Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device for switching a circuit by operating an operating body, for example, a two-way switch device, and more particularly to a switch device capable of obtaining a smooth switching operation.

[0002]

2. Description of the Related Art Generally, a switch device of this type includes a case, a circuit board provided in the case, a slider slidably mounted on the circuit board, and the slider at least at a first position. And an operating body that slides between a second position, a switching mechanism that holds the state in which the slider is slid by the operation of the operating body and is switched to the first position or the second position, and the slider. And a contact which is mounted on the circuit board and switches the circuit as the slider slides. When the operating body is operated, the slider slides to switch from the first position to the second position or from the second position to the first position, and as the slider slides, the contacts move on the circuit board to form a circuit. Switch. In the above switch device, the slider and the circuit board are provided so that the slider slides smoothly and the contacts move smoothly, that is, the contact side moving contact and the circuit board side fixed contact can be smoothly switched. There is a slight gap between them (for example, about 0.2 m
A gap of about m) is provided. In the slide stroke of the slider of the above-mentioned switch device, a neutral position is provided between the first position and the second position, and the slider is moved from the neutral position to the first position, conversely from the first position to the neutral position, Alternatively, the neutral position may be switched to the second position, and conversely, the second position may be switched to the neutral position. Such a switch device is an electric remote control type door mirror, and is a so-called two-way changeover switch for switching between a tilting operation of the mirror surface of the left door mirror up and down and left and right and a tilting operation of the mirror surface of the right door mirror up and down and left and right. It is used for equipment.

[0003]

However, the above-mentioned conventional switch device uses a slider in which the portion on the operating body side equipped with the operating body and the portion on the contact side equipped with the contact are integrated. For this reason, in the above-mentioned slider, the distance from the force point on the operation body side portion to the action point on the contact side portion is long, and the length of the lever arm with the switching mechanism as a fulcrum is long. As a result, in the above-described conventional switch device, when the switch switching operation (slider sliding operation), the force of sliding the slider acts on the contact with a large force on the contact by the lever mechanism as a fulcrum. Further, due to the slight gap between the slider and the circuit board, the slider tilts with the switching mechanism as a fulcrum, but the tilt of the slider becomes large. Therefore, the conventional switching device has a problem that a smooth switching operation cannot be obtained.

An object of the present invention is to provide a switch device which can obtain a smooth switching operation.

[0005]

According to the present invention, a slider is divided into an operating body side portion and a contact side portion, and an inner case is provided between the operating body side portion and the contact side portion. The operation body side portion is arranged between the case and the inner case, the contact side portion is arranged between the circuit board and the inner case, and the operation body side portion and the contact side portion are engaged with each other through the inner case. It is characterized in that they are connected to each other by a coupling means.

[0006]

According to the present invention, when the operating body is operated, the slider slides, the contacts move on the circuit board accordingly, and the circuit is switched. At this time, the slider is attached to the operation body side portion and the contact side portion.
Since it is divided, the distance from the force point of the operating body to the point of action of the inner case can be made small on the operating body side part, and the length of the lever arm can be made small with the switching mechanism as the fulcrum. it can. As a result, the force of sliding the slider, which acts on the inner case with the switching mechanism as a fulcrum by the lever principle, can be reduced, and the tilt with the switching mechanism on the operating body side as a fulcrum can be used. Can be small. On the other hand, the operating force of the operating body side portion is transmitted to the contact side portion by the engaging means, but the inclination of the operating body side portion is not transmitted to the contact side portion, so that the contact side portion can move smoothly on the circuit board. Therefore, the switching operation between the moving contact on the contact side and the fixed contact on the circuit board side is smooth. That is, a smooth switching operation can be obtained.
