LED membrane switch
Product description
SMD (Surface-Mount-Device) LED diode is a widely-used illuminant. A single LED can light up an area of 4 sq.cm. A bigger panel needs more LEDs. We can apply any common LED to the panel. Also, we can do customization for our customers for some special LEDs.
Features

1. Enrich the indicative features of the panel
2. Simplified circuitry design
 

Metal dome arrays provide good tactile sensation. A metal dome array is a thin PET sheet with metal domes used on PCB board as buttons. When being pressed, the center of a metal dome contacts the circuit loop and let electric current go through. Metal dome membrane switches are used in cell phones, remote controls, CD/VCD/DVD, MP3/MP4, radios, digital cameras, video game controllers, microwaves, automobile dash boards, telescopes, toys, etc. Compared with PET membrane switches, metal dome switches have better tactile sensation and longer working life.

Features
1. 1 million presses working life
2. Good tactile sensation
3. Short development period
4. Can be easily modified according to changing market needs because it's: light & small; no need for additional weld

We can do customized design according to customers' demands.
We have four different types of metal dome arrays:
1. Single-layer; 2. Double-layer; 3. EMI print; 4. Contain EMI/rubber adhesive
