriage movable in the switching direction and a catch. The carriage is connected to the gear element and the catch is latched in the first and second gear positions. A spring element has springy first and second sections. The slider has a finger that is arranged along the switching axis between the sections.

A hand-held power tool device, in particular a hammer drill and/or chisel hammer device, includes at least one operating element and at least one locking unit. The at least one locking unit includes at least one locking element and at least one controllable actuator element. The at least one locking element can be moved from at least one storage position into at least one locking position, and vice versa, and locks the operating element in at least one operating state in the locking position. The at least one controllable actuator element influences motion of the locking element.

A work tool, in which any one of a plurality of operation modes is selectable and which is configured to operate according to the selected operation mode, includes a switch for driving a tool accessory, an operation member, a mode switching member and a movement restricting mechanism. The operation member is configured to be held in an off-position in a non-pressed state and configured to move to an on-position in response to an external pressing operation. The mode switching member is configured to be switched between a plurality of switching positions in response to an external operation, the switching positions respectively corresponding to the operation modes. The movement restricting mechanism is configured to restrict a movement of the operation member from the off-position to the on-position in interlock with a switching operation of the mode switching member.

A hammer drill includes a switch, an operation member, a lock member, a mode switching member and a linked member. The operation member is normally held in an OFF position and moves to an ON position in response to an external pressing operation. The lock member moves in response to an external operation between a locking position, where the lock member is capable of locking the operation member in the ON position, and a non-locking position, where the lock member is incapable of locking the operation member. The linked member moves to an allowing position for allowing a movement of the lock member when the mode switching member is switched to a switching position corresponding to a hammer mode, and moves to an inhibiting position for inhibiting the movement of the lock member when the mode switching member is switched to a switching position corresponding to a drill mode.

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.
