A multivibrator circuit has one series circuit including a first resistance and a first capacitor and determining a first switching time, and another series circuit including a second resistance and a second capacitor and determining a second switching time, a potentiometer having an arm that establishes a first resistance subregion and a second resistance subregion of the potentiometer, wherein the first resistant subregion constitutes the first resistance and the second resistant subregion constitutes the second resistance; also there are provided an electric hand tool having an electric motor and the multivibration circuit that influences a delivery of power to the electric motor, a use of a multivibrator circuit for generating a pulse width modulated signal for triggering an electric motor of an electric hand tool, and a method for variably adjusting a first and a second switching time of the multivibrator circuit.
