What is the reason why the silicone key feels bad?

Silicone keys, as the name implies, are key products made of silicone as raw materials. The elastic requirements of silicone keys are not known to many laymen. In fact, many people in the industry are not clear. The silicone key hand feeling in the industry refers to the paragraph feeling, also known as click value, which is the percentage of peak-valley value/peak value. In the production process, there are generally three situations that will cause the silicone key to feel bad.
The engineers of Mingzhen analyzed these three situations in detail as follows:
1. Silicone button elasticity
The elasticity or elasticity of silicone keys is in units of strength (g/g); Silicone keys with too high elasticity will be difficult to press, but due to the problem of usage habits, Europeans and Americans will differ from East Asians by about 100g. Generally, people refer to hand feeling as high elasticity, which is more difficult to press, while low elasticity is softer to press or will not rebound.
2, Silicone button surface hardness
Silicone keys are made of silica gel or silica gel after high temperature vulcanization molding. Due to the low hardness, the surface will be soft and affect the bad touch feeling. This kind of hand feeling can improve the hardness of the material. The degree of silicone raw materials on the market can be from 0 to 80 degrees, and we can adjust the hardness of different silicone to a certain hardness specified to meet the needs of customers.
3, paragraph sense
Generally, the click value is 40%-60%, and the bigger the feel, the better. However, if the click value is too large, it may cause problems such as no rebound, stuck keys, suction cups, short key life, etc. If the click value is too small, it will also cause the resilience of the silicone key to be too high and there is no paragraph feeling when pressed.
