テル。(Prior art) The elastic key part that forms the diaphragm part of this type of conventional key switch is mainly molded from silicone rubber, but this is due to the reaction force of the restoring force of the diaphragm part that cushions the key top. Due to the low 4-shot elastic modulus and weak bending fatigue resistance, it has become clear that the key top returns slowly, which is a problem with the material. This is left to the delicate adjustment design of the setting angle of the diaphragm part and the C thickness ratio, but since it is not possible to obtain a good lick feel with strong anti-conventional elasticity, silicone rubber is much better. A thermoplastic polyester with high tensile modulus, excellent bending fatigue resistance, and excellent moisture, oil, and chemical resistance.

欠点が発見されるに至った。Made of elastomer resin, the elasticity of the diaphragm part of the elastic key part is greatly strengthened, so that the return of the flip 1 is extremely fast and good, and the switch performance is improved.
In order to further strengthen the elasticity of the diaphragm, we made the back side of the diaphragm thicker and curved, and added rib reinforcement to the flamm to significantly strengthen the elasticity and improve the elasticity when pressing the key top. A key switch designed to ensure a reliable click feel was filed as a prior invention in Japanese Patent Application No. 63-98764 (Japanese Patent Application Laid-Open No. 1993-98764) by the same inventor as the present inventor.
No. 272018) was developed, but since the polyester and elastomer resins are harder materials than silicone rubber, experiments have shown that the elastic modulus of the diaphragm can be significantly strengthened by forming reinforcing lips and thickening the back curve. On the contrary, it was discovered that when the key tops are pressed, the clicking sensation of the diamond and plum sections becomes stronger, resulting in a very hard and heavy feeling of suppression.

キースイッチを提供することを目的とするものである。(Problems to be Solved by the Present Invention) Therefore, the present invention has been developed by molding the thermoplastic polyester or nidistomer resin according to the prior invention, by providing a reinforcing rib in the diaphragm part, and by making the periphery of the back side curved and thick. The plum part of the key switch has a strengthened elastic modulus, and the click feeling is strengthened accordingly.
The paradoxical drawback that the key tops are very difficult to press down can be easily solved by providing an adjustment window hole in the diaphragm part, and the diaphragm part of the prior invention has a very high elastic modulus. The object of the present invention is to provide a highly demanded key switch equipped with an elastic key part that provides a good click feeling and is light and easy to press down on the key top.

実に備わることになる。In a key switch made of resin molded from elastomer, the entire periphery of the back side of the diaphragm part of the key part is rounded, and the flam part is provided with ribs, and the adjustment window circular hole is symmetrical with respect to the diaphragm part. It is characterized by forming a required number of perforations to form an elastic key part.
A round or square hole with an adjustment window of the required size is attached to the flam part of the key switch, in which the diaphragm part is reinforced and an elastic key part with a thick curve around the back side of the flam part is attached. By arranging the required number of holes symmetrically,
The silicone rubber is also strong and has a remarkable elasticity, giving a strong click feeling.The top pressure is hard and heavy, and the diaphragm part is hard and heavy, and its hardness is adjusted through the adjustment window hole, making it light and comfortable. This will definitely provide a lick feel and a suppressed feel to the key tops.
