Implement the chip LED below or to the side for illumination! A membrane switch that enhances design and visibility.
The "Character Illuminated Type" membrane switch is an advanced version of the LED-implemented type, designed for cases where you want the characters or logos on the keys of the membrane switch to glow overall. It uses chip LEDs mounted below or to the side to provide illumination. While there are limitations on the width and pitch of the illuminated areas, this type has become increasingly popular among customers in recent years due to its enhanced design and visibility, and it is used in devices operated in dark places such as movie theaters. *For more details, please refer to the PDF document or feel free to contact us.*

<Case Study> Control Panel for Video Equipment Used in Movie Theaters This was produced at the request of a manufacturer of audio-related equipment. They requested that it be easy to operate and visible even in dark environments, so we created a membrane switch with illuminated key characters. We have developed a unique method to diffuse the light from chip LEDs, ensuring that there are no inconsistencies in the illumination of the characters. Furthermore, to enhance visibility, they requested the illumination color to be in two colors, so we used three single-color LEDs in white, red, and green to represent various states instead of indicators. To date, we have shipped around 5,000 units and received high praise.
