Product Name: PET/PVC/PC small switch panel

1. Overlay Adhesive – This adhesive layer stick the graphic overlay to the top circuit layer, and is usually an acrylic adhesive. The material is same with the fourth layer. Only the thickness maybe different according to the actual situation.
2. Top Circuit Layer – The material of this layer is specific. Is is a 0.1mm thickness thermostable PET film printed with conductive silver ink and also dielectric oil, which used for fastening metal domes.

This panel is our sample picture. If you need to custom the panel you designed, please provide the following information

1. Required files: CAD, CDR, AI, Corel Draw, etc. (preferably CDR and AI, with color)

2. Size: Size of panel and cable

3. Color: Pantone color card

4. Buttons: number, emboss or not, metal dome or not

5. LED: number, color, type

6. Window: clear window or transparent window

7. Surface treatment: glassy or matte

8. Connector type: flat cable (Please specify the type you need)

More details are as below,

1. Circuit Spacer – This layer separates the top circuit from the bottom circuit so that switch remains normally break until the keypad is pressed. The circuit spacer is a polyester spacer with adhesive on both sides.

2. Lower Circuit Layer – This layer is a 0.1mm--0.25mm thickness thermostable PET film printed with conductive silver ink and also dielectric oil. This layer terminates as a flexible tail that serves as an interconnector to controller PCBs or other IC.
