LCD Membrane Switch With 1.25mm Pitch And Screen Printing Silver
Conductive Circuit Customizable For Electronic Applications
It seems like you're interested in a customizable LCD membrane
switch with specific features. Here’s a brief overview of what to
consider for such a product:
Key Features to Consider
Screen Printing:
- This technique allows for high-quality graphics and durability,
ensuring the design lasts over time.
Applications:
- Ideal for various electronic devices such as appliances, medical
devices, and consumer electronics.
Pitch:
- A 1.25mm pitch indicates the spacing between the conductive traces,
allowing for compact designs.
Conductive Circuit:
- Silver conductive ink is commonly used for its excellent
conductivity and reliability.
Customization:
- Consider options for layout design, button shapes, and sizes, as
well as any specific graphics or branding you want on the switch.
Additional Considerations
- Tactile Feedback: Decide if you need tactile feedback for user interaction.
- Testing: Conduct thorough testing to ensure functionality and durability.
- Environmental Resistance: Ensure the switch can withstand any environmental factors
relevant to your application, like moisture or temperature
variations.
Specification:
Types of connector
1.Zero insertion force (ZIF) connector; 2.Female connector; 3.male
connector
EMI / RFI / ESD Shielding
use an aluminum foil shielding / a clear ITO electrical conductive
polyester
Adhesive
mostly used are 3M-double-side glue
Backplate-
in aluminum, polycarbonate, acrylic, PCB
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
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
Keys/buttons
Tactile keys---with metal dome or poly dome
Non-tactile--silver printing dots with flat key
Polycarbonate:
1.Different surface(Glossy, Matt) and thickness(From 0.12mm~2mm)
2. cost-effective in price
3.For internal and external use
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.
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.
Cable
It is an extension of the printed circuit and is used to
communicate with your device.
