ABSTRACT:
The process of controlling rotational speed of an electric motor of an electric hand tool, including providing an electric motor of an electric hand tool with a rotational speed control comprised of displacement means for providing displacement in response to manual operation of the electric hand tool selected from the group consisting essentially of a linear displacement device for providing linear displacement (s) and an actuating dial for providing arcuate displacement (S); an elastic membrane to which the displacement means is articulatedly connected so that during displacement of the displacement means the elastic membrane deforms as a function of the displacement; actuating means comprising a sensor element coupled to the elastic membrane so that the sensor element produces an electrical output variable as a function of the deformation of the elastic membrane, the sensor element being selected from the group consisting essentially of a Hall sensor, an inductive sensor, and a sensor switch; and an electronic switch for rotational speed control connected to the actuating means, from which it receives the electrical output variable, and to the electric motor of the electric hand tool; and manually operating the displacement means of the rotational speed control to control the rotational speed of the electric motor.
