Next, the operation of the above embodiment will be described. First, the operation of the push switch unit 58 will be described together with FIG. 11, and then the operation of the rotary switch unit 59 will be described.

A: Action of push switch portion 58 (1) When the key top 85 is pushed down in FIG. 1, the pressing projection of the key top 85 causes the push switch contact plate 5 to move.
The 3rd 1st contact part 91 is pushed in and the connection part 94 is inverted. When this deformation is referred to as a first-stage deformation, the peripheral portion 91b of the first contact portion 91 comes into contact with the contact portions 67a, 67a of the terminal 67 by this deformation, and the terminals 67, 68 are electrically connected. In this first-stage modification, the relationship between the load applied to the key top 85 and the stroke is as shown in FIG. That is, the stroke δ ranges from 0 to δ1 (= 0.
5 mm), the load P changes from 0 to the maximum value P1
After (= 0.7 Newton), it reaches (P1−ΔP1), and a click feeling occurs. ΔP1 is 0.2 Newton (about 20 g weight).

(2) Then, when the key top 85 is further pushed down, the pressing projection of the key top 85 further pushes in the first contact portion 91 of the push switch contact plate 53, and the deformation proceeds. When this deformation is referred to as a second-stage deformation, the central portion 91a of the first contact portion 91 is deformed by the deformation of the terminal 66.
The terminal 66, 67, 68 is electrically connected by contacting the contact portion 66a. As shown in FIG. 11, the relationship between the load and the stroke in the second-stage deformation is that the load P changes from (P1−ΔP1) to the maximum while the straw δ changes from δ1 to δ2 (= 0.7 mm). A value of P2 (= 2.0 Newton) is reached to (P2-ΔP2), and a click feeling occurs. ΔP2 is 0.6 Newton.

(3) When the pressing of the key top 85 is released, the key top 85 is pushed up by the restoring force of the push switch contact plate 53, and the first contact portion 91 causes the contact portions 66a of the terminals 66 and 67 to contact. 67a, 67a are separated and electrically disconnected, and the initial state of FIG. 1 is restored.

B: Action of the rotary switch 59 (1) In FIG. 1, when the rotary knob 87 is pinched and rotated clockwise or counterclockwise, the rotor 51 is rotated clockwise or counterclockwise in conjunction with this and the rotor 51 is rotated. The rotary switch contact piece 54 fixedly attached to the same also rotates. Rotor 5
1, the engaging protrusion 48 (not shown) has a housing 50.
Since it is engaged with the rotation restriction groove 49 of, the central angle is approximately 1
It can be rotated in the range of 80 degrees. Further, since the balls 55, 55 are biased by the leaf springs 56, 56 to the uneven portions 82a-82a on the outer periphery of the rotor 51, the rotor 51 rotates and a click feeling is generated when the connection between terminals described later is switched. Occurs.

(2) When the rotary switch contact piece 54 is in the position shown in FIGS. 3 and 4, one of the contact piece portions 97, 97 of the rotary switch contact piece 54 is connected to the terminal 7.
The contact portions 70a and 79a of 0 and 79 are contacted, the other contact piece portions 97 and 97 are contacted to the contact portion 75a of the terminal 75, and the terminals 70 and 79 are electrically connected to the terminal 75. Terminal 7
0 and 79 are common terminals, and their contact portions 70a and 79a are contact portions having the same wide contact surface.

(3) The rotor 51 is rotated counterclockwise from the state shown in FIGS. 3 and 4 by 22.5 at the central angle.
When it is rotated counterclockwise, the contact piece 54 for the rotary switch is rotated in conjunction with this, and one of the contact piece parts 97, 9 is rotated.
7 continues to be in contact with the contact portions 70a and 79a of the common terminals 70 and 79 (contact positions are different), but the other contact piece portions 97 and 97 switch to contact with the contact portions 76a of the individual terminals 76. . That is, the common terminals 70 and 79 and the individual terminals 76 are electrically connected. At this switching time, a click feeling occurs as described in (1) above. A similar clicking sensation occurs during the following switching.

(4) Next, when the rotor 51 is rotated counterclockwise by 22.5 degrees with respect to the center angle twice by rotating the rotary knob 87, one of the contact pieces 97, 97 of the rotary switch contact piece 54 is common. Contact portions 70a, 7 of terminals 70, 79
9a, but the other contact piece portions 97, 97 are sequentially switched to contact with the contact portions 77a, 78a of the individual terminals 77, 78. That is, first, the common terminals 70 and 79 are electrically connected to the individual terminals 77, and then the common terminals 70 and 79 are electrically connected to the individual terminals 78.

(5) Further, when the rotor 51 is rotated counterclockwise by 22.5 degrees at the central angle by rotating the rotary knob 87 counterclockwise four times, the other contact piece portions 97, 97 of the rotary switch contact piece 54 are common. Contact portions 70a, 7 of terminals 70, 79
The contact state with 9a is continued, but one contact piece 97,
97 is a contact portion 71 of the individual terminals 71, 72, 73, 74
a, 72a, 73a, 74a are sequentially switched. That is, the common terminals 70, 79 are first of all the individual terminals 7
1 electrical connection, then individual terminals 72,
Switching to electrical connection with 73, 74.

(6) As shown in (2) to (5) above, starting from the state where the rotary switch contact piece plate 54 is shown in FIGS. 3 and 4, the rotary knob 87 is rotated counterclockwise to rotate the rotor 51. It is possible to switch the connection in 8 steps by rotating the 7 times at the central angle by 22.5 degrees. Assuming that the switching is started from the state where the common terminals 70 and 79 and the individual terminals 74 are connected to each other, the clockwise rotation of the rotary knob 87 causes the rotor 51 to rotate 7 times by 22.5 degrees at the central angle. 4 can be returned to the connected state.

In the above-described embodiment, the push switch contact plate 53 has a shape as shown in FIG. 9 and the load-stroke characteristics are configured to satisfy the characteristics shown in FIG. The present invention is not limited to this. For example, the push switch contact plate 153 as shown in FIG. 12 can be used.

A thin ring-shaped connecting portion 194 separated by 2 and connected by connecting portions 193, 193;
The push switch contact plate 153 can also be used in the case where the thin rectangular second contact portions 195 and 195 projecting from the outer sides of the outer surface of the base plate 94 at opposite positions.

In the above-described embodiment, the disk portion 83 of the rotor 51 has the push switch portion 5 in order to reduce the number of parts.
Although the cover 8 is also used and the cover (22 in FIG. 16) which is individually required in the conventional example is not necessary, the present invention is not limited to this, and the push switch portion 58 is not limited thereto.
It can also be used when a separate cover is provided for each.

In the above-described embodiment, the push switch portion 58 is deformed in two stages when the push switch contact plate 53 is pressed, so that the push switch portion 58 is brought into contact with the contact portions 66a to 68a of the push switch terminals 66 to 68 in two stages. However, the present invention is not limited to this, and the contact plate for the push switch is deformed in one step when the push switch part is pressed to form the contact part of the push switch terminal. It can also be used in the case of a one-step push switch unit that is in a stepwise contact state.

In the above embodiment, the composite switch in which the push switch portion and the rotary switch portion are incorporated in the same housing has been described, but the present invention is not limited to this, and the push switch portion and the rotary encoder switch are provided in the same housing. It can also be used for composite switches that incorporate parts.
