ａ，１１ｂの長さの違いによりスイツチボタン１
ａが傾く状態で位置するという問題があつた。(c) Problems to be solved by the invention However, in the switch button 1a described above, burrs 11a and 11b of the mold part surface 10a during molding remain on the upper surface 6a of the locking piece 4a, and the supporting substrate 7a
When the locking piece 4a is inserted into the opening 17a of the support board 7a and is hooked, the locking piece 4a comes into contact with the back surface 8a of the support substrate 7a because the burrs 11a and 11b rise and contact the back surface 8a of the support substrate 7a. There is a point where there is no connection. Therefore, even when the switch button 1a is not pressed, it is positioned as low as the length of the burr 11a, causing the problem that the switch pressing portion 5a presses the switch 15a, resulting in malfunction. Also, two burrs 11
Switch button 1 due to the difference in length of a and 11b
There was a problem that a was located at an angle.

この考案は上記の事情に鑑みてなされたもので

されている。 As shown in FIG. 2, when the switch button 1 is molded, the mold part surface 10 is located on the reference surface 6 of the locking piece 4, and burrs 11 are likely to form on this reference surface 6. The height 12 of the convex portion 9 is set longer than the length 13 of the burr 11. The outer bottom of the hooking piece 4 is rounded.

する。 The switch pressing portion 5 is shaped like a round bar, and is inserted into a circular through hole 14 of the printed circuit board 7 to operate a switch 15, which is a contact point arranged below the printed circuit board 7. The switch pressing portion 5 is fitted into a spring 16 that provides an upward return force when the switch button 1 is pressed, thereby positioning the spring 16.

この考案のスプリングボタン１は上述したよう
に構成されており、以下に述べるように配置し用
いる。 The spring button 1 of this invention is constructed as described above, and is arranged and used as described below.

て上方へと立上る。 By fitting the switch pressing part 5 into the spring 16 (in the direction of the arrow in FIG. 3) and pressing the pressed part 2, the switch pressing part 5 is inserted into the rectangular insertion hole 17 provided in the printed circuit board 7. They are respectively inserted into the circular through holes 14 (see FIG. 4). At this time, the outer bottom of the hooking piece 4 is rounded to facilitate insertion. Further, the burr 11 protruding horizontally from the reference surface 6 of the locking piece 4 is pressed against the inner wall of the insertion hole 17 and rises upward.

い。 When the convex portion 9 reaches a position lower than the back surface 8 of the printed circuit board 7, the pressing of the pressed portion 2 is stopped. The switch button 1 returns upward due to the biasing force of the spring 16, and the upper surface 18 of the convex portion 9 comes into contact with the back surface 8 of the printed circuit board 7 and becomes stationary (see FIG. 5). At this time, the tip of the burr 11 rising from the reference surface 6 of the hooking piece 4 is at a position lower than the back surface 8 of the printed circuit board 7 because its length 13 is shorter than the height 12 of the convex portion 9. It never comes into contact with the back surface 8 of the printed circuit board 7. Therefore, when no pressing force is applied to the pressed surface 2, the switch button 1 is positioned lower than the predetermined state, and the switch pressing part 5
The switch 15 is not pressed into operation, and no malfunction occurs. Similarly, the upper surface 1 of the two convex portions 9
8 are equally located on the back surface 8 of the printed circuit board 7, so that the switch button 1 is not tilted.

(ト) 考案の効果 この考案は、立上つたバリが支持基板の底面に
