An electric rotational tool driving switch system, which, in using an electric rotational tool, is capable of selectively effecting drive control based on a desired push operation type or lever operation type according to individual work contents and which is easy to handle, with sufficiently enhanced safety, wherein a rotational tool (14) is constructed such that a drive switch (30) of push operation type adapted to effect ON-operation by abutting against a work subject, such as a screw, to cause push displacement thereof, and a drive switch (32) of lever operation type adapted to effect ON-operation by push-displacing a switch lever (26) disposed in the grip of an electric rotational tool are respectively combined with magnets (31a, 33a) and magnetic sensors (31b, 33b), the magnetic sensors being connected to the energization circuit of an electric motor (12), one of the above-mentioned operation types being selected so that the magnetic sensing action of the magnetic sensor based on the selected operation type is used to turn on the energization circuit so as to start the electric motor.
