It has a daylight switch that switches on the main and sub headlights at night, and a day switch that flashes the main headlights during the day and alternately flashes the main and sub headlights at night to issue an overtaking signal. This relates to a daylight/pulling switch that also functions as a pulling switch.

Conventionally, this type of daylight switching switch has been constructed as shown in FIGS. 1 to 6. Reference numeral 1 denotes a main body made of synthetic resin with a hole 2 formed in the center through which the steering shaft is inserted.A tube shaft 4, which is provided integrally with an operating frame 3, is inserted into the main body 1 from the top surface of the main body 1, and is set at a neutral position N. It is pivoted so that it can rotate freely from the right R to the left L. An operating lever 6 is incorporated into this operating frame 3 by a pin 5 so that it can swing only in the vertical direction, and the operating frame 3 corresponding to the tip of the operating lever 6 moves the operating lever 6 in three steps up and down. A moderation fitting 7 is provided to hold the operating lever 6 and provide moderation of the operation. In addition, a sliding body 9 equipped with a coil spring 8 is fitted into the tube shaft 4, which is provided integrally with the operating frame 3, so as to be pushed upward at all times and constantly interlocked with the operation lever 6.
The tip of this sliding body 9 controls a daylight passing switch. That is, this daymap switching switch has three movable contact pieces 10, 11, 12 connected to an insulating plate 3 by screws on the main body 1 as shown in FIG.
8, 39 to the terminal plate 14 with the rivet 16, and one fixed terminal 13 is fixed to the terminal plate 14 with the rivet 16.
A daytime passing switch configured by being attached to the terminal plate 14 is fixed by 5.

A flange 19 is provided at the lower end of the sliding body 9, and this flange 19 has a continuous keyhole consisting of a large diameter through hole for passing through the flange 19 of the movable contact piece 10 and a long hole for passing the sliding body 9 through. 20 , and the lower end of the sliding body 9 fits into the elongated hole 21 of the movable contact piece 11 .

Note that 17 and 18 in the figure are boss portions to which the terminal plate 14 provided on the main body 1 is fixed.

FIG. 3 shows the state in which the operation lever 6 is in the lowest position, that is, the HU (upper beam illuminating the farthest distance) state, in which the movable contact piece 10 is pushed up by the collar 19 of the slider 9, and the movable contact piece 10 is pushed up by the collar 19 of the slider 9. 11 and 12 are in contact.

When the operating lever 6 is rotated upward from this state, the sliding body 9 is moved downward as shown in FIG. 4, and all the movable contact pieces 10 to 12 return to their natural states without being subjected to any external force. , the movable contact pieces 10 and 11 come into contact, the movable contact piece 12 becomes neutral, and the headlamp is switched to low beam (HL).

Further, when the operating lever 6 is rotated upward, the fifth
As shown in the figure, the sliding body 9 also moves further down and the collar 19
the movable contact piece 11 at the lower end of the sliding body 9, and the movable contact piece 1 at the lower end of the sliding body 9.
2 is moved downward, the movable contact piece 11 is in a neutral state, the movable contact piece 12 is brought into contact with the fixed terminal 13, and a passing operation (HF) as an overtaking signal is performed. If the operating force on the operating lever 6 is released in this state, the operating lever 6 automatically returns to the HL position.

Due to the above configuration, the movable contact piece is mainly
Three pieces are required, one for the auxiliary headlight circuit and one for the power supply, and
Since it is necessary to cut off the auxiliary headlamp circuit and leave only the main headlamp circuit due to the fuse capacity during the passing operation, an L-shaped bent portion 22 is required on the movable contact piece 10. Since the movable contact pieces 10 to 12 require durability, phosphor bronze plates or the like having spring properties are generally used. If the movable contact piece is bent a lot, the mold structure becomes complicated, which not only increases the cost, but also causes problems such as large variations in bending height due to the spring material, making it difficult to achieve dimensional accuracy. From this point of view, a switch structure using a leaf spring is required to have a structure with a minimum amount of bending, to be as close to straight as possible, and to minimize the number and type of movable contact pieces. ing.

From this point of view, the present invention reduces the number of movable contact pieces, reduces bending, and suppresses dimensional variations.
It is an object of the present invention to provide a daytime passing switch with a new configuration using a switching fitting.

