Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a switch operation in which the respective operators of two sliding switches are arranged adjacent to each other.

[Prior art]

Conventionally, in order to prevent two switches from being closed at the same time, a restricting member was installed between the two operators, and when one operator was operated, the restricting member was activated. Move it to the other controller side,
This restricts the operation of the other operator. However, in the above configuration, a regulating member must be provided as a bridge between the two operating elements, resulting in a complicated structure and a corresponding increase in cost.

[Purpose of invention]

This idea was made in view of the above circumstances.
The purpose is to provide a switch device that can be manufactured at low cost and that can prevent two operators from being operated at the same time with a simple structure without using any special parts.

[Summary of the idea]

The present invention operates two sliding type switches by sliding each one of the operators provided so as to be slidable in a direction toward the other, and operating one of the two switches. The feature is that the spacing between the two operating elements is set to be equal to or slightly larger than the sliding distance of the operating elements.

It is installed so that it is substantially flush with the surface.

The upper surface of the first operator 24 of the first switch 18 is marked with the words "RESUME ACCEL," and the upper surface of the second operator 25 of the second switch 19 is marked with "SET/COAST." and "CRUISE" are attached to the push button 22 of the third switch 20.
``CANCEL'' is written on the top of the .

Next, the operation of the above configuration will be explained.

From the off state shown in Figures 1 and 2, the first
The operator 24 is connected to the top wall 1a of the switch case 1.
When the first contact holder 9 is slid in a direction approaching the second operator 25, that is, in the direction of arrow A, to the position shown by the two-dot chain line, the first contact holder 9 moves in the direction of arrow A through the recess 30 and the guide part 29. The side wall portion contacts the partition wall portion 1b, the contact 12 contacts the fixed contact 6, and the first switch 18 is closed. On the other hand, the ball 15 moves down along the inclined surface 16 while compressing the spring 14 against the elastic force of the spring 14. In this state, the side edge 24a of the first operator 24 is slightly spaced from the opposing side edge 25a of the second operator 25, and the second operator 25 is directed toward the opposite arrow A. It cannot be slid in any direction. When the biasing force of the first operator 24 in the direction of arrow A is removed, the ball 15 moves along the inclined surface 16 in the opposite direction of arrow A due to the elastic force of the spring 14, and as a result, the first contact The holder 9 is also slid in the opposite direction of arrow A, and the switch 18 is opened and the first operator 2
4 is also returned to the off position. Further, when the second operator 25 is slid in the direction opposite to the arrow A so as to be close to the first operator 24, the second switch 19 is closed in the same manner as described above, and in this state, the first switch 19 is closed. Sliding operation of the operator 24 in the direction of arrow A is not possible. Therefore, if the biasing force of the second operator 25 in the opposite direction of arrow A is removed, the second operator 25 returns to the off position. If the first and second controllers 2 are turned off from the off state,
4 and 25 simultaneously in the direction of arrow A and the direction opposite to arrow A, the first and second operators 24
and 25 is the side edge 24a at approximately the middle position.
and 25a come into contact and subsequent sliding operation is restricted, so the first and second switches 18 and 1
9 are kept open. Therefore, when the side edges 24a, 25a are shifted toward one of the operators from the intermediate position, the other switch is closed, but one switch is kept open and the first and second switches are closed. Switches 18 and 19 are never closed at the same time.

The distance between the side edges 24a and 25a of the first and second operators 24 and 25 is such that when one of the first or second operators 24 or 25 is operated, the first or second operator 24 or The strokes of the first and second manipulators 24 and 25 may be set so as to contact the other of the manipulators 25.

According to the above embodiment, the first and second operators 2
When one of the operators 4 and 25 is operated in a direction closer to the other operator, there is only a slight gap between the opposing sides of the side edges 24a and 25a of the first and second operators 24 and 25. Since the sliding operation of the other operator is restricted, simultaneous operation of the first and second operators 24 and 25 can be restricted without using any special parts, and the manufacturing cost can be reduced accordingly. .

[Effect of idea]

As is clear from the above explanation, the present invention is based on the first
and one of the first and second switches is actuated by sliding one of the second operators in a direction approaching the other, wherein the first and second operators are opposed to each other. Since the spacing is set to be equal to or slightly larger than the sliding distance of these operating elements, it is possible to prevent these two operating elements from being operated at the same time with a simple structure, and the effect is that it can be produced at a correspondingly low cost. play.
