Correction 1984. 7.28 The scope of claims for utility model registration is amended as follows. ■Claims for Utility Model Registration (1) A light source is arranged on each side of a plurality of switches arranged in parallel on a printed circuit board, and a light guide made of synthetic resin or the like is installed in each knob attached to the switch. the lower end surface of the light guide is placed in close proximity to the light source, the protrusion integrally formed with the light guide is engaged with the lever of the switch, and by pressing the knob, Activating the switch lever via the protruding piece of the light guide,
An illuminated switch characterized in that the light from the light source is guided to the upper end surface side of the knob by the light guide. (2) The lower end surface of the light guide mounted in the knob facing the light source has a substantially semicircular arc shape, and the light guide extends upward from the lower end surface to transport light from the light source in a substantially semiconical shape. and a visible part connected to this and reaching the upper end surface of the knob,
Request for registration of a utility model, characterized in that the light guide has a substantially triangular projecting piece that is latched to the upper end surface of the switch lever and is integrally formed on the side of the light transporting portion of the substantially semiconical light source. The illuminated switch according to item 1. (3) The light guide installed in the knob is prevented from being removed from the knob by a substantially semiconical light transport section of the light source and a substantially triangular protrusion integrally formed on the side thereof. An illuminated switch according to claim 1 of the utility model registration claim.

Claims

[Scope of utility model registration request]

(1) A light source is arranged on each side of a plurality of switches arranged in parallel on a printed circuit board, and a light guide made of synthetic resin or the like is installed in each knob attached to the switch. The lower end surface of the light body is disposed correspondingly close to the light source, a protrusion integrally formed with the light guide is engaged with the lever of the switch, and by pressing the knob, the protrusion of the light guide Activate the switch lever via the
An illuminated switch characterized in that the light in the light range is guided to the upper end surface side of the knob by the light guide.

(2) The lower end surface of the light guide mounted in the knob facing the light source has a substantially semicircular arc shape, and the light guide extends upward from the lower end surface to transport light from the light source in a substantially semiconical shape. and a visible portion connected to the visible portion that reaches the upper end surface of the knob, and is locked to the upper end surface of the switch lever on the side of the light conveying portion of the approximately semiconical light source of the light guide. The illuminated switch according to claim 1, wherein the substantially triangular protruding piece is integrally formed.

(3) The light guide installed in the knob is prevented from being removed from the knob by a substantially semiconical light transport section of the light source and a substantially triangular protrusion integrally formed on the side thereof. An illuminated switch according to claim 1 of the utility model registration claim.

(4) A band changeover switch and a variable resistor corresponding to each of the parallel switches are housed on the side of the printed circuit board on which the parallel switches and the light source are attached, each having a knob to which a light guide is attached. The illumination device according to claim 1, characterized in that an insulating case is fixed, and the knob of the variable resistor and the lever of the band changeover switch protrude from a hole provided in the upper surface of the case. formula switch.
