坦をかける原因となる欠点が生じていた。 As a conventional push button switch structure, for example, the first
The one shown in the figure is often used. In the figure, 1 is a push button switch, 2 is a push button member, 3 is a slider member, 4 is a frame member, and 5 is a slider member 3
Both ends 5a and 5b of the spring member are supported by the support portion 3a of the slider member 3 and the support portion 4a of the frame member 4, respectively, forming coil springs 5'. In FIG. 1, when the push button switch 1 presses the push button member 2, the slider member 3 moves in the axial direction along the guide 6 provided on the frame member 4, against the spring member 5, and makes contact at the tip of the slider member 3. (not shown) acts as a switch. Here, the conventional push button switch 1 has a spring member 5.
Since the coil spring 5' is supported by the support part 3a of the slider member 3 and the support part 4a of the frame member 4 with both ends 5a and 5b located on the same axis, the pressing load applied to the push button member 2 is the second. As shown in the load characteristic graph in the figure, it increases in proportion to the stroke of the push button member 2 according to the spring constant of the coil spring 5', and within the range of the spring constant, it is only possible to adjust the increase in load. When the user uses the device for a long time, there is a drawback that it causes stress on the fingertips of the user.

ものである。 In A of the figure, the push button switch 1 of the present invention includes a push button member 2, a frame member 4, a slider member 3 that moves in the axial direction guided by a guide 6 of the frame member 4, and a coil spring 5' as a spring member 5. Both ends 5a, 5b of the coil spring 5'
are supported by the support part 3a of the guide member 3 and the support part 4a of the frame member 4, and the support parts 3a and 4b are not provided on the same axis, and the support part 4a of the frame member 4 is supported by the support part 4a of the frame member 4. The coil spring 5' is provided in an eccentric position opposite to the support part 3a provided on the movement axis of the slider member 3, and the coil spring 5' is supported in an eccentric buckled state in a substantially S-shape. Push button member 2 as shown in the middle
When a load is applied to the coil spring 5', the buckling point of the coil spring 5' moves according to the stroke of the slider member 3. Therefore, the load applied to the push button member 2 is sufficient to be a pressing force that displaces the buckling point of the coil spring 5, unlike the conventional example. Unlike a push button switch, the load acting on the push button member 2 does not increase in accordance with the stroke of the slider member 3, and the slider member 3 can be moved with a substantially constant load, so there is no resistance when using it, and it feels comfortable on the fingertips. This can reduce the burden on you.

5 shows a configuration in which a plate spring 5'' is buckled and supported in a substantially S-shape. FIG. 5 is a graph showing the load characteristics of the present invention. In addition to the spring constant of the spring member 5, the present invention By changing the spring free length, the spring fixing position or eccentricity, and changing the amount of buckling of the spring member 5, the load range can be freely set within a predetermined range not only in the direction of increase but also in the direction of decrease, as shown in the figure. This configuration allows the push button switch 1 to be given various load characteristics.

The contact plate 7 is secured by the locking plate portion 3b of the slider member 3.
This figure shows another embodiment in which the push button switch 1 is made to have a light click feeling when the push button switch 1 is applied. It shows
In this embodiment, the push-button switch 1 is a push-button switch that returns to a constant load after receiving resistance to an increase in load that gives a click feeling at a predetermined stroke position.
