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.
PVC membrane panel is stable in acid, alkali and salts. The advantages are excellent wearability, burning resistance, noise elimination, shock absorption and good electrical insulation. The panel of Haiwen can be customized based on customer’s design such as button icons, colors etc. Selecting transparent PVC to screen print the overlay appears elegant and colorful. Buttons are embossed with tactile. The articles are widely used for control keypads for home applications. The rear adhesive adopt 3M9448.
