Conductive Silver Ink Printing Led Membrane Switches For WIFI Telecommunication Device

Conductive Silver Ink Printing Led Membrane Switches For WIFI Telecommunication Device

Features

1. Membrane Technology: These switches are typically constructed with multiple layers, including a graphic overlay, spacer layer, and conductive layer, allowing for a durable and flexible design.

2. Illumination: LEDs can be incorporated under the switch surface to provide visual feedback when a button is pressed or to indicate the status of a device.

3. Custom Designs: They can be customized in terms of shape, size, color, and graphics, making them suitable for various applications.

4. Touch Sensitivity: The switches are activated by pressing the surface, which can allow for a seamless and modern design.

5. Sealed Interfaces: Many LED membrane switches are designed to be waterproof and dustproof, making them ideal for industrial and outdoor applications.

Applications

• Consumer Electronics: Used in devices like remote controls and home appliances.
• Medical Devices: Common in medical equipment where a clean and easy-to-use interface is crucial.
• Industrial Controls: Employed in machinery and equipment where robust control interfaces are needed.
• Automotive: Used in dashboards and control panels for various vehicle functions.

Advantages

• Space-Saving: Their slim profile allows for compact designs.
• Durability: Resistant to wear and tear, suitable for high-use environments.
• Aesthetic Appeal: Offers a modern look with customizable designs.

 
 Specification:

1)Material (for front or face overlay)

Polyester:

1.Highly versatile for embossing

2.Highly resistant to chemicals

3.Better durability

4.For internal and external use, UV resistance

Polycarbonate:

1.Different surface(Glossy, Matt) and thickness(From 0.12mm~2mm)

2. cost-effective in price

3.For internal and external use

2) Embossing

Rim embossing/pillow embossing/dimple embossing

Graphic overlays can be embossed in order to insert domes/LED, leave space for mechanical keys/LED and provide tactile indications and better tactile feeling.

3)Windows(for display function)

1. print different colors windows, As transparent grey/Red/green window for display

2. Clear/Transparent window for LCD display

2. Matt/semi-transparent window for LED

4)Keys/buttons

Tactile keys---with metal dome or poly dome

Non-tactile--silver printing dots with flat key

5) Embeded LEDs

Small, brilliant lights only about 0.02’’ in height. Avaliable in several vibrant colors.

LED colors: white, yellow, orange, green, red, or double colors LED.

6)Cable

It is an extension of the printed circuit and is used to communicate with your device.

7)Types of connector

1.Zero insertion force (ZIF) connector; 2.Female connector; 3.male connector

8) EMI / RFI / ESD Shielding

use an aluminum foil shielding / a clear ITO electrical conductive polyester

9)Adhesive

mostly used are 3M-double-side glue

10)Backplate-

in aluminum, polycarbonate, acrylic, PCB
