Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention is suitable for cases where a single lever is used to perform a dimming operation for switching between high beam and low beam and a passing operation for flashing the high beam. Regarding the switch device.

(Prior art) For example, in a switch that performs daylight operation and passing operation by pulling a lever, when the lever is operated about half of its stroke, the movable contact inside the switching part for passing moves to one fulcrum. It is turned on by being turned in one direction around the lever, and when the lever is operated at its full stroke, the switch section for the daylight is operated.

(Problem that the invention aims to solve) However, since the lever is further operated after the passing switch part is turned on and the daylight switch is switched, even after the passing switch part is turned on, the movable contact holder inside will be further rotated in one direction, and space must be provided for this rotation.
The drawback is that the switch case becomes larger. It has also been considered to provide an escape mechanism to prevent the movable contact holder of the pushing switch from rotating even if the lever is further operated after the pushing switch is turned on, but this would complicate the configuration and make assembly difficult. There are certain drawbacks.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a switch device that can be manufactured in a small size, has a simple structure, and is easy to assemble.

[Structure of the invention] (Means for solving the problem) The present invention is equipped with a momentary type switch in which the switching state changes when the operating member moves a full stroke, and the operating member moves in one direction. A movable member to which a moving force is applied approximately in the middle when rotated is provided, and a spring member is provided to apply a biasing force in a direction opposite to the direction of the moving force applied by the operating member to a position on one end side of the movable member. and the movement of one end of the movable member is restricted by the biasing force of the spring member and the one end thereof is rotated while the operating member is moved from the start of movement to a predetermined stroke of the entire stroke. By rotating as a fulcrum, the state of contact and separation between the movable contact provided on the movable member and the fixed contact provided on the switch case is changed, and when the operating member is moved beyond a predetermined stroke, the The movement of the other end of the movable member is restricted and the one end of the movable member is moved against the biasing force of the spring member by performing a rotational movement using the other end as a rotational fulcrum. The present invention is characterized in that the state of contact and separation between the movable contact and the fixed contact is maintained in the changed state while the operating member is moved from a predetermined stroke to a full stroke.

Next, the operation of this embodiment configured as above will be explained with reference to the drawings. Figures 2, 3, 5, and 6 where the operating member 3 is not pressed
In the state shown in the figure, the operating member 3 is urged upward by the return spring 4 and engages with the claws 6, 6, and is movable, for example, when the rotating member 10 is rotated in the direction of arrow A. Contact 13 is a fixed contact
The movable member 22 is in contact with ED and HL, respectively, and the movable member 22 is pushed upward by the coil spring 32 so that the contact protrusion 25 of the movable contact 25
d and the contact protrusion 27 are spaced apart from the fixed contacts HF and ED', respectively. Next, by rotating a lever (not shown), the operating member 3 is returned to the spring 4.
When the operating pin 18 moves downward in the direction of arrow B, the lower end of the operating pin 18 rotates in the direction of arrow C while slidingly contacting the side surface of the engagement groove 20, and the operating member 3 moves through a predetermined stroke of about half of the total stroke. d When pressed down, the lower end of the operating pin 18 engages with the bottom of the engagement groove 20 (see the two-dot chain line in FIG. 2 and FIG. 7).
On the other hand, when the operating member 3 is moved in the direction of arrow B, the interlocking body 28 moves in the same direction, and the bent portion 28a pushes down the center portion of the movable member 22.
Then, the movable member 2 is pushed down by the bending portion 28a.
The movable contact 25 rotates in the direction of the arrow D using one end x near the directly upper part of the coil spring 32 as a rotation fulcrum, and when the operating member 3 is pushed down by a predetermined stroke d, which is about half of the total stroke, the movable contact 25 The contact protrusion 27 contacts the fixed contact ED', and at the same time the contact protrusion 25d contacts the fixed contact HF (see FIG. 8).

