Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device capable of smoothly performing a switching operation of switches.

[0002]

2. Description of the Related Art As shown in FIGS. 1 and 2, a known switch device mainly has a pressing member, a holding frame body with which the pressing member engages, and a pedestal. As shown in the figure, in such a known switch device, the outer side wall 10 of the pressing member 1'is
The protrusions 11 are provided at the central positions of a ′ and 10b.
a'and 11b 'are formed and the protrusions 11a', 11
Engagement portions 12a ′ and 12b ′ are formed on the b ′ toward the outside from the outer side wall, respectively. Also,
On the inner side walls 20a ', 20b' of the holding frame body 2 ', recessed grooves 21a', 21b 'which are recessed from the inner side wall surface are formed at positions facing the engaging portions 12a', 12b 'of the pressing member. , The engaging portion 22 in the groove 21a ', 21b'
a 'and 22b' are provided and configured.

In such a structure, when the pressing member 1'is combined with the holding frame body 2'from below the holding frame body 2 ', as shown in FIG.
a ', 11b' are inserted into the concave grooves 21a ', 21b', and the engaging portions 12a ', 1'of the protrusions 11a', 11b 'are
2b ′ is the inner side walls 20a ′, 20 of the holding frame 2 ′.
Locking portion 2 formed on protrusions 11a 'and 11b' of b '
2a ', 22b' are engaged with the locking portions 22a ', 22
Since it is locked by b ', the pressing member does not come off from the holding frame body 2'.

Further, as can be seen from the disclosure of FIG.
Such a publicly known switchgear device is designed by an engaging method, and the outer surfaces of the engaging portions 12a ', 12b' of the pressing member 1'are formed in a flat shape, and this surface is the holding frame body 2. Since the inner side walls 20a 'and 20b' of the switch contact each other face-to-face, when the user of the switchgear device pushes the pressing member with his finger to switch the switch, the pressing member incorporated in the holding frame is moved up and down. Even if it is swung in the direction, the phenomenon such as shaking does not occur.

[0005]

However, in such a known switchgear device, the engaging portions 12a 'and 12b' are provided.
And the inner side walls 20a 'and 20b' of the holding frame body 2'are in face-to-face contact with each other, a large friction resistance force is generated when the pressing member is swung, and the user presses with force. I have to push the parts, so I don't feel smooth. Further, due to the large frictional resistance, the wear of the member is remarkable, and the connection between the pressing member 1'and the holding frame body 2'is likely to loosen. Therefore, when the pressing member 1'is swung when the switch is switched, the phenomenon of shaking easily occurs, and the life of the switch device is shortened.

In view of the design drawbacks of the known devices described above, the inventor has conducted diligent research and, after many times of design and experiments, has solved the drawbacks found in these known devices. We succeeded in developing an improved structure.

An object of the present invention is to suppress the frictional resistance force generated between the pressing member and the holding frame body, and to shake when the pressing member assembled to the holding frame body is pressed and rocked. An object of the present invention is to provide a switchgear device in which the occurrence of a phenomenon is effectively suppressed.
