PROBLEM TO BE SOLVED: To provide a push button switch mechanism having a structure in which a pressure direction of a keytop and a pressure direction of a push switch pressed by the keytop are different from each other, and having a simple structure, and that can be miniaturized.SOLUTION: A push button switch mechanism comprises: a push switch 11 installed on a surface of a circuit board 10; a keytop 60 having a pressing part 63 moving in a direction along the surface of the circuit board 10; and a rotation member 30 mounted on the surface of the circuit board 10, and having a pressed part 39 opposed to the pressing part 63 of the keytop 60, a switch pressing part 37 opposed to the push switch 11, and a fulcrum 45 serving as a rotation center. The pressing part 63 of the keytop 60 presses the pressed part 39 of the rotation member 30, and this rotation member 30 rotates around the fulcrum 45, and thereby, the push switch 11 is on-off operated by the switch pressing part 37. |
