Next, the switch plate 90 is configured by attaching a click plate 93 made of an elastic metal plate on the switch contact provided on the flexible substrate 91.

In order to assemble the rotary electronic component with the push button switch, first, as shown in FIGS. 3A and 3B, the switch plate 90 is placed on the bottom 73 of the mounting base 70 and the switch plate 90 is mounted. The small projections 89, 89 inserted into the mounting holes 95, 95 (see FIGS. 1 and 2) are fixed by heat caulking.

Next, the assembled rotary electronic component 1
The outer surface of the base 40 is in contact with the surface of the main body 71 of the mounting base 70. At this time, the plate portion 47 is positioned above the protrusion 77, and the locking piece 51 and the engaging portion 53 are inserted into the hole 79 (the locking portion 83 is between the locking piece 51 and the engaging portion 53). ), And the engaging pieces 55, 55 are inserted into the upper portions of the rails 87, 87 in the through holes 85, 85.

When the rotary electronic component 10 is pressed downward from the state shown in FIG. 3 and is slid in the direction of arrow A, the L-shaped portions at the tips of the engagement pieces 55, 55 are rails. At the same time, the locking piece 51 is pressed into the locking portion 83 and the elastic member 81 is snapped into the lower side of the locking portion 83 while bending the elastic member 81 in the arrow B direction. The protrusion 77 is inserted into the guide 49, and FIG.
The state shown in (a) and (b) is obtained. Note that this locking piece 51
A snap-in mechanism is constituted by the elastic member 81 and the elastic member 81. The pressing portion 57 is located on the click plate 93.

That is, according to the present embodiment, the snap-in engagement of the rotary electronic component 10 with the mount 70
A rotary electronic component with a push button switch can be easily assembled with one touch. After assembling the rotary electronic component with the push button switch, the locking piece 51 and the locking portion 8
By the engagement of 3, there is no possibility that the rotary electronic component 10 comes off the mounting base 70.

When the rotary knob 20 is rotated, the slider 23 slides on the pattern 37 of the flexible substrate 30 to change its electrical output (for example, output of resistance value or output in on / off state). When the rotary knob 20 is rotated, the resilient portions 65 of the click plate 60 are rotated.

A mechanism in which the rail 55 and the rails 87 are engaged with each other is referred to as a forward / backward movement restricting mechanism, and a mechanism in which the engaging portion 53 is inserted into the hole 79 is referred to as a widthwise movement restricting mechanism.

That is, in the present embodiment, the rotary electronic component 10 is moved in the left-right direction (width direction, ie, arrow D direction) of FIG. This prevents play in the depth direction (the direction in which the base 40 separates from the mounting table 70, ie, the direction of arrow E). A back-and-forth movement restricting mechanism including the engagement pieces 55, 55 and the rails 87, 87 prevents backlash in the depth direction (the direction of the arrow E) in the drawing. Further, since the width of the engaging portion 53 constituting the width direction movement restricting mechanism is substantially the same as the width of the hole 79, the right and left sides of the engaging portion 53 and the right and left sides of the hole 79 abut on each other. The backlash in the left-right direction (the direction of arrow D) in (b) is prevented.

That is, since the rotary electronic component 10 is restricted so as not to move with respect to the mounting table 70 in the right-left direction and the front-back direction of the drawing, play in all directions can be prevented.

Further, in the above embodiment, the hole 79 penetrating through the mounting base 70 is provided, but instead of the through hole, a rectangular shape extending in the vertical direction (the right and left sides extending in the vertical direction need not be rectangular, but are parallel to each other). (Any shape may be used as long as it has the shape described above.).
