Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide switch.

[0002]

2. Description of the Related Art There is a demand for waterproofness in small electronic devices such as paging receivers, and accordingly, waterproofness of switches is also required. As such a switch, a push-type switch is generally widely used. However, the push-type switch has a problem that it is difficult to determine what state the small electronic device is set to. For this reason, recently, there has been a strong demand for a waterproof slide switch whose set state can be easily determined.

An example of such a waterproof slide switch is shown in FIGS. 7 (a) and 7 (b). This slide switch includes a slide operator 3 that slides in the storage recess 2 provided on the upper surface of the device case 1 toward the front and back of the drawing, and a rotary shaft 5 in a through hole 4 provided in the center of the storage recess 2. Is composed of a rotating body 7 rotatably attached through a waterproof ring 6, and a pair of electrode plates 8 and 9 arranged in the equipment case 1 with the lower outer periphery of the rotating shaft 5 sandwiched therebetween. There is. In this case, the rotating body 7 is provided with the rotating plate 10 on the upper end of the rotating shaft 5, and the connecting pin 11 is erected at an eccentric position on the upper surface of the rotating plate 10, and the connecting pin 11 is inside the slide operator 3. It has a structure in which it is movably inserted into a connecting groove 12 which is formed in a slender shape on the lower surface in the left-right direction orthogonal to the sliding direction. Further, the pair of electrode plates 8 and 9 are sandwiched by the pair of electrode plates 8 and 9 on the lower outer peripheral surface of the rotating shaft 5.
A cam projection 13 is provided to push the 9 apart and separate it. The pair of electrode plates 8 and 9 are bent in a V shape in the direction in which the tip portion 8a of the one electrode plate 8 approaches the other electrode plate 9, and the pair of electrode plates 8 and 9 are The tip portion 8a of one electrode plate 8 comes into contact with the other electrode plate 9 when it is in contact with only the outer peripheral surface of the rotating shaft 5.

In this slide switch, when the slide operator 3 is slid in the front-back direction of the paper, the connecting groove 12 of the slide operator 3 is moved in parallel in the same direction, so that the connecting pin 11 of the rotating body 7 is moved. Moves in the connecting groove 12 while swiveling around the rotating shaft 5, whereby the rotating body 7
Rotates about the rotary shaft 5, and the rotary shaft 5 rotates with this rotation.
The cam projection 13 provided on the outer periphery of the lower part of the gyro rotates between the pair of electrode plates 8 and 9. When the cam projection 13 comes into contact with either of the pair of electrode plates 8 and 9, the electrode plates 8 and 9 are spread by the cam projection 13, so that the tip end portion 8a of the one electrode plate 8 and the other electrode plate 9
Are separated from each other, the switch is turned off, and conversely, when the cam projection 13 is separated from the pair of electrode plates 8 and 9, the pair of electrode plates 8 and 9 are close to each other, and the tip portion 8a of one electrode plate 8 is
And the other electrode plate 9 come into contact with each other, and the switch is turned on. Thus, in this slide switch, the reciprocating motion of the slide operator 3 is converted into the rotary motion of the rotating body 7,
Since the electrode plates 8 and 9 are brought into contact with and separated from each other by the rotating motion of the rotating body 7, the waterproofness can be secured by providing the rotating shaft 5 of the rotating body 7 with the waterproof ring.

[0005]

However, in such a conventional slide switch, although the waterproof property can be ensured by the waterproof ring, the reciprocating motion of the slide operator 3 is converted into the rotary motion of the rotating body 7. Because it is a structure,
There is a problem that the structure is complicated, assembly workability is poor, and the entire switch becomes thick. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a slide switch that has a simple structure, can be made thin, and can ensure waterproofness.

[0006]

In order to achieve the above object, the present invention provides a slide operator which is slidably accommodated in a switch accommodating portion of an equipment case and has a pressing portion at the lower portion, and a lower portion of the switch accommodating portion. A contact sheet which is attached in close contact with and is pressed by the pressing portion of the slide operator, and the contact sheet is a film in a state in which a pair of electrodes provided on the opposing surfaces of the film are separated and opposed to each other so that they can be contacted and separated. It is formed in a structure in which is bonded with an adhesive. In this case, it is preferable that the contact sheet has a structure in which a pair of electrodes corresponding to one surface of a film is formed, the film is bent to make the pair of electrodes face each other, and the films are bonded in this state.

[0007]

According to the present invention, since the sliding operation element is slidably accommodated in the switch accommodating portion in which the contact sheet is attached to the lower portion, the structure is simpler and thinner than the conventional one. At the same time, the contact sheet has a structure in which the films are bonded together with an adhesive in a state in which a pair of electrodes provided on the opposite surfaces of the film are separated and opposed to each other so that they can be contacted and separated.
Since the contact sheet is attached to the lower part of the switch housing in close contact, the waterproofness of the entire switch can be ensured. In this case, as described in claim 2, the contact sheet forms a pair of electrodes corresponding to one surface of one film, the film is bent to make the pair of electrodes face each other, and the film is bonded in this state. If formed, the contact sheet can be easily manufactured and a low-priced one can be obtained.
