In the cited example, Japanese Unexamined Patent Publication No. 6 — 6 8 6 4 5 is shown as an example in FIG. 6. FIG. 6 is an explanatory diagram showing an example of a conventional push button switch device. Printed by the Consumers' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs {Please read the precautions on the back before filling out this page} As shown in Figure 6, it is composed of: fixed contacts 2 2 and 23 are arranged on the bottom of the interior. Bucket-shaped frame 21; made of an elastic conductive metal plate and bent into a generally U-shape to form a bent portion, and the bent portion will become a point of (force) force as the movable portion 2 4 of the movable contact member 2 5: and the operating (pressing) button 2 4 for pressing the movable portion 2 5 of the movable contact member 2 5 ^ The movable contact member 2 5 engages one end thereof Frame 2 1 side wall to form the fulcrum 2 7 The paper scale is applicable to China National Standard (CNS) 8 4 specifications (210X297 mm) 77 ~. 420819 A7 B7 V. Description of the invention (2), and the movable contact member The other end portion of 2 5 will be the movable contact portion 2 8 and will be configured to slide in the right direction in FIG. 6 as the movable portion descends and move it from the fixed contact 2 2 to the fixed portion. Contacts 2 3 come into contact. When the movable contact member 25 is in the non-pressed (advance) state when the operation button 26 shown in FIG. 6 is in a non-pressed (propulsed) state, the movable portion can be raised by its elasticity, and the movable contact portion 28 is from a fixed contact. At the same time, the 'operation button 2 6' is brought into contact with the fixed contact 2 2 while being separated. 2 9 is a fixed contact formed by insert molding on the supporting portion 2 1 a recessed 2 1 b formed on the inner side surface of the frame 2 1 and assembled as a fulcrum portion 2 5 of the movable contact member 2 7 The fixed contact 29 can be often contacted. 30 is used to operate the button 26 will not disengage from the frame 2 1 and can support the operation button 2 60% cover that can be moved up and down freely. 0 As described above, the button switch device can have fixed contacts 2 2, 2 The frame 2 of 3, the operation button 2 6 and the cover 30 of 4 components constitute 'so', which has the so-called miniaturization and the operation feel of the operation button 26 will also be smooth.

Point 2 2, 2 3 in the frame 'and the simple process of covering the upper part with the cover 30 can be completed. However, when the movable contact member 25 is inserted in the frame 21, it needs to be inserted into the fulcrum 2 7 contact the support 2 la recess 2 1 b bottom surface -5- (Please read the precautions on the back before filling in this page) This paper size applies to China National Standard (CNS) A4 specification (210X 297 mm) 420812 A7 B7 Economy Printed by the Ministry of Standards and Staff ’s Consumer Cooperatives 5. The fixed contact 29 of the invention description (3), and the movable contact portion 28 is brought into contact with the fixed contact 22, so that it has the disadvantage of being difficult to install from above . When the device operation button 26 or the cover 30 is moved, it may be moved to form an unstable state and inserted into the movable contact member 25 in the frame 21, so that the movable contact cannot be caused. The raising of the operation button 2 6 implemented by the component 2 5 becomes smooth, or the movable contact part 2 8 cannot be switched from the fixed contact 2 2 to the fixed contact 2 3. Even in an extreme state, when the cover body 30 is assembled, it may be possible to deform the movable contact member 25 by operating the button 2 6. However, such a disadvantage lies in that the aforementioned push button switch of Japanese Patent Laid-Open Publication No. 8-30003 has the same disadvantage. Also, the aforementioned push button switch device of JP-A No. 8-3 2 9 7 7 9 forms a fulcrum portion for locking the movable contact member on the operating lever, so that when the operating lever is assembled, the movable contact member may be caused Deformed. For this reason, the first problem of the present invention is to provide a push button switch device that is simple to assemble and that can cause a movable contact member to reliably switch. The second subject of the present invention is to provide a push button switch device that can increase the return (restoration) force formed by the movable contact member, and can quickly and reliably return the operation button and the movable contact member.
