Eight Embedded LEDs and Gold Plated Metal Dome Membrane

Eight Embedded LEDs and Gold Plated Metal Dome Membrane Switch

LED Membrane Switch Structure

1. Graphic Overlay - Polyester is usually the material of choice due to its superior chemical resistance and flex life compared to polycarbonate.we can either digitally print, screen-print, or employ a combination of both methods to ensure you get the right colors, textures and finishes your design requires.

2. Overlay Adhesive - This adhesive layer bonds the graphic overlay to the top circuit layer, and is typically an acrylic adhesive.

3.Top Circuit Layer - This is a 0.005" - 0.007" heat stabilized polyester printed with silver-filled electrically conductive inks and also dielectric inks.

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

5.Lower Circuit Layer - This is a 0.005" - 0.007" heat stabilized polyester printed with silver-filled electrically conductive inks and also dielectric inks. This layer terminates as a flexible tail that serves as the interconnect to controller PCBs or other electronics

6. Rear Adhesive Layer - This adhesive layer bonds the entire membrane switch package to the product enclosure, housing, or to a rigid support panel.

7. Rigid Support Layer - This optional layer can add structural integrity to the membrane switch assembly.
