Problems solved by technology

On the other hand, if the diameters of the guide pin and the guide hole are too close, the button will not move smoothly if the direction of the pressing operation is different from the direction of movement of the guide pin.
From this point of view, in the structure described in this patent document, although it is described that a cylindrical guide member for allowing the pin to slide well is inserted on the base plate, the deviation between the operating direction and the moving direction of the pin is difficult. How to reliably achieve smooth motion is not well documented

Abstract

The present invention provides a luminous switch structure with high durability and excellent reliability, and a push button. The luminous switch structure comprises the following components: a substrate (10) which is provided with an insertion hole (11); a switch unit (20) which is fixed on the substrate (10) and is provided with a driven part (23) that is set to reciprocate for the action of switch; an illumination part (LED30); and a push button (40). The push button (40) comprises the following components: a light penetration part (522) which is provided at the outer end and forms a space for accommodating the illumination part and causes the light of the illumination part to pass through; a fixing paw (60) which extends from one side part (511a) of the push button (40) and passes through the insertion hole (11) for fixing with the substrate; a clamping projection (70) which clamps the substrate (10) between the front end of the fixing paw (60); and combination parts (80, 80A) which are provided at the other side part (511c) of the push button (40) and are combined with the driven part (23) of the switch unit (20).

Description

technical field [0001] The present invention relates to an illuminated switch structure applied to various electronic devices such as electronic keyboard instruments, hybrid speakers, and the like, and a button used for the structure. Background technique [0002] Illuminated switch structures are often used in various electronic devices such as electronic keyboard instruments and hybrid speakers. This switch structure performs switching operations such as opening and closing each time the user presses the button with a finger. In order to clearly display the switch state, a light-emitting part is arranged inside the button, and the light-emitting part switches on and off each time the switch state changes. Therefore, in the illuminated switch structure, the button is provided on the substrate so as to cover the switch unit and the light emitting part, and can move up and down. [0003] Various embodiments have been proposed as conventional light-emitting switch structures...
