Customizable Surface Mount Keypad Dome Switch For Hairfoil Device
Advantages
- Cost-Effective: Generally less expensive to produce than mechanical switches.
- Quiet Operation: They tend to be quieter than mechanical switches, which can be a
desirable feature in certain applications.
Disadvantages
- Limited Lifespan: While durable, they can wear out faster than mechanical switches
depending on usage.
- Less Precision: The tactile feedback may not be as pronounced as in mechanical
switches, which could affect user experience.
Key Features
Durability: They are designed to withstand a significant number of key
presses, making them suitable for high-use applications.
Compact Design: The low-profile design of dome switches allows for slim device
designs, making them ideal for portable electronics.
Tactile Feedback: Dome switches provide a noticeable tactile response when pressed,
which enhances user experience by confirming the input.
Dome Shape: The switch typically consists of a metal dome that collapses
under pressure, creating a short circuit to indicate activation.
Variety of Types: Dome switches can be found in various configurations, including
different actuation forces, sizes, and materials.
Applications
- Keyboards: Used in membrane keyboards for tactile feedback.
- Remote Controls: Common in TV remotes and other handheld devices.
- Appliances: Found in microwaves, ovens, and other home appliances.
- Industrial Equipment: Used in control panels and machinery interfaces.
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
Common Membrane switch structure
