Abstract
A transmission-controlling device includes a first circuit system, a second circuit system, and a selective switch. The first circuit system is to provide a first voltage. The second circuit system is to provide a second voltage. The selective switch responds to a user's operation to select the first or second voltage to drive the motor so as to change the rotational speed of the motor. The motor is adapted to a power tool and rotates a cutting blade of said power tool to process a workpiece. Thus, the present invention employs the selective switch to select the driving voltage for the motor to simplify and facilitate the switchover of the rotational speed of the motor.
