First of all, the appearance should be good, and the appearance should be flat and shiny. No mechanical operation, scratches, inclusions, stains and other appearance defects. Secondly, the weather resistance is better. Under certain natural environmental conditions, it will not be deformed, cracked, aged, or discolored. Good chemical resistance, the panel layer will have different chemicals, but it must have a certain resistance to most common chemicals, such as alcohols, ethers, and mineral oils.
Common membrane switch keys only use color to express the position, shape and size of the key body. Therefore, the accuracy of the operation can only be recognized by the operator's vision. Since there is no appropriate feedback information to indicate whether the finger is pressed in the effective range of the switch to make the switch act, thus affecting the confidence in the monitoring of the whole machine and the speed of operation.
However, the bulge of the keypad of the membrane switch further enhances the visual effect, not only can accurately specify the range of the key body, improve the recognition speed, make the operator's sense of touch more sensitive, but also enhance the decorative effect of the product appearance. Therefore, the button bulge is more and more welcomed by users and manufacturers.
