    A membrane s witch typically has 4 or more layers. The top layer of a membrane switch is the graphic interface between the user and the machine. The another critical layer is a printed circuit. This can also be a flex circuit made of copper and polyimide material. The layers are normally assembled using pressure-sensitive adhesives although inexpensive designs can be held together by other mechanical means such as a keyboard housing. Contact between two traces can be made through a printed shorting pad or through a metal dome that stands on legs.

    Many hand held equipment use LEDs for backlight. And we can design and assemble LEDs inside membrane switch. It would save lots of space and cost. Membrane switch with LEDs is the economical solution for switch backlighting. We can design LEDs for backlight buttons, symbols or icons. It would only need DC 3V to drive a LED, the best way to save energy in the project design. We can combine LEDs with light guide film, it could backlight the entire surface, this could increase the flexibility of design. With the design of water proof structure, membrane switch with LEDs can be installed in the outdoor equipment.

    This membrane switch is made for the control system of medical equipment. The structure is designed for IP68 degree. The operator can clean the surface of membrane switch easily, any liquid or alcohol won't seep into the membrane switch and damage circuit function of switch. If the operators need to use the medical equipment in dark room, there are some features of this membrane switch that help operators included LED light and embossing on the switches. Not only LED light can be installed in membrane switches, also light guide film with side light LED. Using light guide film as back light, the light could spread through whole membrane switch. Operators can easily find the location of button by embossed shape on the surface. On the end of cable, we use pitch 2.54mm female connector, customers can install the membrane switch very quickly.
