Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a push button device capable of seesaw movement, such as a tuning button of a radio receiver, which performs opposite movements such as up and down.

2. Description of the Related Art In general, this type of push button device has a push button body 6, as shown in FIGS. 4 and 6. The shaft Sa, which is composed of a cabinet 6, a panel 7, and a spring 8, and which is integral with the push button body 6, is inserted into a bearing 6a of the cabinet 6 and then fixed to the panel 7. Further, a spring B is disposed between the cabinet 6 and the push button body 6 in order to restore the push button body 6 after operation. Further, on the printed wiring board 4, the legs 6b of the push button body 6 are provided.
A touch switch 3 is arranged below.

Problems to be Solved by the Invention However, in such a push button device, a separate spring 8 is required to return the button after operation, and the push button body 6 is fixed by the cabinet 6 and panel 7, which increases the number of man-hours. - There was a problem of increased material costs.

Means for Solving the Problems The push button device of the present invention engages the ends of two molded springs that are integral with the cabinet and bent in the button insertion direction with claws at the ends of the legs of the push button body that fit into the cabinet. It is configured as follows.

Function: In the push button device of the present invention, since the molded spring integrated with the cabinet is bent in the button insertion direction, the molded spring and the legs of the push button body are bent when the button is inserted, so that the push button body can be easily attached to the cabinet. I can do it. After the push button body is inserted into the cabinet, the claw on the push button body and the molded spring are fitted, so the spring is deformed during operation.
After operation, it has to be returned to its original position, and has the advantage of having only two parts.

Embodiments Hereinafter, push button devices according to embodiments of the present invention will be explained with reference to the drawings. FIGS. 1 and 2 show a plan view and a sectional view of an embodiment of the present invention. Further, FIG. 3 shows a perspective view of the embodiment in an exploded state.

In Figures 1 to 3, the push button body 1 and the cabinet 2 are
The push button body 1 is integrally molded with the claw 1b at the end of the leg 1a, and the cabinet 2 is molded integrally with the end of the molded spring 2a bent in the inserting direction of the button. Ru. Further, the positioning pin 1d of the push button body 1 is inserted into the positioning hole 2b of the cabinet 2, and the button leg 1C is inserted into the positioning hole 2b of the cabinet 2.
is inserted into the positioning groove 2C and positioned. Further, the touch switch 3 is fixed on the printed wiring board 4 with an appropriate gap from the tip of the leg 1N.

During actual assembly, as shown in Figure 3, the elastic legs 1
A pushes the elastic molded spring 2a, and the tip of the molded spring 2B engages with the claw 1b at the tip of the five legs 1a, so that they are finally fitted. In actual operation, the push button body 1 is tilted so that the raised claw 1b pulls up the molded spring 2a, and returns naturally with this elasticity.

Effects of the Invention As described above, the push button device of the present invention has a molded spring that is integrated with the cabinet and bent in the button insertion direction, and a push button body that has a claw that engages with the molded spring, so that one-touch assembly is possible. Moreover, the number of parts is small, and it is extremely advantageous in practice.
