[Problems to be solved by the invention]
However, when the conductive terminal 30 of the rotary switch 19 is inserted into the terminal hole 31 of the circuit board 3 and then the conductive terminal 30 is soldered, the rotary switch 19 may be displaced. Then, the center of the through hole 21 of the circuit board 3 and the center of the switch hole 22 are displaced, so that the rotation shaft 23 does not enter the switch hole 22, and even if it does, the operation shaft 11 is pressed and then the rotation shaft 23 is pressed. 23 may be caught on the end of the through hole 21 and the operation shaft 11 may not return.

The cause of the displacement of the rotary switch 19 is that the conductive terminal 30 can be easily inserted into the terminal hole 31 even if the conductive terminal 30 is slightly inclined or the position of the conductive terminal 30 with respect to the frame 29 is slightly varied. For this reason, the diameter of the terminal hole 31 is increased. In the case of the conventional example, a round terminal hole 31 is provided for a rectangular conductive terminal 30 as shown in FIG. In this case, the position shift amount of the conductive terminal 30 is set to be maximum in the left-right direction in FIG. 13, and when the position shift is the maximum amount, the above-described problem is easily caused. To improve this, there is a method of increasing the size of the through hole 21. However, if the size of the through hole 21 is large, the coil spring 25 may fall into the through hole 21.
[0011]
The present invention has been made in view of such a point, and an object of the present invention is to provide an operating device that suppresses a position shift of a rotary switch when a rotary switch is disposed on a circuit board, thereby improving a switch operation. I do.

The conductive terminals 30 are inserted into round terminal holes 31 provided at three places of the circuit board corresponding to the conductive terminals 30 and soldered to the front side of the circuit board 3. The frame 29 includes an upper frame 29A and a lower frame 29B, and the rotating body 28 is held by the upper and lower frames 29A and 29B. Further, a frame hole 32 slightly larger than the switch hole 22 is provided concentrically on the upper frame 29A, and an annular protrusion 33 is formed on the periphery of the frame hole 32. When the rotary switch 19 is fixed to the circuit board 3 by soldering, the protrusion 33 is fitted into the through hole 21 of the circuit board 3.
[0020]
The switch hole 22 of the rotating body 28 has a D shape as shown in FIG. This is to prevent the rotating shaft 23 inserted into the switch hole 22 from idling between itself and the switch hole 22.

As a result, the position of the rotary switch 19 with respect to the circuit board 3 can be maintained even in a state in which play is likely to occur between the terminal hole 31 provided in the circuit board 3 and the conductive terminal 30 as in the conventional example. The position of the rotary switch relative to the circuit board 3 is suppressed because the protrusion is determined by the 33 places of the protrusions fitted into the through holes 21, and the turning shaft 23 can be smoothly inserted into and removed from the switch hole 22. The operation of the shaft 11 is improved. In addition, even if the gap between the through hole 21 and the protruding portion 33 is slightly loose, the upper frame 29A on which the protruding portion 33 is formed and the rotating body 28 are slightly displaced integrally.

When the operation shaft 11 is pressed, the coil spring 25 can be prevented from falling into the recess on the circuit board 3 side. In other words, the substantially oval portion 38 does not fall into the depression because the longer diameter side is larger than the through hole 21. Further, since the width on the minor diameter side is the same as the diameter of the circular portion other than the substantially elliptical portion 38 of the coil spring 25, when the coil spring 25 is compressed, the second coil spring 25 from the circuit board 3 side has a substantially long length.

