  Next, as shown in FIG. 2 for example, the push-button switch 7 and the LED are used for the rising frames 22e and 22e of the frame body 22 of the base member 2 using the locking holes 22f and 22f provided in the frames. The unit 8 is detachably attached. That is, by engaging the hook members 7b, 7b provided so as to protrude from the outer surface of the housing 7a of the push button switch 7 with the locking holes 22f, 22f, the push button switch 7 is moved to the rising frame 22e of the frame body 22, Similarly, the hook members 8b and 8b provided so as to protrude from the outer surface of the housing 8a of the LED unit 8 are engaged with the other locking holes 22f and 22f. Are attached to the rising frames 22 e and 22 e of the frame body 22.

  The push button switch 7 is provided with a push button 7c having a flat rectangular shape as shown in FIGS. 3, 5 to 7, and 11. As will be described later, the push button 7c is provided with the holding member 8d interposed therebetween. It is configured to be turned ON / OFF by one thick switch pressing portion 5f provided at the tip of the leg portions 5e and 5e of the jar 5 and the other thin switch pressing portion 5f. Although not shown, the push button switch 7 is electrically connected to the LED unit 8. In the embodiment, the reason why the holding member 8d does not cross the center of the push button 7c of the push button switch 7 is that a commercially available push button switch 7 is used, and the position of the push button 7c is more central. It is optional and recommended to come to the department.

  Inside the housing 8a of the LED unit 8, a circuit for rectifying and rectifying a 100V commercial AC power supply of a general household, not shown, and a control circuit are housed, and the holding member 8d is moved from the housing 8a to the button cap 4 And a circuit board 8g on which an LED 8c is mounted on the front surface near the tip of the holding member 8d. When the push button 7c of the button switch 7 is pushed and the push button switch 7 is turned on, for example, the LED 8c is caused to emit light by the operation of the control circuit. At that time, the light emitted from the LED 8c passes through the transparent cover 8e attached so as to cover the holding member 8d and the LED 8c, and is emitted from the light emission surface 8f (FIGS. 3 and 11) facing the button cap 4. The button cap 4 is irradiated from the inner surface through the light diffusing lens 9, and the button cap 4 is illuminated uniformly. The LED 8c in the embodiment is located at the center of the light diffusing lens 9 and the button cap 4, and this causes the button cap 4 to shine uniformly.

In the illustrated embodiment, the holding member 8d and the transparent cover 8e of the LED unit 8 cross the front of the push button 7c of the push button switch 7 and are positioned beyond the central axis of the button cap 4 or the plunger 5 or the like. 3 and 4, in order to prevent the holding member 8d and the transparent cover 8e from becoming an obstacle when the push button 7c of the push button switch 7 is pushed by the pushing operation of the plunger 5, As shown in FIG. 8 and the like, the plunger 5, the holding member 8 d, and the transparent cover 8 e are formed by forming the slot 5 d and providing the leg portions 5 e and 5 e behind the second peripheral wall portion 5 c of the plunger 5. It is configured to avoid interference with.
That is, the second peripheral wall portion 5c of the plunger 5 is formed with a plurality of legs 5e, 5e (see FIGS. 2-8, 10, 11, etc.) by the slot 5d, and between the plurality of legs, By forming the slot 5d that allows the holding member 8d and the transparent cover 8e to be accommodated, interference between the holding member 8d and the transparent cover 8e and the plunger 5 is avoided.
Further, as shown in FIGS. 6, 7, 10, and 11, there is a slight gap a, a between the inside of each leg 5 e, 5 e and both sides of the holding member 8 d or the transparent bar 8 e. Is provided so that the plunger 5 can be smoothly pressed and returned through the button cap 4 without any trouble. Then, the switch pressing portions 5f and 5f provided at the tips of the leg portions 5e and 5e divided into two branches receive pressure of the push button 7c that is exposed from both sides of the holding member 8d, particularly as shown in FIG. By configuring the portions 7d and 7d to be pressed, the pressing operation with respect to the push button 7c is surely performed regardless of the front, rear, left and right diagonal directions when the button cap 4 is pressed. It is possible to prevent squeaking and improve operability. This effect, as will be described later, when the button cap is formed in a polygonal shape such as a plane triangle shape, a quadrangular shape or a star shape, since the display area is large, there is a high possibility that a corner will be pressed. Even in such a configuration, the push button can be surely pressed.

  The light diffusing lens 9 is made of, for example, a frosted glass having a surface of a transparent plastic member subjected to fine unevenness processing, a translucent plastic member such as milky white, and the like. The light emitted through the light emitting surface 8f is diffused so that the entire outer peripheral surface of the button cap 4 can be illuminated. It is also possible to enhance the design effect by drawing a pattern or the like on the button cap 4.

  When the user presses the button cap 4 when entering the toilet, for example, the plunger 5 moves backward against the elasticity of the elastic means 6 as shown in FIGS. The pressure receiving portions 7d and 7d of the push button 7c of the push button switch 7 are pushed and pushed by the switch pushing portions 5f and 5f of 5e and 5e, the ON operation of the push button switch 7 is performed, and the LED 8c is lit. At this time, the toilet room light may be turned on at the same time. Further, at that time, even if the user releases the button cap 4 and the button cap 4 and the plunger 5 return to the original positions as shown in FIGS. 7 ON state is maintained. When the user finishes using the toilet and presses the button cap 4 again when leaving the room, the push button 7c of the push button switch 7 that has already returned to the original position is pressed by the switches of the leg portions 5e and 5e of the plunger 5. Since the LED lighting circuit is turned off by being pushed by the parts 5f and 5f, the LED is turned off. When the user releases his / her hand from the button cap 4, the button cap 4 and the plunger 5 are returned to their original positions as shown in FIGS. At this time, the toilet room light may be turned off at the same time.

  The configuration of the present invention is not limited to the above embodiment. For example, since the area occupied by the button cap 4 with respect to the decorative cover 10 is large, the shape of the button cap 4 is bowl-shaped. Besides, since the planar shape can be various shapes such as a quadrangle, a triangle, a heart shape, a star shape, etc., the degree of freedom of design is increased and the interior effect can be enhanced. Further, the function of the push button switch 7 can not only simply turn on the LED but also turn on the room light at the same time. Accordingly, the present invention encompasses all modified embodiments that fall within the scope of the claims.

  Since the present invention is configured as described above, the wall-embedded illuminated pushbutton switch according to the present invention has a high degree of freedom in design and is equipped with interior characteristics, so that it is a general house with a commercial AC power supply. For example, in a building such as a condominium, department store, etc., it is preferably used as an indicator that indicates whether a room is in use or is in use by being attached to a wall next to the entrance / exit of a conference room, reception room, consultation room, private room, etc. Is.
