Everlight 0603 red-green Bi-color LED welded on the lower circuit layer consists of the membrane keypad with buttons and LED window embossed. The product are mainly used as industrial control keypad, for it’s tactile keys and stability of function. Selecting Autotype F150 matte PET to make the overlay appears elegant and colorful. Also, keypad can be customized based on customer’s design such as button icons, colors etc. The circuits are printed with Acheson ED-478ss silver paste, so that it can be low resistance and function well. Item HW-16041508 with strong function is able to weld with colorful LEDs. Besides, the product including electrostatic shielding protect the function from static.
Membrane switch flexible polycarbonate or polyester film printed with conductive paste made of the switch contact circuit is a contact switch.
Membrane switch 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.
