       Membrane keypad flexible polycarbonate or polyester film printed with conductive paste made of the switch contact circuit is a contact switch. 

       Membrane keypad has the advantage of the whole flat, thin shape, quality, small, dust-proof, good, good water resistance, is a semi-enclosed structure. In addition, the panel design, and great freedom of choice of colors. Positive range of applications of desktop computers, copiers, fax machines, toys, square computer, word processor and other areas of expansion.

        Metal domes added to the membrane keypad provide the upper circuit layer. That contributes the keys to visual, audible, and tactile feedback.
