A plane 9a is formed. In addition, the inner bottom portion 7 has rotation detection fixed contacts 10 and 11 formed along the rotation direction of the operating body 2 and the depth side in the pushing direction with respect to the fixed contacts 10 and 11 (lower side in FIG. 6). Fixed contact 12 for pushing detection located on the opposite side of the fixed contact 12 across the support shaft 9 and fixed for common formed along the rotation direction and pushing direction of the operating body 2 The contact 13 is integrally formed. These fixed contacts 10 to 13 protrude laterally from the wall 8 of the wafer 1 as external terminals 10 a to 13 a, respectively. The front side of the wall portion 8 in the pushing direction is formed in an arc shape with the support shaft 9 as a center, and a step portion 14 is formed in the arc-shaped portion. The step portion 14 defines a rotation range of the operating body 2, and a concave portion 15 that is recessed toward the inner bottom portion 7 is formed at the center portion of the step portion 14. Further, a mounting hole 16 is formed on the depth side (the lower side in FIG. 6) of the wall portion 8 in the pushing direction.

  The operation body 2 is integrally formed in a symmetrical shape, and as shown in FIG. 4, a base portion 17 disposed in a storage space (a portion surrounded by the inner bottom portion 7 and the wall portion 8) of the wafer 1. And an operating portion 18 protruding from the wafer 1 and a connecting portion 19 for connecting the base portion 17 and the operating portion 18, and the connecting portion 19 is inserted through the stepped portion 14 of the wafer 1. A cylindrical boss 21 is erected at the center of the base portion 17, and a long hole 20 formed in the boss 21 extends in the pushing direction of the operating body 2, and the support shaft 9 is inserted into the long hole 20. ing. Further, an annular groove 17a is formed around the long hole 20, and a pair of engagement grooves 22, 23 are formed obliquely upward from the annular groove 17a. As shown in FIG. 1, the winding portion 4a of the torsion coil spring 4 is wound around the boss 21 and positioned in the annular groove 17a, and both the arm portions 4b and 4c are engaged grooves 22 and 23, respectively. Passed through and engaged with the engaging steps 8a and 8b of the wafer 1. Further, a plane 20a perpendicular to the longitudinal direction of the long hole 20 is formed on the near side in the pushing direction of the long hole 20, and when the operating body 2 shown in FIG. The plane 20a of the long hole 20 and the plane 9a of the support shaft 9 are kept apart from each other during the rotation operation shown in the figure. On the other hand, the plane 20a and the plane 9a are in contact with each other when the operating body 2 shown in FIG. Touch.

  The operation portion 18 is formed in an arc shape with the base portion 17 as the center, and a protrusion 24 is formed inside the center of the operation portion 18. When the operating body 2 shown in FIG. 2 is rotated, the projection 24 moves outside the stepped portion 14 of the wafer 1. However, when the operating body 2 shown in FIG. The inside of the recess 15 is moved.

  The slider 3 has a pair of attachment portions 25 and 26 attached to the lower surface of the base portion 17 and a pair of sliding contact portions 27 and 28 formed between the attachment portions 25 and 26, which are integrally formed. In general, it is configured in a symmetrical shape. Movable contacts 27a and 28a projecting downward are formed at the centers of the sliding contact portions 27 and 28, respectively, and one movable contact 28a is always in contact with the common fixed contact 13. 1 to 3, in order to facilitate the explanation of the relative positions of the movable contacts 27a and 28a, the movable contacts 27a and 28a are indicated by hatched ellipses and circles, respectively, and the fixed contact 10 To 13 and external terminals 10a to 13a are indicated by two-dot chain lines, respectively.

  A plurality of locking portions 29 are formed in the lid member 6, and these locking portions 29 are inserted along the wall portion 8 of the wafer 1, and the tip thereof is bent and locked to the lower surface of the wafer 1. Accordingly, as shown in FIG. 5, the upper opening 1 a of the wafer 1 is covered with the lid member 6.