Now, from the state shown in FIGS. 7 and 8, the operating member 3
is further moved downward in the direction of arrow B, the operating pin 18 engaged with the bottom of the engagement groove 20 rotates the rotating member 10 in the direction of arrow E, and the operating member 3 moves in the direction of arrow E. When the rotating member 10 is moved through the entire stroke in the direction B, the rotating member 10 is rotated in the direction of the arrow E as shown in FIG. 9, and the movable contact 13 is in contact with the fixed contacts ED and HU. Then, in the middle of the rotation of the rotating member 10 in the direction of arrow B, the moderation peak 16 comes to overcome the moderation piece 17, and the biasing force of the spring 15 applied to the moderation piece 17 causes the rotation member 10 to move to the third position. The state shown in FIG. 9 is maintained. Then, when the rotation of the rotation member 10 is completed and the operation member 3 is returned upward in the opposite direction of arrow B by the biasing force of the spring 4, the operation pin 18 comes out of the engagement groove 20 (not shown). The operation pin 1 is returned to the neutral state by the spring.

Since it is in contact with ED', bending part 2 from this state
When the movable member 8a is moved downward, the movable member 2 is moved around the contact point Y between the contact protrusion 27 located at the other end of the movable member 22 and the fixed contact ED' as a pivot point.
2 makes a rotational movement in the direction of arrow F, and coil spring 3
2 is compressed, and the circular convex portion 23 slides within the guide groove 24. When the operating member 3 is moved by the full stroke in the direction of arrow B, the state shown in FIG. 10 is reached. Further, at this time, the contact convex portion 25c of the movable contact 25 continues to contact the fixed contact HU' while rotating in the direction of the arrow F about the Y point. Then, as described above, when the operating member 3 is returned upward in the direction opposite to the arrow B by the biasing force of the return spring 4,
Since the downward moving force due to the bent portion 28a of the interlocking body 28 is eliminated, the movable member 22 is moved by the coil spring 32.
It is returned to its original state as shown in FIGS. 3 and 6 by the urging force of FIG. Thereafter, when the operating member 3 is moved from the uppermost position to the direction of arrow B, the operating pin 18 engages with the engagement groove 21, and the rotating member 1
0 is rotated in the direction of arrow A to return to the original state shown in FIG. done to. That is, the rotating member 10, the movable contact 13, and the fixed contact ED,
Arrow D of the movable member 22 that is performed during the movement of the operating member 3 from the start of movement to a predetermined stroke d for the entire stroke of the operating member 3 when switching a momentary type day switch consisting of HU and HL. The switching operation of the passing switch consisting of the movable contact 25 and fixed contacts HF, ED', and HU' is completed based on the rotation in the direction, and therefore, one lever operates only a part of the total operating stroke. When the stroke is completed, the passing operation is performed, and when the full stroke operation is performed, the demerger is switched.

In the above embodiment, the daylight switch was constructed using the movement of the movable member 22.
It is also possible to configure a switch other than a passing switch by setting the positions of the movable contact and the fixed contact so that they make selective contact by utilizing the rotation in the direction of arrow F of 2.

In the embodiment described above, as the operating member 3 is moved by a predetermined stroke of about half of the total stroke, the movable member 22 moves along the arrow D with one end X as the center.
The rotating member 22 rotates in the direction of the arrow F around Y at the other end while the operating member 3 is further operated and moved through the remaining half stroke until the full stroke. , compared with the conventional movable member in which the movable member is rotated about one fulcrum during the entire stroke of movement of the operating member, the movable member 22 of the above-described embodiment is
, the movement stroke is smaller, and therefore, in the above-described embodiment, the size of the switch case 1 can be made smaller than that of the conventional one, making it possible to downsize the entire device. 3, the rotary member 22 always moves in response to the operation, and therefore, there is no need for a structure in which the movable member escapes during the movement of the operating member, as in the conventional case, so that the movable member does not move during the movement of the operating member. The structure is simple and easy to assemble.

[Effects of the invention] As is clear from the description of the embodiments described above, the present invention can reduce the amount of movement of the movable members, so it can be downsized, and moreover, the necessary functions can be achieved with a small number of parts. Therefore, it is possible to provide a switch device that has a simple structure and can be easily assembled, which has practical effects.
