LED Backlight Screen Printing Mechanical Keyboard Switches With Transparent Window Display

LED Backlight Screen Printing Mechanical Keyboard Switches With Transparent Window Display

1. Types of Mechanical Switches

• Linear Switches:

  • Characteristics: Smooth keypress with no tactile bump.
  • Examples: Cherry MX Red, Black, Gateron Red.
  • Usage: Preferred for gaming due to fast key presses.

• Tactile Switches:

  • Characteristics: A noticeable bump at the actuation point.
  • Examples: Cherry MX Brown, Gateron Brown.
  • Usage: Good for typing and gaming, offering feedback without being too loud.

• Clicky Switches:

  • Characteristics: Tactile bump with an audible click sound.
  • Examples: Cherry MX Blue, Green, Gateron Blue.
  • Usage: Favored by typists who enjoy audible feedback but can be noisy.

2. Switch Brands

• Cherry: The original manufacturer of mechanical switches, known for reliability.
• Gateron: Offers smooth operation and is often considered a budget-friendly alternative to Cherry.
• Kailh: Known for a wide variety of switch types and styles.
• Razer: Custom switches made for gaming, often featuring unique designs.

3. Factors to Consider

• Actuation Force: The amount of force required to press a key. Lighter switches (e.g., Red) require less force, while heavier switches (e.g., Black) require more.
• Travel Distance: The distance a key travels before it's actuated. Most switches have a travel distance of around 4mm.
• Durability: Mechanical switches can last for tens of millions of keystrokes, making them more durable than membrane switches.

4. Customization

Many mechanical keyboards allow for switch swapping, enabling users to customize their typing experience. Hot-swappable keyboards let you change switches without soldering.

5. Sound Profile

Consider the acoustic properties of the switches, as this can impact the typing experience, especially in shared spaces.

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
