Since the switch 80 is disposed and the pressing switch 78 is disposed at a position facing the pressing portion 95 provided on the lower surface of the mounting base 90 on the second circuit board portion 73, the central switch 80 and the pressing switch 78 are mounted. Since it can arrange | position so that it may be settled in the same plane under the base 90, the structure of the multifunctional electronic component 1 can be simplified and the thickness reduction can be achieved.

  Furthermore, in this multifunctional electronic component 1, the first circuit board portion 71 and the second circuit board portion 73 are made to be a flexible circuit board 70 that is integrally connected via a connecting arm 72, so that the sliding contact pattern 75 Since the pressing switch 78 and the central switch 80 are provided on the same flexible circuit board 70, the number of components of the multifunctional electronic component 1 can be reduced. Further, the sliding contact pattern 75 is installed on the first circuit board portion 71 and the central switch 80 is installed on the second circuit board portion 73, so that the sliding contact pattern 75 in the same plane as the sliding contact pattern 75 is provided. There is no need to provide the central switch 80 at the inner position, the outer diameter of the sliding contact pattern 75 can be reduced, and the outer dimensions of the multifunctional electronic component 1 can be reduced.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. It should be noted that any shape, structure, and material not directly described in the specification and drawings are within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, in each of the above-described embodiments, the case where the push button knob 10 and the central switch 80 are installed in the multifunctional electronic component 1 has been described. However, the push button knob 10 and the central switch 80 are not necessarily provided and are omitted. It is also possible to configure the multifunctional electronic component 1.

  In the above-described embodiment, the case where the first circuit board unit 71 and the second circuit board unit 73 are the flexible circuit boards 70 integrally connected via the connection arm 72 has been described. The circuit board unit 71 and the second circuit board unit 73 may be configured as separate circuit boards. In this case, at least one of the first circuit board portion 71 and the second circuit board portion 73 can be formed of a hard circuit board.

  Further, in the above embodiment, the electrical functional unit 55 is configured by the slider 66 attached to the sliding type object 60 and the sliding contact pattern 75 on the first circuit board unit 71 installed on the mounting base 90. However, as the electrical functional unit 55, other configurations may be adopted as long as the electrical output is changed by the rotation of the rotary knob 20. That is, although illustration is omitted, it is also possible to provide a sliding contact pattern on the sliding object 60 side and install a slider on the mounting base 90 side, for example, contrary to the above embodiment.

  Moreover, in the said embodiment, each switch, such as the center switch 80 formed on the flexible circuit board 70, and the press switch 78, is comprised by attaching an inversion board on the contact pattern formed in one synthetic resin film. However, these switches overlap two synthetic resin films so that a pair of contact patterns provided on both synthetic resin films face each other through a gap, and are reversed to the back side of the contact pattern provided on one synthetic resin film. It is good also as a switch (membrane switch) comprised by installing a board.
