Flexible Three Button Custom Membrane Switch Panel With Four Contacts Connector

Flexible Three Button Custom Membrane Switch Panel With Four Contacts Connector

Key Features of Custom Membrane Switch Panels

1. Material Options:

   • Graphic Overlays: Typically made from polyester or polycarbonate, these overlays can be customized for durability and aesthetic appeal.
   • Circuitry: Options include printed silver circuits or etched copper flex circuits, with copper flex being preferred for its durability and flexibility in demanding environments.

2. Design Flexibility:

   • Custom designs can incorporate various features such as tactile feedback (using metal domes), backlighting (LEDs, electroluminescence), and embossing for enhanced usability.
   • The ability to integrate touchscreens and other electronic components allows for complex user interfaces.

3. Environmental Resistance:

   • Membrane switches can be designed to withstand harsh conditions, including moisture, chemicals, and extreme temperatures, making them suitable for outdoor and industrial applications.

4. Backlighting Options:

   • Various backlighting technologies can be employed, including LEDs and light guide films, to enhance visibility and user experience.

5. Sealing and Shielding:

   • Custom membrane switches can be environmentally sealed to prevent moisture ingress and can include shielding to protect against electromagnetic interference (EMI) and electrostatic discharge (ESD).

Applications

Custom membrane switch panels are widely used in:

• Medical devices
• Consumer electronics
• Military equipment
• Industrial machinery

 
 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
