Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a slide switch used in electrical products.

There have been waterproof switches in the past, but they are made by covering the entire switch with something like a rubber sheet, which makes them unsightly and bulky, making them unsuitable for small electrical appliances.

An object of the present invention is to obtain a waterproof slide switch structure suitable for small and thin electrical products.

The gist of the invention is as described in the claims.

Next, the present invention will be explained using examples.

FIG. 1 is a sectional view of a slide switch showing an embodiment of the present invention, which slides in left and right directions.

The switch 1 consists of a switch body 2 and a knob portion, and a spring 4 is secured to the lower part of the switch body 2 by heat caulking at a portion 5. The housing 6 has an open lower portion for exposing the knob 6 to the outside and a groove 9 for housing the annular elastic member 8. The annular elastic member 8 is arranged so as to surround the opening, and has a thickness slightly larger than the depth of the groove 9).
Uzi: It is held between /gu 6 and switch 1. The spring 4 has its free end in contact with the contact plate 10. On the contact plate 10,
Although not shown, contacts are formed by, for example, a printing method. It is desirable that the spring 4 has a plurality of free ends, especially four, for stability. The spring 4 may be coupled by a well-known coupling method such as adhesion or screwing, or may be simply by aligning a hole in the spring 4 with a protrusion 5 as shown in the figure.

FIG. 2 is a view of the switch 10 in which the spring 4 is combined as seen from the direction of the arrow 11, and the cross-sectional shape of the switch body 2 is U-shaped. The spring 4 is housed in the U-shaped space, and the free end 12.13 protrudes from the lower surface 14.15 of the switch body.

In the slide switch structure according to the present invention as described above, the elasticity of the spring 4 as a conductive member is not only used to obtain contact pressure, but also has the role of compressing the annular elastic member 8 and ensuring waterproofness.

Since the spring 4 absorbs dimensional errors in the thickness direction of each component, the amount of compression of the annular elastic member can be kept to the minimum required for waterproofing. Therefore, the annular elastic member can be extremely thin, and in a structure with a storage groove, the depth of this groove can also be extremely shallow.Thereby, the entire product can be made thin. This is a very useful structure for watches and composite products that seek to be as thin as 0.01 mm, and is invisible from the outside and has a luxurious feel.

In addition, in the case of a switch having a U-shaped cross section, even if the knob part 6 receives a downward force, the bottom surface 14,15 of the switch hits the contact plate, etc.), and the housing 6 and the switch body 2 It is possible to minimize the gap, ensure waterproof performance, and achieve a more desirable structure.

As a result, a waterproof structure with an excellent appearance can be obtained particularly in portable spiritual products such as small radios that are strongly required to be small and thin.

Note that the annular elastic member 8 may be housed in a groove provided in the switch 1, and the groove may not be provided in both the double flaps 5.
