The invention relates to a hand-held electric tool, which comprises a casing, a motor, a displacement pushbutton, an elastic piece, a
pressure sensor and a control
assembly, wherein the casing is provided with a
handle, the motor is accommodated in the casing and is used for driving a working head and controlling the rotation speed of the working head during working, the displacement pushbutton is arranged on the
handle and is pushed by an operator, the elastic piece is combined with the displacement pushbutton together, the
pressure sensor is connected with the elastic piece and is used for providing the outputted
voltage according to the position of the displacement pushbutton, the control
assembly is connected with the motor, and is used for making response to the outputted
voltage according to the position of the displacement pushbutton, so as to variably control the rotation speed of the motor. By adopting the structure, the overall size of a speed adjusting switch is greatly reduced, and the outer
diameter size of the
handle is further reduced, so the hand-held electric tool can be conveniently held and operated by a user with smaller hands.
