Problems solved by technology
However, this additionally requires a holding mechanism with a frame, which complicates the structure and at the same time increases the size and production costs of the illuminated switch
Furthermore, in the light-emitting switch structure disclosed in the third prior art document, since the operating portion is long and narrow, the operation of the light-emitting switch based on the switch operating position is unstable, which reduces the operability of the switch

Embodiment Construction
[0051] The invention will now be described in detail with reference to the accompanying drawings showing preferred embodiments.
[0052] figure 1 is a perspective view showing the appearance of a light-emitting switch having the light-emitting switch structure according to the first embodiment of the present invention. The light switch LSW is composed of a switch unit US, a button unit UB, and an LED (Light Emitting Diode) 40 . The button unit UB is operated to actuate the switch unit US, and is composed of the button main body 10 , the diffuser plate 20 and the lamp housing 30 . The light-emitting switch LSW is suitable as a switch widely used in electrical devices and equipment such as mixers, whose on / off operation is recognized by turning on / off its light emitter.
[0053] FIG. 2 is an exploded perspective view of the light emitting switch LSW. 3A to 3C show details of the structure of the light-emitting switch LSW, wherein FIG. 3A is a top view of the light-emitting sw...

The invention discloses a luminous switch structure, which can ensure excellent visibility and operability of the luminous switch, and at the same time, the luminous switch has compact size, reduced cost and simple structure. A plurality of guide holes are formed in the substrate. The switch unit and the LEDs provided on the substrate are positioned adjacent to each other. The switch unit has a driven portion driven to reciprocate. A button unit formed of a diffuser plate and a button body, the diffuser plate and the button body being stacked on the lamp housing. A plurality of guide pins extend from the lamp housing and are fitted into corresponding guide holes. The lamp housing has a mounting portion in which a mounting hole is formed, and the head portion of the driven part of the switch unit is mounted and held in the mounting hole. The reciprocating action is performed in a partially interlocked manner. The guide pins slide in the corresponding guide holes, thereby guiding the reciprocating action of the button unit.
Description
technical field [0001] The present invention relates to a light-emitting switch structure suitable for various electronic devices and equipment such as a mixer, and also relates to a button unit for a light-emitting switch. Background technique [0002] In general, illuminated switches such as a push type are widely used as operating elements in mixers, electronic musical instruments, and other electronic devices and equipment. Push-type illuminated switches include types that have a press portion formed of a transparent member and an associated light-emitting portion formed of an LED (Light Emitting Diode), etc., which can make the press portion appear more attractive than a light-emitting switch having a press portion formed of rubber or other substances. The higher quality external characteristics of the pressing part. When the pressing part is operated, the associated light emitting part emits light which can be seen through the transparent pressing part. [0003] In t...
