OEM Customized Design Membrane Switch Design Industrial With Glossy
Surface
1.Production Considerations
- Cost-Effectiveness: Optimize the design for manufacturability and cost.
- Scalability: Ensure that the design can be easily scaled for larger production
runs.
2.Layer Structure
- Overlay: The top layer, usually printed with graphics and text, is made of
a durable material like polyester or polycarbonate.
- Spacer: This layer creates a gap between the overlay and the circuit
layer, allowing for the switch to function.
- Circuit Layer: Typically made of a flexible printed circuit (FPC), this layer
contains the conductive traces that complete the circuit when
pressed.
3.Durability
- Material Selection: Choose materials that resist abrasion, chemicals, and moisture.
- Environmental Considerations: Design for the intended environment, whether it’s outdoor use,
exposure to liquids, or extreme temperatures.
4.Graphic Design
- Clarity: Ensure that icons and labels are easily readable. Use
high-contrast colors.
- Branding: Incorporate brand colors and logos for consistency.
- User Experience: Design with user interaction in mind. Consider button sizes and
spacing for ease of use.
5.Switch Technology
- Tactile Feedback: Incorporate features that provide tactile or audible feedback
when a button is pressed.
- Non-tactile Options: Consider capacitive touch technology for a sleek, modern look
without moving parts.
6.Adhesive and Mounting
- Adhesive Type: Select the appropriate adhesive for the surface it will be
mounted on, ensuring it provides a strong, lasting bond.
- Mounting Options: Consider how the switch will be mounted—directly on a panel,
embedded in a device, etc.
7.Regulatory Compliance
- Ensure that the design complies with relevant industry standards,
especially for medical devices or consumer electronics.
8.Testing and Prototyping
- Prototyping: Create prototypes to test the design for usability and
durability.
- User Testing: Conduct tests with real users to gather feedback on the design
and functionality.
Membrane Switch 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
Polycarbonate
1.Wide range of surface finishes and thicknesses
2.More cost-effective 3.For internal and external use
2) Embossing--rim embossing pillow embossing dim embpssing
Graphic overlays can be embossed in order to insert domes
(tactile), leave space for mechanical keys and provide tactile
indications Pedestal embossing
3)Windows ----for display function
1. print colors windows
2.transparent finishes windows
4)Keys/buttons
Tactile keys---with metal dome or poly dome
Non-tactile--silver printing spot
5) Embeded LEDs-
miniature LED, LED colors:white, yellow, orange, green, red, etc.
6)Cable
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 or acrylic
