Abstract
A plurality of mode switches are electrically connected in parallel to a motor. A conductor plate has a plurality of electric current passages each connected electrically to one of the switches. Each of the passages has a length corresponding to a rotating angle for which the motor is set. A slider is connected to a power source and contacts the passages so that, when one of the switches is closed, the slider may cause an electric current to be supplied to the motor through the passage connected to the closed switch. The slider is slidable along the passages with the rotation of the motor. Each of the passages has a portion at which the contact of the slider therewith is broken so that the supply of the electric current to the motor may be interrupted.
