LED Backlight Screen Printing Rubber Membrane Keyboard With Transparent Window

Product Specification

LED Backlight Screen Printing Rubber Membrane Keyboard With Transparent Window Display

Features

1. Construction: Composed of a thin, flexible membrane layer made of rubber or silicone, which acts as the key switch.
2. Key Press: When a key is pressed, the rubber dome collapses and makes contact with a circuit board beneath, registering the keystroke.
3. Sealed Design: Often designed to be spill-resistant and dust-proof, making them suitable for various environments.

Advantages

• Cost-Effective: Generally cheaper to produce, making them affordable options for basic keyboards.
• Quiet Operation: Rubber dome switches are typically quieter than mechanical switches, which can be beneficial in shared spaces.
• Durability: Although they may not last as long as mechanical keyboards, rubber membrane keyboards can withstand moderate use.

Disadvantages

• Typing Feel: Many users find the typing experience less satisfying compared to mechanical keyboards, as the feedback can feel mushy.
• Key Response: The actuation may not be as precise, which can affect typing accuracy for some users.
• Limited Lifespan: Rubber domes can wear out over time, leading to reduced responsiveness.

Use Cases

Rubber membrane keyboards are commonly found in:

• Laptops: Many laptops use this technology due to space constraints and cost considerations.
• Office Keyboards: Ideal for environments where noise and cost are concerns.
• Remote Controls and Other Devices: Frequently used in devices that require simple input without complex features.

 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
