Custom Electronic Membrane Switch Keypad Waterproof Flexible With Embossed Dome
It is a Keypad with flexible tail with/ without connector as per design and application. The Keys are mounted on multi layers of punched flaxible polymer sheets (typically polyester) sandwiched together. Circuits are silk-screened with conductive silver ink on both the top and bottom membrane layers. Low cost , reliable Keypads, alternative Key-life exceeds - - 5 million
Keystrokes, also lighter than a PCB, Flaxible circuits allow Product from which is not possible with rigid PCB. Rim & Pillow Type Emboss available on demand . Male Female Clincher connector are used.

Membrane switches can be used in a great variety of low-voltage applications, from microprocessor-based systems to data entry pads and digital control panels. While thin and flexible, these screen-printed circuits are also rugged and reliable, and free from the common failures associated with mechanical parts. Membrane switches are flexible and must be mounted on a rigid backer panel, plastic, metal or a printed circuit board.
