Capacitive switch

The main feature of the capacitive switch is that the keypad area can be printed with transparent conductive ink,which not only can achieve the keypad control function,but also fully present the display effect combination with backlight technology.

Flexible printed circuit (FPC)

Flexible printed circuit also known as flex circuit, is a technology of making a highly-stable and flexible circuitry using flexible plastic substrates such as polyimide (PI) or Polyester (PET). FPC's flexibility and strong signal quality ensure reliability and ease of control; and its size and weight reduction makes it ideal for three-dimensional assembly and installation. It has been widely used in electronics and communications industries.

Dome array

Dome arrays can be part of a membrane switch assembly, with the domes positioned on a flexible printed circuit or on a printed circuit board. Walico provides a variety of dome diameters that can suit your specific product design. Its price–performance ratio is much higher than open arrays assembled independently.

Electroluminescence (EL)

Electroluminescence (EL) is a backlighting technology that works by sending an electric current through phosphorous which then emits light when charged. It is one of the best backlighting options for providing even lighting across a large area. Similar to light guide films and fiber optics, EL can control the colors and light intensity via the printed overlay that covers the lit area. It is light, thin, flexible, and very little heat generated. It has high shock absorbing ability and long service life. It is commonly found in communication products, electronics, toys…etc.
