Referring first to FIG. 1, the illuminated push-button switch of the illustrated embodiment comprises a switch body 1 and a slider 2, and the switch body 1 comprises a case 4 and a metal frame 3; Multiple terminals 1 protruding from the middle and lower surfaces
0 is connected to a contact (not shown) built in the case 4. As shown in FIGS. 1 and 5,
The frame 3 is provided on the case 4 so as to cover the front surface of the case 4, and is caulked and fixed to the case 4 at a position 3 a. As shown in FIG. 3, the frame 3 has projecting surfaces projecting to both sides of the front surface of the case, and the switch body 1 is provided on both projecting surfaces.
A mounting hole 3b for mounting the device to a panel or the like of the device is formed.

As can be seen from FIGS. 1 and 4, a part of the slider 2 is inserted into the frame 3 from the front opening 4a of the case 4.
Projecting to the outside through a hole 3c formed in the hole. The slider 2 has a shaft 2a and a slider tip 2b fixed to the protruding end of the shaft 2a. A push button 6 is fixed to the front surface of the slider tip 2b. Is a light emitter for illuminating the push button unit 6, for example, an LED
(Not shown). The switch body 1 is configured such that when the slider 2 is pressed inward of the case 4, the open / close state of the contact inside the case 4 is switched. Since this contact switching structure itself is well known, a detailed description thereof will be omitted here.

On the slider shaft portion 2a between the slider tip portion 2b and the frame 3 of the switch body 1, a returning member for urging the slider 2 in a projecting direction, that is, in a direction opposite to the pressing operation direction. A coil spring 5 is mounted.

Referring to FIG. 1, FIG. 2 (A), FIG. 4 and FIG. 5, the illuminated push button switch serves as a wiring structure for energizing the luminous body. A pair of metal terminals 8a, 8a formed integrally with the wafer 7; and a pair of flexible conductors formed integrally with the slider tip 2b and connected to the electrodes of the light emitter in the slider tip. Pair of metal bands 8, 8 as
The terminals 8a, 8b and the metal bands 8, 8 are integrally formed by punching a metal tape material. The metal bands 8, 8 are arranged on both sides of the slider 2 and are curved in an arc shape. The terminals 8a, 8a are formed in an arc-shaped or U-shaped cross section in order to obtain a predetermined rigidity.
