Description

[Detailed explanation of the invention] This invention relates to a multi-directional switch. Specifically, this invention uses two motors to switch the electric mirror of a car in eight directions: up, down, left, right, and diagonally (top right, bottom right, top left, bottom left). This is suitably used for a switch that operates to switch between.

Conventionally, this type of multi-directional switch has had the disadvantage that when operating the operating knob to change the switch, since it does not have a moderation mechanism, there is no sense of moderation and erroneous operation is likely to occur.

This invention aims to eliminate the above-mentioned conventional drawbacks, and is characterized by providing a moderation mechanism between the operating member and the guide ring that moves up and down due to the tilting of the operating member, thereby creating a sense of moderation. The present invention provides a multi-directional switch.

In order to achieve the above object, the present invention displaces a movable contact by tilting an operating member supported by a spherical bearing so as to be tiltable in multiple directions with respect to a switch body, and the movable contact is moved toward and away from a fixed contact attached to an insulator. In the multi-directional switch, a cylindrical guide ring is arranged around the shaft of the operating member, a radially protruding collar is provided on the guide ring, and the tip of the collar is brought into contact with the operating member. a moderation groove is formed on one of the tip of the collar portion of the guide ring and the abutment portion of the operating member, and an engagement portion that engages with the moderation groove is formed on the other side, and the collar portion of the guide ring and the switch A return spring is compressed between the body and the guide ring abutting portion of the operating member is tilted around the spherical bearing due to the tilting operation of the operating member. The multi-directional multidirectional device is characterized in that the contact portion of the operating member slides while being pressed in the vertical direction against the pressure to engage and disengage the moderation groove and the engagement portion, and the engagement and disengagement produces a feeling of moderation. It provides a switch.

This invention will be explained in detail below with reference to embodiments shown in the drawings.

In addition, a return spring 19 is compressed between the lower surface of the collar portion 20a and the bottom portion 1d of the knob support portion 1b. Therefore, when the top surface of the operating knob 2 is pressed and the operating knob 2 is tilted around the pivot 18, the operating knob 2
The moderation groove 2b is located at the tip end 20b of the guide ring 20.
It is difficult to operate because you have to press down while sliding. However, when the operation knob 2 is further moved, the engagement state of the side ring abutting portion of the operation knob 2, that is, the engagement state of the moderation groove 2b and the tip portion 20b that constitutes the engagement portion becomes as shown in FIG. 2B. The distal end line of the moderation groove 2b comes into contact with the distal end portion 20b, making the operation easier.
That is, in the multi-directional switch according to the present invention, at the beginning of movement, the moderation groove 2b of the operation knob 2 and the guide ring 20
The operation is heavy due to the engagement of the tip 20b of the operation knob 2, but when the engagement state is removed, the operation feeling becomes lighter and the operation knob 2
You can gain a sense of moderation in your operations. Also, when the pressure on the operation knob 2 is released, the return spring 19
As a result, the operating knob 2 is pushed up and automatically returned via the guide ring 20, and the guide ring tip end 20b is just fitted into the moderation groove 2b, so that it is stopped and held. The upper surface operation part 2c of the operation knob 2

On the free end side of 14, common fixed contact plates 16 and 17 extending in the front-rear direction are attached to the insulator 15 with an interval in the vertical direction, and the movable contact plate 11 is attached to the lower surface of the upper fixed contact plate 17. The free ends of ~14 are kept in pressure contact at all times. Therefore, when the operating knob 2 is pushed down and the indenters 3 to 10 descend, the protrusions 3c to 6c push down the movable contact plates 11 to 14 so that the free ends abut the lower fixed contact plates 16 and 17. . Fixed contact plate 16 common to the above
and 17 are connected to both poles of the power supply 24.

Next, the switching action of the switch configured as described above will be explained. When the operation knob 2 is in the neutral OFF position, the indenters 3 to 10 are urged by the movable contact plates 11 to 14 and are in the upper position, and the free ends of the movable contact plates 11 to 14 contact only the upper fixed contact plate 17. However, since none of them are in contact with the lower fixed contact plate 16, the circuit is open.

If you want to tilt the mirror upward, use operation knob 2.
When the upward operating surface 2c-2 is pressed, the operating knob 2 is tilted about the pivot 8, and the upward operating surface 2c-2 is tilted.
-2 pushes down the upper indenter 3 that is in contact with the lower surface of the indenter 3, and pushes down the upward movable contact plate 11 with its protrusion 3c.
The free end of the contact plate 11 is detached from the upper fixed contact plate 17 and comes into contact with the lower fixed contact plate 16. Therefore, power supply 24 - fixed contact plate 17 - movable contact plate 12
