性が良好となる。 Due to the elastic force of the return spring 11, the movable contact plate 1
0 is biased in a direction away from the fixed contact 7.
Also, by locking both ends 11b and 11c of the coil portion 11a as described above, the coil portion 11a
falls toward the movable contact plate 10, and as a result, the base of the movable contact plate 10 is pressed toward the other bearing part 22 and comes into close contact with the inner surface of the bearing part 22 , so that the contact mounting plate 1 and the movable contact Electrical connectivity between the plates 10 is improved.

半田付により接続される。 The push button switch having the above configuration has a button 13 fixed to a movable contact plate 10 in a switch case C.
It is fixed to the switch case C by screwing a screw (not shown) into the switch case C through the screw insertion hole 5 of the switch mounting part 6. The positive lead wire l 1 is wound around the groove 4 of the lead wire connection portion 3 on the contact mounting plate 1 and connected by soldering, and the fixed contact 7
The negative lead wire l2 is connected to the lead wire connection portion 7b by soldering.

熱によるへたりを防止することができる。 In the above configuration, when the movable contact plate 10 is swung counterclockwise in FIG. 2 by pressing the button 13, its contact portion 10a contacts the contact portion 7a of the fixed contact 7. The paths of the positive lead wire l 1 , the contact mounting plate 1, its bearing portion 2 2 , the movable contact plate 10, the fixed contact 7, and the negative lead wire l 2 and the bearing portions 2 1 and 2 2 are connected via the support shaft 9. movable contact plate 10
The path leading to the terminal is energized, and a predetermined circuit is closed. As a result, almost no current flows through the return spring 11, which has a relatively high resistance, so that it is possible to prevent the return spring 12 from becoming sagging due to electrical heating.

化を図ることができる。 Furthermore, there is no need to form a special current-carrying path between the movable contact plate and the contact mounting plate, and the return spring also has the function of bringing the movable contact plate into close contact with one of the bearings. The number of parts can be reduced compared to the case where this function is performed by a separate spring, thereby making it possible to downsize the switch and simplify its configuration.
