A plurality of wirings on the printed circuit board are pressed and electrically connected. Moreover, the flexible printed circuit board can be reliably held on the holder member H1 by the engagement structure between the first positioning portion 12R and the second positioning portion 19F and the locking structure between the claw portion 52n and the engagement portion 51h. As a result, it is possible to easily connect wires while having a simple structure as compared with a structure in which a plurality of harnesses 923 are connected one by one as in the conventional example.

  Further, since the first positioning part 12R is the convex part 12t and the second positioning part 19F is the through hole F9h, the flexible structure of the wiring base material F9 can be obtained with a simple structure simply by inserting the convex part 12t into the through hole F9h. The printed board can be held by the fixing member R2. Moreover, when the flexible printed circuit board and the plate-like portion R12 of the fixing member R2 are inserted and press-fitted into the opening 51k of the holder member H1, the through hole F9h inserted into the convex portion 12t is detached from the convex portion 12t. It has a difficult structure. As a result, the flexible printed board can be securely held by the holder member H1 by the fixing member R2, and the plurality of electrodes B9e of the base base material B9 and the plurality of wirings of the flexible printed board being the wiring base material F9 are surely secured. It becomes possible to conduct.

  In addition, since the flexible printed circuit board is inserted into the slit portion 12s of the plate-like portion R12 and folded back at the slit portion 12s, the first positioning portion 12R and the second positioning portion 19F are engaged. It becomes possible to hold the flexible printed board of the wiring base material F9 more securely by the fixing member R2. Thus, the flexible printed board can be more securely held by the holder member H1 by the fixing member R2, and the plurality of electrodes B9e of the base base material B9 and the plurality of wirings of the flexible printed board being the wiring base material F9 are connected. It becomes possible to conduct more reliably.

  Further, the claw portion 52n that engages with the engaging portion 51h of the holder member H1 is formed at a position facing the side end portion 12w on the insertion direction side of the plate-like portion R12. At the back, the fixing member R2 is engaged with and fixed to the holder member H1. For this reason, since the movement of the fixing member R2 in the width direction is regulated in proportion to the depth, the backlash of the fixing member R2 can be suppressed. Thereby, the flexible printed circuit board which is the wiring base material F9 can be more reliably held on the holder member H1 by the fixing member R2, and the plurality of electrodes B9e and the plurality of wirings can be more reliably conducted. It becomes possible.

<Modification 1>
In the first embodiment, the flexible printed circuit board (wiring base material F9) and the base base material B9 bent to the bottom surface side (the Y2 side surface side shown in FIGS. 8 and 9) of the plate-like portion R12 of the fixing member R2. As shown in FIG. 11, the convex portion C12t, which is the first positioning portion, is placed on the upper surface side of the plate-like portion CR12 of the fixing member CR2 (the surface side on the Y1 side shown in FIGS. 8 and 9). It is good also as a structure which press-contacts the convex part C12t and the ceiling surface of the accommodating part CH51, and press-contacts a flexible printed circuit board (wiring base material F9) and the base base material B9.

<Modification 2>

Thereby, since the press-contact part of the some electrode B9e of the base base material B9 and the some wiring of a flexible printed circuit board (wiring base material F9) can be hold | suppressed over the whole surface, several electrode B9e and several wiring and Can be conducted more reliably.

<Modification 3>
In the first embodiment, a flexible printed circuit board is used as the base substrate B9. However, as shown in FIG. 13, a plurality of wires are directly provided on the surface of the holder member CH1, and the surface of the holder member CH1 is used as a base. You may make it the structure used as the base material CB9. In order to directly provide a plurality of wirings on the surface of the holder member CH1, a so-called three-dimensional injection molded circuit component (MID, Molded Interconnect Device), which is performed using a method combining laser and electroless copper plating, or the like is used. With technology, it is possible to easily form a three-dimensional wiring (conductor circuit) on the surface of an injection molded product. Thereby, it is possible to reduce the labor and difficulty of laying the base substrate B9 inside the operation knob N301 of the Stoke switch device N510 in a narrow space. Further, the positioning of the plurality of electrodes B9e of the base substrate CB9 and the plurality of wirings of the flexible printed circuit board (wiring substrate F9) is performed by stacking the fixing member R2 and the flexible printed circuit board (wiring substrate F9) on the holder member. Simply inserting it into the opening 51k of H1, it can be done easily and reliably.
