A method for assembling the above-described components will be described.
First, after a rotor 50 having a rotating contact plate 40 fixed by caulking to the bottom surface is fitted in the recess 21 of the base 20 so as to be rotatable, a return spring 60 is fitted into the rotor 50 and the return spring is also fitted. Both end portions 61 and 62 of the 60 are respectively engaged with the notch portions 52 for engagement of the rotor 50. At this time, the common movable contact pieces 42, 43 and the first, second and third movable contact pieces 44, 45, 46 of the rotating contact plate 40 are in contact with the bottom surface of the recess 21 of the base 20.

  Then, the engagement hole 73 of the cover 70 is engaged and attached to the locking claw portion 25 of the base 20. As a result, the rod-like protrusions 75 and 75 of the cover 70 are engaged with both end portions 61 and 62 of the return spring 60, respectively. Further, the common movable contact pieces 42 and 43 and the first, second and third movable contact pieces 44, 45 and 46 of the rotating contact plate 40 are all in pressure contact with the bottom surface of the recess 21 of the base 20. Further, since the rotor 50 is biased upward by the spring force of the common movable contact pieces 42, 43 and the first, second and third movable contact pieces 44, 45, 46, the annular rib 51 of the rotor 50 is The edge is in pressure contact with the ceiling surface of the cover 70.

  Further, after the operation spring 80 is assembled to the shaft portion 72 of the cover 70, the shaft hole 91 of the operation lever 90 is fitted to the shaft portion 27 of the base 20, and the operation arm portion 94 is operated to operate the base 20. Fits into the hole 28. For this reason, when the operation arm portion 94 pushes up the common movable contact piece 42, the common movable contact piece 42 is separated from the bottom surface of the recess 21 of the base 20.

Next, the base 20 is positioned on the upper surface of the case 10, and the notch 36 of the position restricting plate 35 to which the terminal portions 30 b to 34 b are attached is engaged with the positioning rib 14 of the cylindrical socket portion 13. By assembling the fixing elastic claw portion 11 of the case 10 to the 20 fixing step portions 24, the assembly operation is completed.

The other common movable contact piece 43 is in pressure contact with the common fixed contact portion 32a located on the bottom surface of the base 20, and the first movable contact piece 44 is in pressure contact with the first fixed contact portion 30a. The second and third movable contact pieces 45 and 46 are in pressure contact with the bottom surface of the base 20, but are not in contact with the second and third fixed contact portions 33a and 34a . However, since the common fixed contact terminal 32 is a dummy terminal, no output signal is output.

  Then, as shown in FIG. 24, when the operation lever 90 is pushed down, the operation spring 80 is compressed, the operation arm portion 94 is lowered and separated from the common movable contact piece 42, and the common movable contact piece 42 is shared. Press contact with the fixed contact 31a. For this reason, the first fixed contact terminal 30 and the common fixed contact terminal 31 are conducted through the rotating contact plate 40, and a signal indicating that the operation lever 90 is pressed is output.

  Further, as shown in FIG. 25, when the rotor 50 is rotated to one side from the neutral position where the operation lever 90 is kept pressed down, the second movable contact piece 45 comes into contact with the second fixed contact portion 33a. A signal indicating that the rotor 50 has been turned to one side is output. When the rotational force with respect to the rotor 50 is released, the rotor 50 returns to the original neutral position by the spring force of the return spring 60.

  Further, as shown in FIG. 26, when the rotor 50 is rotated from the neutral position where the operation lever 90 is kept pressed down to the other side, the third movable contact piece 46 comes into contact with the third fixed contact portion 34a. A signal indicating that the rotor 50 has been rotated to the other side is output. When the rotational force with respect to the rotor 50 is released, the rotor 50 returns to the original neutral position by the spring force of the return spring 60.

  Next, when the pressing force on the operation lever 90 is released, the operation lever 90 is pushed up by the spring force of the operation spring 80, and the operation arm portion 94 of the operation lever 90 pushes up the common movable contact piece 42, thereby returning to the original position. Return to.

As shown in FIGS. 27 to 32, the third embodiment is substantially the same as the first embodiment described above, and is different from the first embodiment in that the operation lever 90 is not interposed. The point is that the rotor 50 is pushed down directly at 70.
As shown in FIG. 30, the cover 70 has a substantially gate-like shape that can cover the base 20, and has a protrusion 76 protruding from the center upper surface thereof, and the other is the first embodiment described above. Therefore, the same parts are denoted by the same reference numerals and the description thereof is omitted.

  According to this embodiment, since the rotor 50 can be pushed down directly by pushing down the cover 70, there is an advantage that a switch that operates quickly and has excellent responsiveness can be obtained.

  In the third embodiment, it is needless to say that the cover 70 may be operated via the operation lever as well as the above-described embodiment, instead of being pushed down directly. Conversely, in the first and second embodiments, not only the cover 70 is operated via the operation lever 90, but the cover 70 may be directly operated.

  Needless to say, the present invention is not limited to the above-described switch, but may be applied to other switches. Further, the switch according to the present invention is not limited to a passenger car, and may be applied to other devices.
