Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a wiring board device for mounting a slide switch which has been improved for smooth operation of the slide switch.

Conventionally, in a slide switch that performs switching by sliding on a contact pattern provided on a board, when the slide switch is operated by sliding, the thickness of the wiring pattern connected to the contact pattern causes the wiring pattern to be connected to the slide switch. The problem was that the bottom got stuck and the slide operation could not be performed smoothly.

To explain this with reference to drawings, FIG. 1 is a diagram showing the configuration of a conductive pattern around a conventional contact pattern.

In the figure, 1 is a contact pattern, and a wiring pattern 2 is connected to this contact pattern 1.

The arrows in the figure indicate the sliding direction of the slide switch and the sliding position of a part of the sliding part provided at the bottom of the slide switch and slidingly in contact with the wiring board.

As shown in the figure, a portion of the sliding contact section crosses the wiring pattern 2 at points A and B.

Therefore, if the sliding means gets caught due to the thickness of the wiring pattern 2 at points A and B and the sliding operation cannot be performed smoothly, or if the sliding operation becomes difficult due to the number of times of use, the wiring pattern 2 at the points A and B may become stuck. There was a risk of the wire breaking.

The present invention solves the above-mentioned conventional drawbacks, and aims to provide a switch that allows smooth operation of a slide switch provided on a wiring board.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

Fig. 2 is a front cross-sectional view of one embodiment of the slide switch according to the present invention, Fig. 3 is a side cross-sectional view of Fig. 2, and Fig. 4 is an external view of the slide switch according to the present invention as seen from the bottom. show.

In this Figure 2.3.4, 3 is a knob for manually sliding the slide switch to turn it on and off, and the lower part of this knob 3 has a spring-like contact for switching. The metal part 4 is attached.

Knob 3 above. Hemispherical sliding means 6 are attached to the four corners of the bottom of the slide switch 5 provided with the metal contact portion 4 to form a sliding contact portion for smooth sliding of the slide switch 5.

Further, 7 is a printed circuit board, and on this printed circuit board 7 is provided a contact pattern 1 of copper foil that forms the contacts of the switch.

FIG. 5 is a configuration diagram of a conductive pattern around the contact pattern 1. As shown in FIG.

In this figure, the same parts as in FIG. 1 are designated by the same reference numerals.

As shown by the arrow in the figure, the sliding position of the sliding means 6 of the slide switch 5 is on the guide path 8 formed by the wiring pattern 2, a pattern extending from the wiring pattern 2, or another pattern. Therefore, it is possible to smoothly slide the slide switch 5 on the guide path without getting caught on the wiring pattern 2 as in the conventional case.

As explained above, according to the present invention, a guide path made of a conductive pattern is formed in at least a part of the wiring board other than the contact pattern on which the slide switch slides.
This allows smooth operation of the slide switch.
