Legend Printing Electronical Key Membrane Switch Customizable Design

Legend Printing Electronical Key Membrane Switch Customizable Design

Components

1. Overlay: The top layer, usually made of a flexible material like polyester or polycarbonate, which has printed graphics or symbols.
2. Spacer Layer: This layer separates the top and bottom circuits, ensuring that the switch does not activate until pressed.
3. Circuit Layer: Made of a conductive material, this layer contains printed circuits that complete the electrical connection when the switch is pressed.

Features

• Sealed Design: Many membrane switches are sealed to protect against dust, moisture, and other environmental factors.
• Customizable: They can be easily customized in terms of size, shape, color, and graphics.
• Thin Profile: Membrane switches are typically very thin, making them suitable for applications with space constraints.

Applications

• Consumer Electronics: Remote controls, microwaves, and other household appliances.
• Industrial Equipment: Control panels for machinery and equipment.
• Medical Devices: User interfaces for medical monitoring and diagnostic tools.

Advantages

• Durability: Resistant to wear and tear, ideal for high-usage environments.
• Cost-Effective: Generally less expensive than other types of switches.
• Easy to Clean: The smooth surface makes them easy to wipe down.

Disadvantages

• Limited Tactile Feedback: They often lack the physical feedback of mechanical switches.
• Potential Wear Over Time: The graphics on overlays can wear off with extensive use.

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

Applications:
Control panels for household appliances, office equipment, and industrial machinery
Keypads and control interfaces for consumer electronics, medical devices, and automotive systems
Signage and user interfaces for kiosks, vending machines, and other self-service devices
Dashboard controls and instrumentation for vehicles, boats, and heavy equipment
Touchpads and control surfaces for various types of equipment and devices

Advantages:
Customizable design for branding, functionality, and visual appeal
Durable and long-lasting, with resistance to wear, moisture, and environmental factors
Cost-effective solution for producing high-quality, custom control interfaces
Versatile in terms of shape, size, and integration with the overall product design
