Flexible Three Button Custom Membrane Switch Panel With Four
Contacts Connector
Key Features of Custom Membrane Switch Panels
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.
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.
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.
Backlighting Options:
- Various backlighting technologies can be employed, including LEDs
and light guide films, to enhance visibility and user experience.
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
