Description

[Detailed explanation of the invention] [Field of industrial application] This invention is a combination switch, more specifically, it combines the functions of a position selection switch and a changeover switch.
This invention relates to a compound switch that is particularly effective for use in automobiles and the like.

[Conventional technology]

Composite switches have traditionally been widely used to control the operation of multiple interconnected devices.
Various types have been proposed in Utility Model Application No. 55-59426. In the conventional combination switch,
In the case of a switch that has both a position selection switch and a changeover switch, it is necessary to separately provide an operation knob 2' for the position selection switch and an operation knob 2'' for the changeover switch, as shown in Figures 5 and 6. Furthermore, the present applicant had proposed a composite switch consisting of a single operation knob in Utility Application No. 13734/1980, but this composite switch did not have a switching function.

[Problem that the invention attempts to solve]

In this way, when trying to provide a combination switch with both position selection and switching functions, multiple knobs were required, which made operation difficult, and it also took up a large amount of space, making it impossible to miniaturize. . Therefore, it was unsuitable for use as a switch for use in automobiles, which strongly requires good operability without the risk of erroneous operation and compactness.

This invention relates to an improvement of a compound switch that the present applicant had already proposed in Utility Application No. 13734/1983, and a single operation knob is configured to be able to operate in two modes: rocking operation and pressing operation. To provide a complex switch with good operability, which allows a single operating knob to share a position selection function and a switching function, and allows position selection and switching to be performed with a single operating knob.

Furthermore, another object is to provide a composite switch that has a simpler structure than conventional composite switches, has good assembly and operability, can be easily miniaturized, and can reduce costs. It is in.

[Means for solving problems]

A switch case having a substantially rectangular cylindrical shape and having a pole plate in a lower opening, an inner case slidably provided within the switch case, a push lock mechanism for locking the inner case in a downward position, and the inner case. an operation knob supported on the upper part of the case so as to be able to swing left and right; a first switch section that acts as a switch when the operation knob is swung left and right; and the inner case that is movable downward when the operation knob is pressed. The present invention attempts to solve the above-mentioned problems of the conventional art by constructing a composite switch with a second switch section acting as a switch via the second switch section.

[Effect]

A single operating knob is provided in the upper opening of the switch case for rocking movement and push operation,
Using rocking motion as a position selection switch,
Press operation is used as a changeover switch. When the operating knob is pressed, the inner case is locked in a downward position by the push-lock mechanism, and the contacts are brought into contact and separated, and this state is maintained. Furthermore, when the operating knob is pressed once more, the push-lock mechanism is released, the inner case returns to the upper position, and the contact group is switched.

Furthermore, the movable body 4 in the second switch section 42
23 is the inclined surface 423, as shown in FIG.
The protrusion 423b protruding from the inner case 3 comes into contact with the inclined surface 316a of the operating rod 316 provided on the inner case 3, and as the inner case 3 moves up and down, the concave groove 4
It is configured to be slidably movable within 21.

Furthermore, since the compound switch has the above-described configuration, the lamp 432 for illumination can be placed at the lower center of the operating knob 2.

Next, the operation of the above compound switch will be explained.

First, the swing motion will be explained.

Move the operating knob 2 from the position shown in Figures 2 and 3.
When the operating knob 2 is swung in the _S1 direction or the _S2 direction, the operating knob 2 is swung around the shafts 23a and 23a,
In addition, it is held at a predetermined swinging position by a moderation mechanism consisting of a moderation ridge 25a provided on the hanging piece 25 and a steel ball 318c biased by a coil spring 318b. By swinging, the operating knob 2 linearly moves the arm 412a of the movable body 412 inserted into the elongated hole 24a of the hanging piece 24. That is, the movable body 412 moves in conjunction with the swinging of the operation knob 2.
slides on the pole plate 4, and the fixed contact piece 4 of the pole plate 4
11 and movable contact pieces 414a, 414 of the movable body 412
b approaches and separates, and the first switch section 41 is activated.

Next, the pressing operation will be explained.

When the operating knob 2 is pressed in the P direction from the position shown in FIG. 3, the inner case 3 moves in the direction of the pole plate 4 in conjunction with the operating knob 2 while elastically deforming the return springs 315, 315. The movement of the inner case 3 causes the movable body 423 of the second switch portion 42 to move in the right direction in FIG. 3 via the operating rod 316. Due to the movement of the movable body 423, the groove 4
Fixed contact piece 422 provided in 21 and movable body 42
The movable contact piece 425 provided at the second switch portion 425 moves toward and away from the second switch portion 41, thereby operating the second switch portion 41. At this time, the tip of the lock pin 57 pressed by the leaf spring 54 moves within the heart cam groove 51 and locks the inner case 3 in the lower position. Therefore, the operation of the second switch portion 41 is maintained, and even if the pressing operation of the operating knob 2 is released, the inner case 3 does not return to the original position shown in FIG. 3. On the other hand, when the operating knob 2 is pressed again, the tip of the lock pin 57 moves further within the heart cam groove 51 to release the lock, and the inner case 3
The elastic force of the return springs 315 returns it to the original position shown in FIG. As the inner case 3 moves back, the movable body 423 also returns to its original position due to the elastic force of the coil spring 426.

Furthermore, the above-mentioned pressing operation is not only movable no matter which swing position the operating knob 2 is in, but also a swinging operation can be performed with the operating knob 2 in a locked state. Therefore, position selection can be performed by the swinging operation, and switching can be performed by the pressing operation, and one operation knob can hold the position selection function and the switching function.

Next, the illumination section 43 is used for night illumination or as an operation indicator.

[Effect of idea]

As detailed above, the compound switch of the present invention is
Its single operating knob has two rocking and pressing movements.
In addition to being configured to enable mode operation, the operating knob can be held in a pressed state using a push-lock mechanism, allowing a single operating knob to have a position selection function and a switching function, making it independent like conventional knobs. It does not require multiple operation knobs, is troublesome to operate, and has good operability.

Furthermore, since the number of parts is reduced and the structure is simplified compared to the prior art, ease of assembly is improved, and in addition, miniaturization and cost reduction can be achieved.

Furthermore, a sliding movable inner case is provided inside the switch case, and the operating knob is configured to be able to swing freely at the upper part of the inner case, so that stable swinging action can be achieved even in harsh environments such as automobiles. It has an excellent effect of providing dynamic and pressing operation.
