Definitions
- the present invention relates to a waterproof and dustproof switch that can be used as a power switch in an electronic device such as an electronic book terminal or a mobile phone, and can prevent entry of water droplets, dust, dust, or the like into the switch mechanism or the electronic device.
- a waterproof switch previously filed by the present applicant is known as a switch having the above characteristics (see Patent Document 1 below).
- This waterproof switch has a switch body portion housed in a switch case, and the switch case has a two-layer structure including a waterproof cover and a case body molded in two colors on its outer surface.
- a part of the waterproof cover protrudes in a dome shape on the outer surface of the case body, and the knob of the switch main body is disposed inside the dome. Therefore, according to this waterproof switch, since the knob of the switch body is completely covered by the dome that is a part of the waterproof cover, water that enters the switch case from around the knob can be prevented.
- the dome that is a part of the waterproof cover is configured to expand and contract integrally with the knob when the knob is pressed.
- the thickness of the resin constituting the dome must be formed thinner than other waterproof cover portions (see FIG. 1 and FIG. 7 of Patent Document 1). Therefore, if the pressing operation of the knob is repeatedly performed, the thin part of the dome has a sag or crack in the resin, and there is a problem that a stable switch operation cannot be obtained.
- the present invention has been made to solve such a problem, and the object of the present invention is to reliably prevent intrusion of water droplets and dust into the switch case and to improve durability. It is an object of the present invention to provide a waterproof and dustproof switch that can be improved to ensure stable switch operation over a long period of time.

- a reinforcing rib that is integral with or separate from the case main body is provided in a portion that receives the above action.
- the switch case may employ a configuration in which a leaf spring is formed by the top plate of the case body and the reinforcing rib inclined with respect to the top plate. .
- the switch case may be disposed at a position where the reinforcing rib presses the operating body of the switch mechanism when an external force is applied to the cover.
- the switch case may employ a configuration in which the case body is made of polyamide resin and the cover is made of silicone rubber.
- the switch mechanism may be a lever switch that switches contacts by tilting the lever.
- the case main body and the cover are integrated by two-color molding, and the cover is in close contact with the case main body so that the switch mechanism is completely sealed. This prevents the intrusion of water droplets and dust, and can reliably protect the switch mechanism. Also, because the cover is provided with reinforcing ribs that are integral with or separate from the case body, the cover is free from sagging or cracking even after repeated use, and its shape retention is good. In addition to being able to be maintained, there is an effect that it is excellent in durability and can realize a smooth and stable operation over a long period of time.
