摘要： A hand-held power tool includes an electric motor, a tool unit, and at least one operating unit. A motor switching unit is configured to sense a contact-pressure characteristic between the tool unit and the operating unit, and configured to switch the electric motor at least partially in dependence on the contact-pressure characteristic.

摘要： An electrical device includes a control or regulating circuit and a plurality of electromechanical battery interfaces configured to supply the electrical device with a maximum permissible operating voltage using at least one exchangeable battery pack, which is releasably accommodated by the electromechanical battery interfaces. The electromechanical battery interfaces are configured such that exchangeable battery packs of at least two different voltage classes can be accommodated. The control or regulating circuit electrically connects several exchangeable battery packs of a lower voltage class in series and/or in parallel such that a resulting battery voltage does not exceed the maximum permissible supply voltage.