  In the above embodiment, both arms 4b and 4c of the torsion coil spring 4 are engaged with the engaging step portions 8a and 8b of the wafer 1 when the operating body 2 shown in FIG. Since the winding portion 4 a is wound around the boss 21 of the operating body 2, a return force from the torsion coil spring 4 to the center position is applied to the operating body 2. At this time, the protrusion 24 of the operation body 2 faces the concave portion 15 of the wafer 1, and the plane 20 a of the long hole 20 of the operation body 2 and the plane 9 a of the support shaft 9 are separated from each other. In addition, the movable contact 28a of the slider 3 is always in contact with the common fixed contact 13, but the other movable contact 27a is not in contact with any of the other fixed contacts 10-12. And the push switch are both off.

  When the operation portion 18 of the operating body 2 is rotated counterclockwise in this state, the slider 3 also rotates around the support shaft 9 in conjunction with the operating body 2 as shown in FIG. Since the movable contact 27a of the child 3 comes into contact with one fixed contact 11 for detecting rotation, the external terminal 11a and the common external terminal 13a are brought into conduction, and only the rotary switch is turned on and the first electric signal is transmitted. Is output. At this time, one arm portion 4 b of the torsion coil spring 4 is locked to the engaging step portion 8 a of the wafer 1, while the other arm portion 4 c is held by the end portion of the engaging groove 23 of the operating body 2. Since the arm portions 4b and 4c are compressed in the closing direction by being pressed in the rotation direction and separated from the engaging step portion 8b, a restoring force to the center position is applied to the operating body 2. When the operating unit 18 is released, the operating body 2 rotates clockwise by the urging force of the torsion coil spring 4 and automatically returns to the center position shown in FIG. 1, and the movable contact 27a is fixed for detecting rotation. Since the switch 11 is away from the contact 11, the rotary switch is turned off again. Since the protrusion 24 moves away from the recess 15 and moves outside the stepped portion 14 during the rotation operation of the operation body 2, even if a force in the pushing direction is mistakenly applied during the rotation operation of the operation body 2, the protrusion 24. However, since the operating body 2 cannot be pushed in contact with the stepped portion 14, an erroneous operation of the operating body 2 can be prevented.

  Similarly, when the operating body 2 is rotated clockwise, the movable contact 28a of the slider 3 is always in contact with the common fixed contact 13, and the other movable contact 27a is the other fixed contact for detecting rotation. 10, the external terminal 10 a and the common external terminal 13 a are brought into conduction, and only the rotary switch is turned on to output the first electric signal.

  When the operating unit 18 is pushed in the direction of the wafer 1 from the non-operating state of the operating body 2 shown in FIG. 1, the operating body 2 and the slider 3 are moved in the longitudinal direction of the long hole 20 as shown in FIG. Move together. Along with this, the click plate 5 is pressed against the base portion 17 and is buckled and deformed, so that a feeling of clicking (moderation) is generated and the movable contact 27a of the slider 3 contacts the fixed contact 12 for detecting indentation. Therefore, the external terminal 12a and the common external terminal 13a are brought into conduction, and only the push switch is turned on, and the second electric signal is output. At this time, both arms 4b and 4c of the torsion coil spring 4 are locked to the engaging step portions 8a and 8b of the wafer 1, but the winding portion 4a is pushed in by the boss 21 of the operating body 2 in the pushing direction. Therefore, the return force to the center position is applied to the operating body 2 by compressing the arms 4b and 4c in the closing direction. When the operating portion 18 is released, the operating body 2 is raised by the urging force of the torsion coil spring 4 and automatically returns to the center position shown in FIG. 1, and the movable contact 27a is moved from the fixed contact 12 for detecting indentation. The push switch is turned off again. In addition, since the protrusion 24 moves inside the recess 15 during the pushing operation of the operating body 2, even if a force in the rotation direction is accidentally applied during the pushing operation of the operating body 2, the protrusion 24 is applied to the wall surface of the recess 15. Since the operating body 2 cannot be rotated by contact, an erroneous operation of the operating body 2 can be prevented also in this case.
