い。Further, in the above embodiment, the bottom plate 55 is fixed to the holding plate 57 in a state where the hinge portion 81 is curved, but the hinge portion 81 may be broken at this time. However, in the case of the present invention, the plurality of protrusions 79a to 79d of the holding plate 57 are formed in the through holes 7 of the bottom plate 55.
Since the structure is such that they are inserted into 7a to 7d and fixed, there is no possibility that the fixation of both will be weakened by cutting the hinge portion 81.

易である。Particularly in the case of the present invention, since a plurality of protrusions provided at substantially equal intervals around the through hole of the holding plate are inserted and fixed in the through holes provided in the bottom plate, even if the hinge part is broken, However, there is no problem in fixing the holding plate and the bottom plate. Moreover, even if the plurality of projections of the pressing plate are respectively inserted and fixed in the through holes of the bottom plate in order to ensure the fixation of both, the present invention separates the pressing plate and the bottom plate by a predetermined distance. Since they are connected by the hinge portion, it is easy to insert the protrusion of the pressing plate into the through hole of the bottom plate.
（３）この押釦スイッチを回転式可変抵抗器等の回転式
電子部品の下端に取り付けた場合であって、この押釦ス
イッチが故障したような場合、前記回転式可変抵抗器の
各構成部品を分解することなしに該押釦スイッチの修理
をすることができ、その作業が容易となる。(3) When this push button switch is attached to the lower end of a rotary electronic component such as a rotary variable resistor and the push button switch fails, disassemble each component of the rotary variable resistor. The push button switch can be repaired without doing so, and the work is facilitated.
