Conductive Silver Ink Printing Membrane Touch Switch For WIFI Telecommunication

Product Specification

Conductive Silver Ink Printing Membrane Touch Switch For WIFI Telecommunication Device

Key Features

1. Construction:

   • Typically consists of multiple layers, including a top graphic layer, a spacer layer, and a bottom circuit layer.
   • The top layer is often printed with graphics or labels that indicate the function of each button.

2. Operation:

   • When a user presses the membrane, the top layer makes contact with the circuit layer beneath, completing an electrical circuit.
   • This action sends a signal to the device to perform a specific function.

3. Advantages:

   • Sealed Design: Offers protection against dust and moisture, making them suitable for harsh environments.
   • Low Profile: Can be designed to be very thin, allowing for sleek and compact device designs.
   • Customization: Can be easily customized in terms of shape, size, and graphical design.

4. Applications:

   • Commonly used in remote controls, appliances (like microwaves and washing machines), medical devices, and other electronic devices.

5. Response Time:

   • Generally, they offer fast response times, which is crucial for user experience.

Considerations

• Durability: While membrane switches can be durable, they may not withstand heavy mechanical impacts as well as mechanical switches.
• Tactile Feedback: Many users prefer tactile feedback, which is less pronounced in membrane switches compared to mechanical switches.

 
 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
