Description

  The present invention relates to a push button switch provided on an operation panel of an elevator.

  Conventionally, this type of push button switch has a structure in which a pressing portion is formed of a light guide plate, and an LED is arranged on the back side thereof to shine the light guide plate, and it is necessary to arrange the LED according to the illumination range. For this reason, the number of LEDs is large, and a large depth dimension is necessary to diffuse light.

  Some pushbutton switches of this type use two types of light sources to double-illuminate the light guide plate. In that case, however, a partition box, light-shielding printing on the light diffusion plate, etc. are required, and the structure is complicated. There was a problem that.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a push button switch for an elevator that has a small number of parts, a simple structure, and a small depth dimension and is thin.

In order to achieve the above object, the present invention provides a pressing portion formed of a light guide plate, a central embossed portion provided on either the surface or the back surface of the pressing portion, and the back surface or the surface of the pressing portion. The first embossing part disposed on the other side of the pressing part and the side surface of the pressing part, the first light source illuminating toward the central embossing part, and the side surface of the pressing part placed so you, the second light source that illuminates toward the peripheral embossed portion, provided with either one of the first light source or the second light source is brightest said central embossed portion The first light source and the second light source are arranged so as to be displaced in the pressing direction so that either one of them illuminates the peripheral textured portion most brightly. that the light of the second light source does not interfere It is a push button switch of the elevator and butterflies.

  According to the present invention, since each light source is disposed so as to face the side surface of the pressing portion, the depth dimension can be reduced and the thickness can be reduced. Further, since each light source illuminates the central textured portion and the peripheral textured portion from the side, since the illumination range of each light source is wide, the number of light sources can be reduced. Further, since the light from the first light source and the second light source do not interfere with each other, light shielding printing or the like on the partition box or the light diffusion portion is unnecessary. Therefore, the number of parts can be reduced and the structure is simplified.
