It is an exploded perspective view seen from the bottom. 11-14, the same code | symbol as FIG. 1 thru | or 10 shows the same or equivalent.

The basic structure of the pushbutton switch device in this modification is substantially the same as the above-mentioned embodiment, and the contact piece 62c of the press body 62 is removed, and the bottom surface of the front and rear surfaces of the operating body 68 is fitted. The difference is that the contact portion is brought into direct contact with the center of the front and rear ends of the press body 62 so that the press body 62 is pressed down.

In this case, since the press body 62 can be made small by eliminating the contact piece 62c of the press body 62, the whole switch apparatus can be miniaturized.

In addition, this invention is not limited to the above-mentioned embodiment, It is possible to perform various changes other than the above-mentioned, without deviating from the meaning.

For example, in the above-mentioned embodiment, the switch case 50 was started and the press body 62 and the operating body 68 were shown to have a rectangular shape in plan view, but these may be circular or other symmetrical shapes. It is satisfactory, and even in this case, the same effects as in the above-described embodiments can be obtained.

In addition, in the above-described embodiment, the push button 72 is configured to be detachably attached to the operating body 68, but the operating body 68 may be configured to integrate the push button 72.

Moreover, as a pushbutton switch device, it is not necessary to necessarily incorporate a light emitting element such as an LED or a lamp. The switch arranged in the switch case 50 is also not limited to the above-described tact switch 60.

In addition, although the spring 66 for adjusting the pressing force of the press body 62 is provided in the above-mentioned embodiment, it is not necessary to provide the spring 66 according to a pressing force, and you may delete it.

According to this invention, when the operating body is pressed, the operating body abuts against the center of the upper surface of the pressing body, and the pressing body moves downward against the upward pressing force. At this time, at the time of pressurization of the operating body, the pressing part of the operating body rotates downward with the engagement position along the pressing part of the operating body as a point.

Therefore, since the point corresponding to the pressing part of the operating body is switched, the distance between the pressing part and the point becomes almost the same even where the pressing part of the operating body is located, compared with the case where the point is fixed to one as in the prior art. The operating load can be made almost uniform regardless of the pressing portion of the operating body.

At this time, if a press body is pressurized with a press body, an operation load can be adjusted by pressurization of a press body upward.

Moreover, since the press body itself is formed by the elastic member, compared with the case where it presses by a press body, the number of parts can be reduced and it can comprise at low cost.

Furthermore, since the operating body is pressurized upward, the gap of the load of the pressing portion of the operating body can be reduced.

Moreover, by pressing a press body with a press body, an operation load can be adjusted, and pressurizing an operating body with another press body can reduce the gap of the load of the press part of an operation body.

Moreover, since the press body itself is formed by the elastic member and pressurized by the press body, an operation load can be adjusted. On the other hand, since the operating body is pressurized by another pressurizing body, it is possible to reduce the gap of the load on the pressing part of the operating body.

In addition, since the engaging portion of one end of the press body, the center of the switch, and the center of the switch case are arranged in the same line in a plan view, the operating body abuts against the center of the press body by the pressing of the operating body, and the pressing body is pressed down. In this case, the moment at the time of pressing the switch by the press body becomes almost constant irrespective of the operating part of the operating body, thereby ensuring uniformity of the operating load.

Moreover, since the plurality of engagement points of the operating body are formed at positions facing each other of the peripheral edge of the operating body, the distance between the pressing portion and the point of the operating body can be made almost the same regardless of the pressing portion. The uniformity of the operating load can be ensured.

In addition, part of each engagement point of the operation body is formed on the same side as one end of the pressing body to be caught, and the rest of each engagement point of the operation body is formed on the opposite side, so that the pressure of the operation body The distance between a site | part and a point can be made substantially the same irrespective of a press site | part, and the uniformity of an operation load can be ensured.

In addition, since the pressing body and the operating body are formed in a symmetrical shape such as a substantially rectangular or circular shape, the uniformity of the distance between the pressing portion and the point of the operating body can be easily ensured, thereby ensuring uniformity of the operating load. It is useful.

By the way, the pushbutton switch device of the present invention is not limited to application for an elevator as described in the above embodiments, but starts a so-called starter of a copying machine, and particularly incorporates a light emitting element to emit the presence or absence of switch operation. It is possible to apply to various switches for electronic devices which inform by the state.
