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