A swinging space 4 located below the elastic rib 3 is provided between each of the buttons 1 and the corresponding connecting part 2. Based on the structure of the elastic rib 3, the two adjacent buttons 1 can swing downward relative to the connecting part 2 to achieve pressing.

[0025] The traditional switch group includes multiple independent buttons 1, each button 1 needs to be molded separately, and then combined through connecting parts such as pins. This method has high manufacturing costs and also requires the combination of multiple buttons 1. The present application obtains an integrally formed combination button through a pair of molds. The combination button includes at least two buttons 1 and a connecting part 2 for connecting the two. Elastic ribs 3 are provided on both sides of the connecting part 2, and there is a swing space 4 between the button 1 and the connecting part 2. Based on the structure of the elastic rib 3 and the swing space 4, the button 1 can swing downward slightly by utilizing the elastic deformation of the plastic, thereby touching the touch switch 16 of the circuit board 8 to realize functional output, saving manufacturing costs, and eliminating the need for manual combination of the buttons 1.

[0026] The upper end surface of the elastic rib 3 is lower than the upper end surfaces of the connecting portion 2 and the key 1. A groove 5 located above the elastic rib 3 is formed at the junction of the connecting portion 2 and the key 1, making it easier to press the key 1.
