Abstract
An electric hand tool has an electric consumer, a movable operating element and a control unit for controlling a current flow between the energy store and the consumer on the basis of the position of the operating element. The control unit is constructed separately from the operating element and the mechanical position of the operating element is converted into an electrical control signal in the control unit.
