摘要： 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.

摘要： Methods for counterbalancing a weight force of an object fastenable to a traction cable. A system is configured to carry out a counterbalancing operation with respect to the weight force of the object. This counterbalancing operation can be performed in that a rotational speed of the motor and/or a derivation of the rotational speed of the motor is determined, wherein a current setpoint value can be stored as a controlled variable in the system. The rotational speed of the motor or a derivation thereof corresponds to a weight force of the object. Alternatively, a current value required for maintaining the first position of the object or a motor torque required for this purpose can be stored in the system and the weight force of the object can be counterbalanced using the previously stored current values or torques. In further aspects, the invention relates to a system and to an electronic module.

摘要： A hand-held power tool has a tool holder for holding a tool, an electric motor for driving the tool holder, and a handle for holding and guiding the hand-held power tool. A button has a button housing, a pin that can be moved on an actuation axis, and an electric slider which is connected to the pin and which slides on an electric slider track. The button housing is suspended in the handle in such a way that the button housing can be pivoted about a pivot axis perpendicular to the actuation axis.
