At present, the common keycap materials on the market can be roughly divided into three types: hard PBT, ABS with high ductility, and POM with strong flexibility. The difference of these materials will affect the plastic performance of the keycap, but will it affect the feel? In the 84th and 85th issue of Computer King, the author used an instrument to test the elastic curve, and observed whether the process of pressing the keycap to the end of different materials was different. At that time, the conclusion was that the compression curve was not affected, and the output of the finger did not change. Therefore, when you feel the difference in feel, it comes from the feeling of the fingers touching different materials, and the different feedback force brought by the keycap hitting the bottom. The latter are more subjective feelings, and it is necessary to actually try to feel the difference.
