2. Description of the Related Art FIG. 3 shows a conventional push-button switch device in which a plurality of push-button units are vertically arranged on the front of an electronic equipment housing. In FIG. 3, reference numerals 2 and 3 denote plate-shaped relay members having one ends integrally connected to the straight fixed bar 1 and arranged so as to be parallel to each other. The button portions 4 and 5 are formed integrally, and the relay member 3 is formed in a substantially L-shape so that the push button portion 5 is arranged at a position above the push button portion 4.

Further, switch pressing members 6 and 7 are integrally formed so as to protrude at right angles from the intermediate portions of the relay members 2 and 3, respectively, and the fixed bars 1 of the relay members 2 and 3 are formed. Near the connection with
Thin portions 8 and 9 are provided as pivot points, respectively, and 1 to 9 are integrally formed of a synthetic resin material.

When the switch is operated, the push button unit 4
Alternatively, by the pressing of 5, the relay member 2 or 3 is independently deformed elastically so that the tip thereof draws an arc-shaped trajectory around the thin portion 8 or 9, and with this deformation, the switch pressing is performed. The member 6 or 7 also pivots about the thin portions 8 and 9 as pivot points and independently and selectively presses the switches 12a and 12b disposed on the electronic wiring board 13 disposed horizontally in the housing. It is configured to be.

At the time of assembling into the electronic device, the fixing bar 1 is fixed so that the tips of the push buttons 4 and 5 project from a through hole (not shown) formed in the front surface of the housing 11. Is fixed in the housing 11.

[0006]

In the above-mentioned conventional structure, since the relay member 3 shown in FIG. 3 is formed in a substantially L-shape, the relay member 3 lacks rigidity. Since the rotation locus of the switch pressing member 7 is not in the same plane, the relay member 3 is twisted due to the pressure applied to the push button portion 5 at the time of operating the switch, and the switch 12b cannot be pressed or is required. There were problems such as the relay member 3 and the thin portion 9 being broken by the above pressure, or the switch pressing member 7 falling off the shaft of the switch 12b.

[0007]

In order to solve the above-mentioned problems, a push-button switch device according to the present invention comprises a second relay member having a gap around a periphery of the first relay member. It is extended so as to surround it in the shape of a letter, and its tip is connected to a fixed bar to be integrally formed.

According to the structure of the present invention, the rigidity of the second relay member is increased and the connection with the fixed bar is strengthened.
Unnecessary bending deformation of the second relay member can be prevented, and breakage of the second relay member or dropping of the second switch pressing member from the shaft of the switch is prevented.