Embodiments of the present invention will be described below with reference to FIGS. 7 to 12. Incidentally, in the drawings, the same parts as in the prior art are denoted by the same reference numbers, and the overall structure is basically the same as that shown in FIGS. 1 and 2.
Here, a switch section different from the conventional one will be explained in detail. A through hole through which the sliding body 9 is inserted is provided in the center of the terminal plate 14, and a projecting wall 2 is provided on one side of the lower surface.
8 is provided.

A movable contact piece 3 is attached to one end of the lower surface of the terminal plate 14.
1 and 32 are fixed with rivets 37 via an insulating plate 33 so as to maintain a constant insulating distance.
In the middle part of this movable contact piece 31, the collar 1 of the sliding body 9 is provided.
A keyhole 20 is provided, which is a continuous keyhole 20 consisting of a large diameter hole through which the slider 9 is inserted and a long hole into which the small diameter portion of the slider 9 is fitted.

Further, two fixed terminals 34 and 35 are fixed to the other end of the lower surface of the terminal plate 14 by rivets 36 and 50, and the fixed terminal 34 is arranged so as to correspond to the lower side of the free end of the movable contact piece 32. However, the fixed terminal 35 is connected to the power supply side instead of the conventional movable contact piece 11 and is arranged between the free ends of both the movable contact pieces 31 and 32.

Furthermore, the projecting wall 28 has two stopper pins 29,
30, and a switching fitting 24 is pivotally connected to an intermediate portion of the stopper pins 29, 30 by a support pin 25. The switching fitting 24 has a substantially doglegged shape, and its middle portion is pivoted by a support pin 25, with protruding pieces 42 bent at right angles at both ends and protruding forward.
43 are provided.

Further, one end 40 of the helical spring 23 is held at the end of the switching fitting 24 on the protruding piece 43 side by a cut-and-raised piece 26 of the switching fitting 24, and the other end 41 is latched to the stopper pin 30. The switching fitting 24 is always urged to rotate clockwise by the spring 23.
Therefore, the protruding piece 42 side of the switching fitting 24 is always in contact with the stopper pin 29 and its rotation is restricted.

With this configuration, when the operating lever 6 is at its lowest position as shown in FIG. The movable contact piece 32 is not subjected to any external force and comes into contact with the fixed terminal 35 to turn on the main headlamp into the upper beam state (HU) of the headlamp.

Next, as shown in FIG. 10, when the operating lever 6 is moved upward to an intermediate position, that is, so that the sliding body 9 is in the intermediate position, the lower end of the sliding body 9 pushes down the movable contact piece 32, and the fixed terminal 35 The movable contact piece 31 that had been lifted becomes free and comes into contact with the fixed terminal 35, and the headlamp turns on the auxiliary headlamp into a low beam state (HL). At this time, the switching fitting 24 is attached to the collar 19 of the sliding body 9.
The protruding piece 43 contacts the switching fitting 24 and rotates slightly counterclockwise against the helical spring 23.

When the operating lever 6 is further moved upward as shown in FIG. 11, the sliding body 9 is moved downward, and the movable contact piece 32 is further moved downward at the lower end to contact the fixed terminal 34, and the flange 19 pushes the protruding piece 43 of the switching fitting 24 and further rotates the switching fitting 24 in the counterclockwise direction.
As a result, the free end side of the movable contact piece 31 is pushed up and separated from the fixed terminal 35, and the main headlight is turned on.

If the operating force of the operating lever 6 is released in this state, the sliding body 9 will be pushed up by the elasticity of the coil spring 8 and the movable contact pieces 31 and 32 and automatically return to the low beam position, and the pushing will occur above and below the beam. I can do it.

In addition, Fig. 13 shows an example of a circuit using the same switch, and 45 is a battery, 46 is a fuse, 47 is a main headlamp, 48 is a sub-headlamp, and 49 is a lighting switch, and the drawing shows the HU state. There is.

As described above, the daylight passing switch of the present invention has upper and lower fixed terminals, movable contact pieces for the sub and main headlights that connect and separate these terminals, and a contact piece for the sub headlights and the upper and lower terminals when in the passing position. The structure is simple, and the movable contact piece is almost flat, making it easy to manufacture and having excellent dimensional accuracy, which is advantageous in terms of cost. Therefore, it is possible to reduce the size,
It has the advantage of being extremely stable in terms of quality, and is of great practical value.
