Waterproof/UV Resistance Electronic Membrane Keypad With LED And Lcd Window
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. The switch can performance well in high temperature environment. The product are mainly used as control keypad for medical equipment. Also, keypad of Haiwen can be customized based on customer’s design such as button icons, colors etc. Selecting Autotype F150 matte PET to screen print the overlay appears elegant and colorful. The circuits are made of silver paste, so that it can be low resistance and function well. The rear adhesive is 3M 468.
