ばね定数ｋを与えてある。FIG. 1 shows a first embodiment of the present invention, and FIG. 2 is a diagram for explaining its operation. A switch button 1 for operating a switch from outside the device includes a switch operating portion 11, a fixed portion 12, and a hinge portion 13, which are integrally formed. Reference numeral 2 is a tact switch, and 3 is a circuit board to which the tact switch 2 is attached. The housing 4 supporting the switch button 1 is formed integrally with a guide rib 41 that guides the circuit board 3. 5
Is a buffering mechanism composed of a spring of a buffering means, and the circuit board 3
Intervening between the holder 7 and chassis 6 attached to
It supports the circuit board 3. Further, the buffer mechanism 5 is provided with an appropriate spring constant k in order to prevent the tact switch 2 from being overloaded.

損することはない。In the switch mechanism constructed as shown in FIG. 1, when the switch button 1 is pushed in the direction of the arrow as shown in FIG. 2, first, a pushing force acts on the tact switch 2 to complete the switch operation. . At this time, even if the pushing force is excessive or shocking, the tactile switch 2 is damaged because the buffer board 5 moves and absorbs the pushing force while holding the circuit board 3 on the guide rib 41. There is no such thing.
