When designing custom membrane switch panel, here are some ideas to consider:

• The desired quantity

• The type of connector required

• The number of keys and their purpose

• The addition of LEDs or another lighting source

• The need for visual feedback

• The graphic elements to include

• The style of your graphic overlay

Notice: We have the capacity to provide you membrane switches with other special requirements, such as water proof, shielding, windows/lens coating, embedded LEDs, UV glossy/ matte/ textured, etc.

Opinions about membrane switch prototype

To get started on manufacturing your prototype, all you need to do is send us your drawings, and our engineers and experts will check them. For mechanical drawings, it is best to use .DWG and .ai formats. For illustrations, send us a vector file (if you don't have one on hand, don't worry – we also offer vector image creation services).

No matter whether they're preliminary or complete, your drawings will serve as a jump-off point for our designers and manufacturing team. We will get back to you with a quote in record time.

Opinions of Custom your membrane switch prototype and design

1. Backlighting: To add another dimension to your membrane switch with LEDs or fiber optics.
   

2. Electroluminescent panel: The gold standard in lighting is perfect distribution.

3. Support plates: Integrate a rigid plate behind your keyboard by using aluminum, polycarbonate, or acrylic.

4. Flexible circuits: The flexibility of printed circuits means they could be installed onto a curved surface.

5. Graphic overlay surface finishes: glossy, anti-reflective, textured, mirror effect, metallic effect, faux stainless steel…

6. Design materials: For interior or exterior application, or antimicrobial materials needed?

7. Manufacturing options:  colours, raised embossed keys, thermochromic or photochromic inks, etc.

8. Connector options:  male connector, female connector, soldered, or ZIF connection

9. Circuit protection: We provide ESD, EMI, and RFI protection.
