Description

[Detailed Description of the Invention] A. Technical Field of the Invention The present invention relates to a switch operation button that rotates about the base by pressing the tip and opens and closes the switch with the switch pressing part.

B. Prior art and its problems Conventionally, vending machines have been provided with a large number of selection switches, each of which is operated by an operation button as shown in FIG.

That is, the operation button 1 consists of a rectangular tube-shaped button body 2 made of synthetic resin and a cover 6, and two claw pieces 3 are provided protruding from both sides of one side of the button body 2.
One claw piece 4 longer than the claw piece 3 is located in the center on the opposite side.
is provided. And, inside the claw piece 4,
A switch pressing section 5 is provided for pressing a push button 10 of a switch 8, which will be described below. Further, the cover 6 is provided with a flange 7.

The operation button 1 having the above structure is mounted in an opening 12 of a base plate 11 having a switch 8 below, with the claw pieces 3 and 4 being deformed by their elasticity. Note that, as mentioned above, since the claw piece 3 is short, the board 1 should be attached with a slight margin between the claw part 3a and the flange 7.
1 to form a fulcrum part S. On the other hand, since the distance between the flange 7 and the claw part 4a of the claw piece 4 is long, the operation button 1 rotates between the claw part 4a and the flange 7 about the fulcrum part S, and presses the push button 10 of the switch 8. It is designed to be opened and closed by part 5.

By the way, since the return force of the operation button 1 is obtained from the push button 10 of the switch 8,
There is also a limit to the miniaturization of the switch 8 because it is desirable to have a large stroke to confirm the operation of the operation button 1.

In addition, in Japanese Utility Model Application Publication No. 58-184730, the other end of an operation button whose one end is rotatably supported is extended outward, two elastic pieces are formed in this extended part, and one of them is It has been proposed that one elastic piece is placed in contact with the base, the other side is placed opposite the operating rod of the switch, and when an operating button is pressed, one elastic piece obtains a restoring force to open and close the switch.

However, the elastic piece protrudes outward from the operating button in order to have a function of preventing the operating button from being removed. That is, since the switch is also disposed at a position offset from the bottom of the operation button body, the occupied area including the switch is large, which is inappropriate when a large number of small operation buttons are mounted closely together.

On the other hand, in recent years there has been a demand for smaller selection switches in vending machines and the like, but the conventional ones have had the drawback of not being able to adequately meet this demand for the reasons mentioned above.

C. Purpose of the invention The present invention is designed to obtain the return force of the operation button by modifying the operation button, instead of obtaining it by the return force of the push button of the switch as in the past. It is an object of the present invention to provide a switch operation button that can be set below the operation button and eliminates the above-mentioned drawbacks of the conventional switch operation button.

D. Structure of the Invention In order to achieve the above object, the switch operation button of the present invention is latched to the edge of the opening provided in the substrate with claw pieces of different lengths which are protruded downward while facing the switch operation button of the invention. In a switch operation button that opens and closes a switch located below by pressing the upwardly protruding button body through a return means and rotating the short claw one side base as a fulcrum, the return means is connected to the switch operation button body. An elastic piece is provided that protrudes inward from the wall surface so that its tip comes into pressure contact with the main body of the switch, and a switch pressing portion is provided approximately at the center of the operation button.

E. Description of the embodiments Figures 1 to 4 show the first embodiment of the present invention;
Components that are the same as those in FIG. 8 are designated by the same reference numerals and their description will be omitted.

That is, in the present invention, from both sides of the side wall opposite to the fulcrum part S of the button body 2, the 2
In addition to providing elastic protrusions 13, 13, an elastic push button operation piece 15 is provided in parallel between the elastic protrusions 13, 13 and from the side wall on the fulcrum S side.

In addition, 14 is a crimping part, and 16 is a fulcrum part.

When the elastic protrusions 13 and 13 are attached to the operation button 1 by inserting and engaging the claw pieces 3 and 4 into the opening 12 of the base plate 11, the crimping portions 14 of the elastic protrusions 13 are attached to the push button 10 of the switch body 9. It is designed to come into pressure contact with the upper surface on the opposite side. Further, in this case, the pushbutton operation piece 15 is located above the switch body 9.

In the above state, when the operation button 1 is pressed, the operation button 1 moves against the elasticity of the elastic protrusion 13 and moves to the fulcrum part S.
Rotates around. Along with this, the pushbutton operation piece 15 also rotates, and eventually its fulcrum 16 is pressed against the upper surface of the switch body 9, and then the tip of the pushbutton operation piece 15 presses the pushbutton 10, opening and closing the switch 8. do.

Next, when the pressure on the operating button 1 is released, the operating button 1 returns to its original position by the elasticity of the elastic protrusion 13.

In the embodiment described above, the elastic protruding piece 13 was shown to protrude from the side opposite to the fulcrum part S, but it may be made to protrude from the fulcrum part S. Further, the push button operation piece 15 does not necessarily have to be elastic, but if it is configured as in the embodiment, even if the operation button 1 malfunctions due to impact, the shock will be cushioned and the switch will be activated. Damage can be prevented. Furthermore, the push button operation piece 15 is moved to the fulcrum portion S.
Of course, it is also possible to protrude from the opposite side.

5 to 7 show a second embodiment, in which lamp mounting holes 17, 17 are provided in the button body 2, and while a lamp is mounted, a message such as "on sale" or "sold out" is displayed on the cover 6. Apply operation button 1
may be provided with a display function.

F. Effect of the invention As described above, the return force of the operation button 1 is provided by the elastic protrusion 13 provided inside the button body 2, and since the stroke is also sufficient, the switch 8 is also smaller than the conventional one. can be applied. In addition, not only the elastic protrusion 13 but also the push button operation piece 15 is located inside the button body 2 of the operation button 1, and the operation button 1 itself can be small, and the switch 8 can be installed below the operation button 1. The switch structure can be made compact as a whole.
