PURPOSE: A vacuum packing machine having a push switch is provided to reduce costs and to simplify the structure thereof by sealing a vacuum vinyl bag at a proper time without a vacuum pressure sensor. CONSTITUTION: A vacuum packing machine having a push switch comprises a lower case (110), an upper case (120), a lower packing (130), a vacuum pump, a heating bar, an upper packing (140), a press packing, a push switch (181), and a push protrusion (170). The lower case has an air inlet. The upper case opens and closes the top surface of the lower case. The push switch is installed on a substrate installed inside the lower case and starts the operation of the heating bar. The push protrusion is installed on a position corresponding to the push switch. When the lower and upper packings are pressed by the vacuum pump, the push switch is pressed by the clearance between the lower and upper cases.
