A groove 8e is formed opposite the engagement protrusion 5b of the rotation knob 5. 9 is a rotary switch base. A circular hole 9a is bored in the center of the rotary switch base 9, and a step 9b is formed around half of the hole, and an arcuate groove 9c is formed on the opposite side of the step 9b. . Narrow grooves 9d and 9e are formed at both ends of the groove 9c to communicate with the groove 9c. Further, two fixed contacts 9f and 9g are provided on the stepped portion 9b. Note that 9h is a mounting projection. 10 is a coil spring, and 11 and 12 are spring holders, both of which are housed in the groove 9c. 13
Reference numerals a, 13b, 13c, and 13d are switch bodies consisting of known non-lock type push button switches each having a built-in return spring, and 14 is a printed wiring board, on the bottom of which a terminal 14a for extraction is attached. . Further, the printed wiring board 14 has four holes 14b and four more holes 14c formed therein, as well as a plurality of small holes into which the terminals of the switch body are inserted and soldered.

The members 5, 6a to 6d, 7, 8, and 9 are all made of insulating synthetic resin.

Next, the assembly of the switch device according to the present invention will be explained.

First, the four switch bodies 13a to 13d are mounted on the printed wiring board 14, and the coil spring 10 and spring retainers 11 and 12 are housed in the groove 9c. 14b, the head of the mounting protrusion 9h is heat caulked to attach the rotary switch base 9 to the printed wiring board 14. Next, the rotary switch body 8
is placed on the rotary switch base 9. At this time 2
The two sliders 8b are located within the stepped portion 9b, the guide arm 8c-1 enters the narrow groove 9d, and the guide arm 8c-2 enters the narrow groove 9e. In this state, the partition member 7 is inserted into the circular hole 8a, the protrusion 7b at the lower end is inserted into the hole 14c of the printed wiring board 14, and these heads are heat-stamped to fix the partition member 7 to the printed wiring board 14. do. At this time, the presser plate 7c of the partition member presses down the upper end of the upper flange 8d of the rotary switch body 8, so that the rotary switch body 8 is rotatably held on the rotary switch base 8. Finally, after inserting the pushbuttons 6a, 6b, 6c, and 6d between the partition plates 7a, the rotary knob 5 is turned over and pushed firmly, so that the engagement protrusion 5b of this is provided on the upper flange 8d of the rotary switch body 8. It snaps elastically into the groove 8e, and these are integrated. Rotary knob 5
When the button is attached to the rotary switch body 8, as clearly shown in FIG. ,6
b-2, 6c-2, and 6d-2 abut against the engaging edge 5a of the rotary knob 5 and the guide plate 7d of the partition member 7, and their heads protrude into the interior of the rotary knob 5. Fourth
The figure is a perspective view showing the external appearance of the switch device after assembly, and FIG. 5 is a circuit diagram thereof.

Next, the effect will be explained.

One terminal of each switch body 13a to 13d is connected to the common COM within the printed wiring board 14,
The other terminal of the switch body 13a is connected to the +X terminal, the other terminal of the switch body 13b is connected to the -X terminal, the other terminal of the switch body 13c is connected to the +Y terminal, and the switch body 1
The other terminal of 3d is connected to the -Y terminal.
Further, one ends of the fixed contacts 9f and 9g are both connected to the common terminal COM, the other terminal of the fixed contact 9f is connected to the +θ terminal, and the other terminal of the fixed contact 9g is connected to the −θ terminal.

For example, when the push button 6a is pressed, the switch body 13a is closed and the moving device is operated to move the bright spot 1b to the left in FIG. 1, that is, in the +X direction. Similarly, by pressing the pushbuttons 6b, 6c, and 6d one after another, the bright spot 1b is moved to -X, +Y,
- Can be moved in the Y direction.

Further, when the rotary knob 5 is rotated, for example, clockwise from the neutral position, the rotary switch body 8 moves as shown in FIG. 6a.
The state changes from the state shown in FIG. 6b, and the slider 8b closes the fixed contact 9f. For this purpose, the driving device for the bright spot 1b is operated to rotate it in the -θ direction in FIG. Note that by rotating the rotary knob 5 clockwise, the guide arm 8c-2 stores energy in the coil spring 10, so when you release your finger from the rotary knob 5, it automatically returns to the neutral position by the force of the coil spring. to return to. When the rotary knob 5 is rotated counterclockwise from the neutral position, the state shown in FIG. 6c is obtained, and the bright spot 1b driving device is operated to rotate it in the +θ direction in FIG. 1. When the rotary knob 5 is released, it automatically returns to the neutral position by the force of the coil spring 10, as described above.

As explained in detail above, according to the present invention, by operating the four push buttons, the object to be operated can be controlled to move up and down, left and right, and the rotary knob can be moved clockwise and counterclockwise. It is possible to provide a switch device that can rotate the operation target in the same direction by rotation, and each push button has a quarter circular shape, and four push buttons are grouped together in a circular shape. Therefore, when installing the switch device on the panel, the push buttons can be arranged vertically and horizontally, and the operation target can be rotated left and right by rotating the rotary knob left and right. The movement of the operation object and the operation form can be matched, making the operation easy, reliable, and quick. In addition, since four push buttons are placed inside the rotary knob, the configuration is compact, and the operation parts are located close to each other, making it possible to quickly perform multiple operations with one hand. It is suitable for use in operating switches for remote control devices, television games, etc.
