When the swing of the knob 110 is released, the rotating body 60 automatically returns to the original neutral position by the elastic return force of the torsion coil spring 200.

  On the other hand, when the knob operation unit 113 of the knob 110 is pressed directly downward, that is, in the direction of the rotation axis L1 of the rotary electronic component 10 from the neutral position of the knob 110, the entire rotary electronic component 10 including the movable object 80 is obtained. It moves in the pressing direction (parallel movement), and the pressing portion 91 of the movable object 80 shown in FIG. 3 turns on the first switch 165. When the knob operation unit 113 is further pressed downward, the switch base 180 is lowered together with the rotary electronic component 10, and the pressing unit 191 of the mounting member 190 turns on the second switch 171. When the pressure on the knob operation unit 113 is released, the second switch 171 and the first switch 165 are turned off in this order by the elastic return force of the two movable contact plates 163 and 169, and the knob 110 is restored to the original state. Automatically returns to the neutral position.

  By the way, when the knob 110 is pressed down in the neutral position as described above, the pair of locking portions 117 provided on the knob 110 is paired with the pair of cases provided on the case 130 as indicated by arrows in FIG. The push switch mechanism 150 can be turned on and off as described above by being inserted into the insertion portion 143. On the other hand, when the knob 110 is rotated from the neutral position and the knob 110 is pressed from the rotated position toward the rotation axis L1, the knob 110 is moved to the knob 110 when the entire rotary electronic component 10 is lowered as shown in FIG. The pair of locking portions 117 provided is not inserted into the pair of insertion portions 143 provided in the case 130, but abuts against the upper surface 133 of the case 130 around the insertion portion 143. Therefore, the rotary electronic component 10 cannot be lowered, The push switch mechanism 150 cannot be turned on / off. In the present embodiment, the push-type switch mechanism 150 is configured to be operated only at a predetermined position, that is, at the neutral position. The structure of the latching | locking part 117 and the insertion part 143 which operate the press-type switch mechanism 150 only in a position may be sufficient.

  The knob 110 of the rotary electronic component 1 with the pressing switch mechanism is formed long in the direction of the rotation axis L1. Therefore, it is only necessary to press the position of the knob 110 directly above the rotating body 60. However, if a position shifted from the position in the direction of the rotation axis L1 (front and back) is pressed, the knob 100 tilts and descends without being translated. There is a fear. Therefore, in this embodiment, when the knob 100 is slightly inclined, the rocking prevention part 83 or the rocking prevention part 121 shown in FIG. This prevents the knob 100 from tilting so that the knob 100 does not tilt. It should be noted that the swing prevention portion protruding from the lower surface of the knob 100 may be arranged close to the upper surface of the movable object 80 to obtain the above-described action.

  That is, as shown in FIG. 3, the rotary electronic component 1 with a push-type switch mechanism is arranged (stored) so that the rotary electronic component 10 and the rotary electronic component 10 can be moved in the vertical direction of the rotary electronic component 10. In addition, a case 130 in which an opening 135 is provided to project the upper portion of the rotary electronic component 10 to the upper surface side, and is installed on the lower surface side of the rotary electronic component 10 and is turned on and off by the vertical movement of the rotary electronic component 10. The rotary electronic component 10 is further operated by rotating the rotary electronic component 10 at a predetermined rotational position (neutral position in this embodiment). A knob 110 for operating the pressing switch mechanism 150 by moving the rotating electronic component 10 by pressing it toward the rotation axis L1 of the ten. Ri with push type switch mechanism with a rotary electronic component 1 is disclosed a.

  In addition, the rotary electronic component 1 with a push switch mechanism is inserted to prevent the knob 110 from being pressed when the knob 110 is in a rotational position other than the predetermined rotational position (neutral position in this embodiment). A configuration in which a knob pressing prevention mechanism including a portion 143 and a locking portion 117 is provided is disclosed. The locking portion 117 and the insertion portion 143 constituting the knob pressing prevention mechanism are configured so that the locking portion 117 is inserted into the insertion portion 143 only when the knob 110 is pressed at the predetermined rotational position (neutral position in this embodiment). It is formed in the shape inserted in. The rotary electronic component 1 includes a first flexible circuit board 21 that extracts an electrical output, while the pressing switch mechanism 150 includes a second flexible circuit board 160 that extracts an electrical output. The first drawing portion 25 drawn to the outside of the rotary electronic component 10 of 21 and the second drawing portion 173 drawn to the outside of the pressing switch mechanism 150 of the second flexible circuit board 160 are connected means (this embodiment). The first drawing portion 25 and the second drawing portion 173 are overlapped between the base 90 and the movable object 80 and then connected by pressure contact means 93). A configuration is disclosed.

  FIG. 8 is a schematic sectional side view of a rotary electronic component 1-2 with a push switch mechanism according to another embodiment of the present invention. FIG. 9 is an exploded perspective view (corresponding to FIG. 4) of a portion of the rotary electronic component main body 20-2 used for the rotary electronic component 1-2 with the pressing switch mechanism.

Attached. Note that matters other than those described below are the same as those in the embodiment shown in FIGS.

  The rotary electronic component 1-2 with the push-type switch mechanism is different from the rotary electronic component 1 with the push-type switch mechanism in that the rotary electronic component 1 with the push-type switch mechanism 2 is provided on the knob 110. The locking portion 117 is omitted, and instead, the protruding portion 75 protrudes forward from the lower part of the surface of the rotating member 61 of the rotating body 61 on the side where the elastic member storing portion 65 is provided, and downwards ( A rectangular columnar locking portion 76 protruding in the upper surface direction of the case 130 is provided, and the lower portion of the presser member 89 is linearly cut out so that the locking portion 76 does not abut, and the swing prevention portion 83 is provided. Only the points omitted. The locking portion 76 is formed in a dimensional shape in which the inner diameter dimension of the insertion portion 143 and the outer diameter dimension thereof are substantially the same so that the locking portion 76 can be inserted exactly into the insertion portion 143 of the case 130. The locking portion 76 and the insertion portion 143 provided in the case 130 constitute a knob pressing prevention mechanism.

  And in this rotary electronic component 1-2 with a push type switch mechanism, if the knob operation part 113 of the knob 110 is pressed from its neutral position downward, that is, toward the rotation axis L1, the same as in the above embodiment. The first and second switches 165 and 171 are turned on / off. At this time, the locking portion 76 of the rotating body 60 is inserted into the insertion portion 143 provided in the case 130. On the other hand, when the knob 110 is rotated from the neutral position and the knob 110 is pressed toward the rotation axis L1 from the rotated position, the locking portion 76 of the rotating body 60 is inserted into the insertion portion 143 provided in the case 130. Therefore, it contacts the upper surface 133 of the case 130 around the insertion portion 143, so that the rotary electronic component 10 cannot be lowered, and the push switch mechanism 150 cannot be turned on / off.
