Color matching and selection of membrane switch

Color matching and selection of membrane switch

The color of the membrane switch panel layer is printed on the reverse side of the membrane by screen printing with special ink.

In terms of color selection, first, consider the nature of the whole machine. For example, measuring instruments should be solemn and elegant, and the basic color of the panel should coordinate with the chassis. Civil products focus on bright and active, which can play a role in rendering and adjusting their environment. Second, consider the working environment of the whole machine. For example, soft, quiet and clear colors should be selected for electronic medical products. Dark colors are preferred for complete machines used in harsh environments. Third, pay attention to the scientific nature of color. Different colors have different wavelengths, and their impressions and positions in the human retina are also different. For example, red has a longer light wave in the visible light spectrum and is the deepest in the position where the retina is formed. It is easy to attract people's attention and excitement. It is suitable for critical marking in the instrument panel. The green wavelength is in the middle, and the human vision has the strongest resolution. It is suitable for subtle marks, figures or graphic curves. In many modern digital instruments or intelligent instruments, they are often used or used as digital or graphic display. In the window of the display part, a layer of colored transparent paint should be printed, which not only conceals the outline of the display element, but also improves the appearance of the panel. However, the color of this layer of transparent colored paint should be consistent with the color of the light-emitting element, so that its wavelength matches, so that the luminous characters can be clearer.
