押釦の傾きを防止するようになつている。 Next, to explain the operation of the present invention, push button 1
When 9 is pressed, the arcuate band 16 of the upper contact member 14 is inverted downward and comes into contact with the lower contact member 13 in the first operating position, and the terminals 12a and 5a are brought into conduction. Next, when the push button 19 is further pressed, the contact member 13 comes into contact with the center contact 6, and the terminals 12a,
5a and 6a are all in a conductive state. Next, when the pressure is removed, the conduction between the terminals is sequentially released in the reverse order. Since the peripheral portion of the lower contact member 13 is fixed within the recess 3 of the housing 1, the contact member 13 does not jump up when returning to its original shape, and therefore avoids unnecessary contact with the upper contact member 14. is prevented from doing so. Furthermore, the push button 19 is connected to the top plate 23.
The guide wall 25 is loosely fitted to prevent the push button from tilting when pressed.

の顕著な効果を奏する。 As mentioned above, the present invention simplifies the complicated structure such as the holding plate in the conventional structure, and by fitting a part of the annular surface inside the casing, the lower movable contact member can be moved to the upper part without moving upward. Unnecessary contact with the movable contact member can be prevented. Furthermore, since the push button is loosely fitted into the guide wall of the top plate, it is possible to prevent the push button from tilting when the push button is moved up and down, making the movement smooth and providing a good pressing feel. Furthermore, there are significant effects such as the ability to reduce the thickness of the switch and make it even more compact.
なお、押釦の形状は角形に限定されるものでは
なく、円柱状の押釦を、円筒状の案内壁を備えた
上面板に遊嵌させてもよく、かかる構成も本考案
の登録請求の範囲に属すること勿論である。 Note that the shape of the push button is not limited to a rectangular shape, and a cylindrical push button may be fitted loosely into a top plate provided with a cylindrical guide wall, and such a configuration is also within the scope of the registered claims of the present invention. Of course it belongs.
