In the figure, 1 is a reinforcing plate made of metal or the like.
The membrane switch 2 is placed on the top. The membrane switch 2 is an upper sheet 2b having a movable contact 2a.
And a lower sheet 2d having fixed contacts 2c. A case 3 is placed on the membrane switch 2, and the case 3 is provided with a first protrusion 3a and a second protrusion 3b formed in an annular shape. The operating member 4a of the key-up 4 is slidably positioned on the inner wall 3c of the shaped portion 3a, and the engaging claw provided at the lower end of the operating member 4a is formed in the cutout concave portion of the first protrusion 3a. The engaging claws (not shown) slide in the notch recesses, and the operating member 4a is configured to be slidable in the vertical direction on the inner wall 3c. A coil spring 6 is interposed between the flat surface 3d of the case 3 and the lower surface of the key top 4 so as to be located around the first protrusion 3a. Further, a coil spring 5 for pressing the movable contact 2a of the membrane switch 2 by strong fitting is attached in the operating member 4a. Although not shown in FIG. 3, a notch recess is provided in the second protrusion 3b in the direction orthogonal to FIG. 3, and the engaging claw provided on the key top 4 is attached to the notch recess. This prevents the key top 4 from slipping upward.

When the key top 14 is pressed under the above configuration, the key top 14 moves downward against the spring pressure of the coil spring 16 for upward biasing. At this time, the engaging claw 14b of the operating member 14a is a sliding member.
When the lower surface 14d of the key-top 14 contacts the upper surface of the sliding member 15, the engaging claw 15c of the sliding member 15 moves in the notched groove 13c when the lower surface 14d of the key-up 14 abuts on the upper surface of the sliding member 15. . Therefore, the outer peripheral surface of the operating member 14a slides on the inner peripheral surface of the sliding member 15, and the outer peripheral surface of the sliding member 15 is the first projecting wall 13a of the case 13.
Slide on the inner surface of. The lower end of the coil spring 17 attached to the operating member 14a causes the membrane switch 12
The upper sheet 12b of the is pressed and the movable contact 12a is fixed.
Contact c and switch turns on. At the same time, the lower surface 14d of the keep-up 14 comes into contact with the upper surface of the first protruding wall 13a. When the pressing of the key-top 14 is released, the coil spring 16 returns to its original state by the elastic restoring force of the coil spring 16.

On the other hand, the conventional push button switch is H = 2S + a, and a = H-
It becomes 2S. (However, the thickness b of the key top 14 and the reinforcing plate 11
Since the thickness c of the membrane switch 12 and that of the membrane switch 12 are similar to those of the present invention in the related art, they are excluded from the calculation formula. ) Therefore, if you make a difference from the configuration of the present invention to the conventional configuration Next to Becomes Therefore, in the structure of the present invention, when the height H of the pushbutton switch is the same as that of the conventional example, the engaging portion E may be configured to be 1 / 2S larger than the conventional engaging portion a. it can. Therefore, when the amount of movement is set to 3 mm, for example, the conventional engaging portion a + 1.5 mm can be made longer, so that the height of the push button switch can be lowered by that amount and the thickness can be reduced, and the key top 14 Even if the end portion is pressed, the key top 14 is not tilted and pressed.
