PET Embossed Button Tactile Front Panel Membrane Overlay Electronic Keyboard With Flexible Circuit
Membrane switch is an electrical switch for turning a circuit on and off. It differs from a mechanical switch, which is usually made of copper and plastic parts: a membrane switch is a circuit printed on PET or ITO. The ink used for screen printing is usually copper / silver / graphite filled and therefore conductive.
1.Graphic Overlay – PET/PC is usually the material of choice due to its superior chemical resistance and flex life . MEIBORUI 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. The material is same as the fourth layer. Only the thickness will be different according to the physical truth. 3.Top Circuit Layer – The material of this layer is special. This is a 0.1mm heat stabilized PET printed with silver-filled electrically conductive inks and also dielectric inks, which used for fastening metal domes. 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 layer is a 0.1mm--0.25mm 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. MEIBORUI can specify the appropriate adhesive type and thickness to bond your membrane keypad to your equipment.
