  • Push-button switch structure and electronic device having same
    Patent number: 8946575
    Abstract: A switch through hole 22 is formed in a front cabinet 5a, and a press switch 21 is located in the front cabinet 5a to correspond to the switch through hole 22. With a pressing element 25 inserted in a plate through hole 28a of a reinforcing plate 28, an outer periphery of a middle portion of the pressing element 25 in an axial direction and the plate through hole 28a are connected by a silicone rubber 27. A key top 26 is coupled to one end of the pressing element 25 in the axial direction so as to be exposed from the switch through hole 22, and a switch assembly 24 is fitted in the switch through hole 22. This structure increases durability of a push-button switch, while increasing ease of assembly of a push-button switch structure.
