PCB Based Membrane Keypads

A glass epoxy PCB, a hard-backed PCB, and a thin polyester layer coated with conductive silver make up a PCB based keypad. These two layers are separated by a spacer that features air vents for flawless switch operation. These keyboards come in tactile and non-tactile varieties, and they can be embossed or not. These keyboards can be constructed with built-in LEDS and can have LEDs for the backlighting. There are tactile, non-tactile, and capacitive switches for PCB based membrane keypad. Regarding construction, they are also available in single-sided, double-sided, or multilayered forms. These keypads offer a wide range of connectivity possibilities.
