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
