In this manner, since the element holding portion 10c of the rotating body 10 holds the base 13a of the light emitting diode, the light of the light emitting diode is not obscured by the holder portion, and much light can be irradiated. Therefore, the dimming efficiency can be improved.

In addition, the movable contact 11 is arrange | positioned at the lower surface side of the pedestal part 10b of the rotating body 10 at this time, and the terminal 13c of the light control member 13 is inserted in the hole 10d and not bent. Since lowering also makes it possible to conduct the other end of the movable contact 11, bending processing of the terminal 13c of the light control member 13 becomes unnecessary, while improving the assemblability and reducing the cost. Will be able to.

In addition, since the movable contact 11 can be held directly on the rotating body 10 by soldering with the terminal 13c on the lower surface side of the pedestal portion 10b, a support for supporting the movable contact as in the prior art becomes unnecessary. The part score can be reduced.

The mounting member 14 made of a metal plate includes a ring-shaped pressing portion 14a, a plurality of relatively short first mounting portions 14b bent downward from the outer peripheral portion of the pressing portion 14a, and the pressing portion 14a. Has a plurality of relatively long second mounting portions 14c that are bent downward from the outer circumferential portion thereof.

The pressing member 14a is mounted on the stepped portion 10a of the rotating body 10 by the mounting member 14, and the first mounting portion 14b is attached to the outer side of the rotating body 10 and the housing 7. When the front end of the first mounting portion 14b is bent to the lower surface side of the housing 7 in the positioned state, the rotating body 10 and the housing 7 are integrated to form the light control unit S.

And the engaging portion 15d formed inside the leg portion 15c and the cylindrical engaging portion 15e formed in the leg portion 15c at a position corresponding to the pedestal portion 10b.

When the operation part 6 is inserted into the cylindrical leg part 15c, and this operation member 15 is snap-fastened so that the locking part 15d may be caught by the mounting click part 6b, it will be attached to the operation member 15. The operation part 6 is rotated by this.

In addition, when the operation member 15 is mounted, the cylindrical engaging portion 15e includes the pedestal portion 10b constituting the holder portion, the element holding portion 10c, and the light emitting portion 13b of the dimming member 13. The inner surface of the engaging portion 15e engages with the circumferential end face of the pedestal portion 10b, and as a result, the engaging portion 15e is rotated by the rotation of the operating member 15. ) Hangs the pedestal portion 10b to rotate the rotating body 10.

In addition, in the side part or upper part located in the vicinity of the light emission part 13b, the operation member 15 is formed with the resin which is transparent or translucent translucent, and light can be seen visually from the part, The other part is made of an opaque resin such as black to eliminate light leakage.

Although not shown here, the illuminating rotary electric component having such a configuration is mounted on a printed board having a conductive pattern, and the lead terminals 4b and 9 are not shown, but the lower case 2 and the upper case 3 are not shown. The leg part formed in the attachment plate which consists of metal which couple | bonds) is soldered to the printed board, and mounting and wiring are performed.

Next, when the operation | movement of the light-type rotary electric component which has such a structure is demonstrated, first, the operation member 15 will rotate. Then, the rotating plate 5 rotates via the operation part 6 to switch contacts, whereby rotation detection (output of an electrical signal) is performed, and the rotating body 10 together with the operating member 15. ) And the light control member ((LED) 13) rotate.

And since the pair of movable contacts 11 rotate in the state which always contacted the fixed contact 8, the light control member ((LED) 13) rotates in the lighted state, As a result, one light control member By (LED 13), the rotational position of the operation member 15 is displayed by dimming. In addition, rotation of the operation member 15 is performed until the stopper part 10e is engaged with the stopper part 7d, and when it is rotated in the opposite direction, the stopper is peeled off and the operation member 15 can be rotated.
