Conductive Silver Ink Printing Tactile Metal Dome Switch For WIFI
Telecommunication Device
Benefits
Cost-Effective: Generally cheaper than many mechanical switch alternatives.
Easy Integration: Can be easily integrated into various electronic designs and
circuits.
Variety of Sizes and Shapes: Available in different sizes and shapes to fit specific design
requirements.
Key Features
Tactile Feedback: The switch provides a noticeable click or bump when pressed,
allowing users to feel the activation point. This feedback can
enhance user experience and help prevent accidental presses.
Metal Dome Construction: Typically made from a thin metal dome, these switches are often
mounted on a flexible circuit board or membrane. When pressed, the
dome collapses, completing the circuit.
Compact Size: Metal dome switches are compact, making them suitable for
applications where space is limited.
Durability: They are generally robust and can withstand a high number of
actuations, making them reliable for long-term use.
Low Profile: The low profile of these switches allows for sleek designs in
electronic devices.
Applications
Keyboards: Used in membrane keyboards for tactile feedback without the need
for mechanical switches.
Remote Controls: Commonly found in TV and audio device remotes.
Consumer Electronics: Used in devices like calculators, gaming controllers, and other
handheld devices.
Considerations
Limited Lifespan: While durable, they may not last as long as some mechanical
switches under heavy use.
Feel and Sound: The tactile feedback and sound may not suit all users, depending
on personal preference.
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
