Abstract

PURPOSE:To reduce the number of components and construct the device in a small size. CONSTITUTION:A contact piece 400 is furnished on a slider 4, and the line segment tying the two movable contacts 403, 404 of the contact piece 400 is inclined with reference to the four moving directions of the contact piece 400. When an operating piece 3 is rotated in four directions, the contact piece 400 moves in four directions on a circuit board 5 while the slider 4 is interposed, and thereby the first, second, third, and fourth circuits are formed. Accordingly four circuits can be formed from one contact piece 400 to result in use of a smaller number of components. Because the line segment as mentioned above is inclined with reference to the four moving directions of the contact piece 400, the sliding distance of the slider 4 can be lessened and the switch device be constructed small. Further because the contact piece 400 can be made long, it is possible to lessen the spring stress of the contact piece.

It consists of 04. The plate portion 401 has a central horizontal portion,
It is composed of an inclined portion formed by bending both ends of the horizontal portion obliquely downward, and a contact portion formed by folding back the tip of the inclined portion slightly upward. Then, due to the elastic action of the inclined portion, the movable contacts 403 and 404 cause the conductors 51, 52, 5 to move.
Since they are in elastic contact with the conductors 3, 54 and the output-side conductor 55, electrical conduction is good. The engaging claw 402 extends substantially horizontally from the plate portion 401, and the tip end thereof is bent obliquely downward.

Then, the two movable contacts 403 and 404 of the contact 400 are elastically brought into contact with the circuit board 5. For convenience of drawing, the contact 400 in the drawing may be illustrated thicker than it actually is.

The four-way switch device of the present invention in this embodiment is constructed as described above, and its operation will be described below. Normally, the operation body 3 is located at the neutral position as shown in FIG. 3 by the action of the compression coil spring 34, the bush 35, and the cross-shaped inclined surface 104 of the automatic return means. That is, the compression coil spring 34
Due to the elastic action of the bush 35, the bush 35 has a cross-shaped inclined surface 1

In addition, as the operating body 3 rotates (tilts), the engaging rod 330 of the operating body 3 rotates (tilts) in the direction opposite to the tilting direction of the knob 8, and the tilting action of the engaging rod 330 causes the slider to slide. 4 slides on the circuit board 5 in the same direction as the tilting direction of the engaging rod 330. When the slider 4 slides in the direction of arrow U in FIG. 5, for example, the contact 400 integrated with the slider 4 also slides in the same direction, and one of the two movable contacts 403 of the contact 400 has the first conductor 51 and the second conductor. Conductor 52, third conductor 53, fourth conductor 5
Of the four, for example, the first conductor 51 contacts the position of 403U, and the other movable contact 404 contacts the position of the output conductor 55, for example, the 404U. As a result,
For example, as shown in FIG. 17, the contact 400 of the switch element U of the first resistor R1 contacts the first conductor 51 and the output-side conductor 55, respectively, and the circuit of the first resistor R1 is closed. .

Then, the tilting operation of the knob 8 of the operating body 3 is stopped.

The contact 400 of the switch element U of the first resistor R1 is separated from the first conductor 51 and the output-side conductor 55, and
The circuit of the resistor R1 is opened.

When the knob 8 of the operating body 3 is tilted in the other three directions, the operating body 3 is tilted in the predetermined direction as described above, and accordingly, the slider 4 and the contact 400 are also moved in the predetermined directions.

When the operation of the knob 8 is stopped, the operation body 3 is automatically returned to the neutral position by the automatic return action of the automatic return means, and the slider 4 and the contact 400 are automatically returned to the neutral position accordingly. Therefore, the two movable contacts 403 and 404 of the contact 400 are separated from the second conductor 52 and the output-side conductor 55, from the third conductor 53 and the output-side conductor 55, to the fourth conductor 54 and the output-side conductor 55.
From each other, the contact 400 of the switch element D of the second resistor R2 is separated from the second contact as shown in FIG.
The circuit of the second resistor R2 is opened apart from the conductor 52 and the output-side conductor 55, or the contact 400 of the switch element L of the third resistor R3 is separated from the third conductor 53 and the output-side conductor 55, and The circuit of 3 resistor R3 opens,
Alternatively, the contact 400 of the switch element R of the fourth resistor R4

1, 52, 53, 54, 55 and the contact 400 that slides integrally with the operating body 3 via the slider 4 can replace the four switch units, so that a comparison with a conventional four-way switch device is required. The number of parts is small. Further, since one contact 400 constitutes a movable contact, the number of constituent parts can be smaller than that of a slide type switch device using a coil spring, a plate contact and a ball contact.

Particularly, in the four-way switch device of the present invention, the line segments connecting the two movable contacts 403 and 404 of the contact 400 are inclined by 45 ° with respect to the four-direction slide of the slider 4 and the contact 400. Therefore, the moving distance of the contact 400, that is, the slider 4
The sliding distance can be reduced, and the switch device can be downsized accordingly. Moreover, even if the switch is downsized, the two movable contacts 403 and 404 of the contact 400 are
Since the length to connect to can be increased, the contact 40
The spring stress of 0 can be reduced. The inclination of the line segment connecting the two movable contacts 403 and 404 of the contact 400 with respect to the above-described slide of the slider 4 and the contact 400 in four directions may be other than 45 ° described above.

Further, in this embodiment, the spherical portion 30 of the operating body 3 is rotatably supported at a position above the circuit board 5, and the slider 4 and the contact 400 are fixed to the circuit board 5.
Since it is configured to slide upward, a through hole for inserting the slider 4 and the operating body 3 for sliding the contact 400 on the circuit board is not necessary. As a result, the conductors 50, 51, 52, 53, 5 of the circuit board 5
It is easy to configure the patterns of 4, 55.

The operating direction of the operating body 3 in the above embodiment is a cross shape in which the adjoining operating directions form 90 °, but the adjoining operating directions may be other than 90 °.
