【Example】

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is one of the present invention It is a perspective view showing an operation switch concerning an example. FIG. 2 is a sectional view thereof.

[0009]   In the figure, 3 is a switch contact, which is pressed by the switch operating unit 4. It is something. 7 is a switch terminal. 20 is a holding part formed in a box shape Is. This holding body 20 is divided and the upper side is the switch operating portion 4 and It is configured as the switch body 1 that holds the switch contact 3, and the lower side is the switch terminal It is configured as a switch terminal holding unit 2 that holds 7. This switch body 1 And the switch terminal holding portion 2 are provided with engaging step portions at their peripheral portions so that they can be engaged with and disengaged from each other. Has been formed.

[0010]   Further, on the outside of the switch body 1, a hole is formed in the switch reinforcing plate 9 of the device housing 10. The switch holding fixed arm 13 for holding the switch body 1 on the switch reinforcing plate 9 Is provided.

[0011]   Further, the switch terminal 7 projects inside and outside the switch terminal holding portion 2, A terminal whose inside contacts the pressed switch contact 3 via the contact portion side contactor 6. Is formed as the part side contactor 5, and the outer side is provided with a fixing agent 11 such as solder on the electronic circuit board 8. And then connected. Reference numeral 12 is an electronic component of the electronic circuit board 8.

[0012]   That is, in the operation switch according to the present embodiment, the switch body 1 has the switch terminal protection. It has a structure that can be separated and reattached to the holding part 2, and it can be connected to the switch contact 3 and the switch.
