摘要（英）：

The utility model discloses a hatching machine touch button control cabinet which comprises a circuit board and a control unit arranged on the circuit board which is provided with a plurality of mutually independent electrode plates. A copper coating layer is on the circuit board and around the electrode plates. The circuit board is also provided with a digital tube which is electrically connected to the control unit. A touch plate is arranged above the circuit board. A metal spring piece is arranged between the circuit board and touch plate. The circuit board is also provided with a capacitance sensing circuit which is electrically connected to the control unit. The electrode plates are connected to the capacitance sensing circuit. According to the hatching machine touch button control cabinet, a capacitor is formed by the electrode plates arranged on the circuit board and the surrounding copper coating layer. When a finger touches the capacitor, the capacitance value is changed, the detection of the change of the capacitance value is used as the response of a touch button, the touch control principle is realized, and a series of problems of a mechanical button can be solved.