Further, positioning holes 39 into which the protrusions 33A are fitted are provided at three places on the circuit board corresponding to the protrusions 33A. The through hole 21 of the circuit board 3 through which the rotation shaft 23 is inserted is larger than the switch hole 22 (the same size as in the first embodiment). The same coil spring 25 as that of the first embodiment (shown in FIG. 3) is used. That is, the circuit board 3 side of the coil spring 25 is formed as a substantially oval portion 38, the longer diameter side of the substantially oval portion 38 is larger than the diameter of the through hole 21 of the circuit board 3, and the shorter diameter side (width) is The diameter of the coil spring 25 matches the diameter of a circular portion other than the substantially oval portion 38.
[0029]
As described above, the pin-shaped protrusion 33A formed on the upper frame 29A is fitted into the positioning hole 39 provided on the circuit board 3 so that the terminal hole 31 and the conductive terminal 30 provided on the circuit board 3 Even in a state where the backlash easily occurs, the position of the rotary switch 19 with respect to the circuit board 3 is determined by the location of the protrusion 33A fitted into the positioning hole 39. , The displacement of the rotary switch with respect to is suppressed, the turning shaft 23 is smoothly inserted into and removed from the switch hole 22, and the operation of the operating shaft 11 is improved. In addition, even if the position between the positioning hole 39 and the protruding portion 33 </ b> A is slightly loose, the through-hole 21 is larger than the switch hole 22 so that the rotating shaft 23 is caught on the end of the through-hole 21. Without this, the operation of the operation shaft 11 can be performed smoothly.

By making the diameters of the circular portions other than 38 equal (to have the same diameter), even if the through hole 21 of the circuit board 3 is large as shown in FIG. 6, it is substantially oblong as in the state shown in FIG. Since the longer diameter side of the portion 38 is larger than the through hole 21, the coil spring 25 does not fall into the through hole 21. Further, since the width on the minor diameter side is the same as the diameter of the circular portion other than the substantially elliptical portion 38 of the coil spring 25, when the coil spring 25 is compressed, the second coil spring 25 from the circuit board 3 side has a substantially long length. By hitting the portion on the short diameter side of the circular portion 38, the second coil spring 25 does not fall into the through hole 21 and is not caught at the end of the through hole 21.

A pin-shaped protrusion 33A is formed on the upper frame 29A of the rotary switch 19, and the protrusion 33A is fitted into a positioning hole 39 provided in the circuit board 3. As shown in FIG. 8, the coil spring 25 has a circular portion 40 on the circuit board 3 side that is larger than the diameter of the through hole 21.
[0032]
By inserting the pin-shaped protrusion 33A into the positioning hole 39 in this manner, the position of the rotary switch with respect to the circuit board 3 is suppressed, and the rotation to the switch hole 22 is performed, as in the second embodiment. The shaft 23 is smoothly inserted and removed, and the operation of the operation shaft 11 is good. Further, since the coil spring 25 has a circular portion 40 on the circuit board 3 side that is larger than the diameter of the through hole 21, the coil spring 25 does not fall into the through hole 21. In the push-type switch 18 according to the present embodiment, the movable portion 26 is pressed before the coil spring 25 is compressed so that the second coil spring 25 from the circuit board 3 side falls into the through hole 21.
[0033]
FIG. 9 shows a fourth embodiment of the present invention. This embodiment is different from the first embodiment in the rotation shaft 23 and the coil spring 25. The rotating shaft 23 has a large-diameter portion 41 on the pressing portion 24 side and a small-diameter portion 42 on the circuit board 3 side. The size (diameter) of the small diameter portion 42 is the same as the diameter of the rotating shaft 23 in the first embodiment. Therefore, the diameter of the through hole 21 of the circuit board 3 is the same as that of the first embodiment. The size (diameter) of the coil spring 25 corresponds to the large diameter portion 41 of the rotating shaft 23, and is constant from the pressing portion 24 side to the circuit board 3 side.

In the first embodiment, the circuit board 3 side of the coil spring 25 is formed into a substantially elliptical portion 38. However, the movable portion 26 of the push-type switch 18 is pressed by the second coil spring 25 from the circuit board 3 side. If it is performed before the coil spring 25 is compressed so that it falls into the hole 21, the circular portion 40 may be the same as the third embodiment.
