Abstract

(57) [Summary] [Purpose] The present invention is to provide an inexpensive push switch that requires fewer assembly steps. In particular, the purpose is to eliminate the use of conventional metallic coil springs. [Structure] The present invention is a push switch used for panels, etc., which is composed of a push button 2, an elastic part 3 for restoring the push button to the position before being pressed, a guide pin 8, and a stopper part 5. It is integrally molded from resin.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a push switch.

0002

[Conventional technology]

In general, push switches using push buttons used on the panels of electronic devices are conventional. As shown in Figure 2, a guide pin is provided in the center of the back of the push button. A metal coil spring was inserted into this and a push switch was assembled. This group In the vertical position, coil springs and assembly man-hours were required. Also, using a coil spring automatic insertion was difficult.

0003

[Problem that the idea aims to solve]

The purpose of this invention is to provide an inexpensive push switch that requires fewer assembly steps. . In particular, the purpose is to eliminate the use of conventional metallic coil springs.

0004

[Means to solve the problem]

The present invention is a push switch for use on panels, etc. Elastic parts, guide pins and stops to restore the button to the position before it was pressed. The pad part is integrally molded from synthetic resin.

[0005]

[Effect]

According to this invention, when force is applied to the pushbutton and the force is released, the pushbutton The force to restore the position to the position before applying force is provided on the back of the push button integrally with the push button. Utilizes a large elastic part.

[0006]

【Example】

Next, an embodiment of the present invention will be described with reference to FIG. In Figure 1, 1 is the panel of an electronic device, and its surface has switches, displays, and lighting devices. lighting equipment etc. are installed. 2 is a push button made of synthetic resin. Suitable materials include ABS resin. It will be done. This ABS resin has strength and elasticity, and by making it into a plate shape, it can be used as a coil spring. It is a substitute for 4. 5 is a stopper part integrally molded with the push button 2, and two stoppers are provided. ing. However, for stability, it is better to have three or more. installed at the tip of the stopper part 5. The cut hook part 6 is hook-shaped, so it is easy to insert during assembly, and the hook part expands after insertion. It has a structure that prevents it from falling out.

[0007] 3 is an elastic part that is molded integrally with the push button 2 and the stopper part 5, and is It has elastic plate-shaped ribs that extend outward from the base and have an arc shape. Also stock It has the same number as the stopper part, and the length is about half that of the stopper part. 7 is in panel 1 This is a hole through which the cut stopper portion 5 passes.

[0008] 8 is a guide pin, and 9 is a hole drilled in panel 1 through which the guide pin passes. be. The guide pin is located in the center of the back of the pushbutton and allows you to press the pushbutton. When the tip 11 presses the contact pressing section 12, the switch section 13 is operated. 10 is the base of the guide pin, and the base has a thick diameter as shown in Figure 1. Both are integrally molded with the push button. By making this shape, the hook part 6 and Both regulate the length of the stroke and also serve as a stopper. As a result, the bullet The sexual parts also have a long lifespan because they are not subjected to critical force. In FIG. 3, the elastic part 3 is projected inward from the stopper part side. Furthermore, the guide pin base Even if the diameter of the part is the same as that of the guide pin and a step 14 is provided on the panel side as shown in Figure 2, good.

[0009]

[Effect of the idea]

As described above, according to the present invention, the stopper part, the elastic part, and the guide are provided on the back side of the push button. By integrally molding the pin with resin, a coil spring is no longer necessary, making it possible to eliminate parts and It is possible to reduce man-hours. Furthermore, assembly is just a matter of pushing in one direction from the top. suitable for automatic insertion.
