Overview

[Features]

1. The shrapnel can be processed on PET adhesive material (Metal array). Its structure is to carry a metal film on the adhesive surface covering the tape, and use the metal film to short-circuit the patterns on the substrate (rigid or flexible), with excellent fitting and stable electrical characteristics.

2. It can significantly reduce the thickness of the switch unit, making it convenient for customers to use and install.

3. Installing MetaldomeSwitch backlight board on the covering tape has a wide variety of products, which helps to further achieve thinness in the device.

[Main use]

1. Remote control, operating switch for small, portable AV devices.

2. Input button switches for mobile phones, smartphones, PDAs, etc.
