OEM Customized Design Diy Membrane Switch With Glossy Surface

Materials Needed

1. Conductive Material: Aluminum foil or conductive tape.
2. Insulating Material: Cardstock or a similar non-conductive material to create spacers.
3. Adhesive: Glue or double-sided tape.
4. Design Software: Optional, for creating the layout of your keypad.
5. Laminator: Optional, for added durability.

Steps to Create a Membrane Switch

1. Design Your Keypad:

   • Decide on the layout and number of buttons. A common approach is to use a matrix layout (e.g., 3x3) which reduces the number of wires needed [1].

2. Create the Layers:

   • You will need four layers:
     • Front Decal: This is the top layer that users will see and press.
     • Top Foil Layer: This layer contains the conductive paths for the rows.
     • Bottom Foil Layer: This layer contains the conductive paths for the columns.
     • Cutout Layer: This layer separates the top and bottom foil layers until a button is pressed [3].

3. Assemble the Layers:

   • Print your designs for the front decal and the foil layers. Use copper tape for the conductive paths on the top and bottom layers.
   • Cut holes in the cutout layer where you want the buttons to be. This allows the top and bottom layers to connect when pressed [3].

4. Connect the Layers:

   • Glue the layers together, ensuring that the cutout layer is positioned correctly to allow contact between the top and bottom foil layers when a button is pressed [3].

5. Final Touches:

   • Optionally, laminate the front decal for protection against wear and tear. This can help prolong the life of your membrane switch [1].

Considerations

• Durability: Using a laminator can enhance the durability of your keypad, especially if it will be used frequently [1].
• Tactile Feedback: If you want tactile feedback, consider incorporating metal dome switches beneath the top layer [3].
• Testing: Once assembled, connect your membrane switch to a microcontroller (like an Arduino) to test its functionality [3].

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

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
