Best custom waterproof membrane switchProduct Description
What is Membrane Switch?
The membrane switch is a momentary switching device that is manufactured by using a series of flexible layers of polymer films and adhesives. The top layer, called a graphic overlay, is manufactured by printing on the down surface of transparent polyester or polycarbonate film. Membrane switches can be constructed of multiple circuit layers, and more optimized graphic design features, such as domed key embossing. Designs that are more complex require more material layers for proper construction and reliable operation. Membrane switches, when combined with components such as a tactile dome, graphic overlay, or integrated LEDs or resistors can provide the designer with virtually limitless capabilities to create the ideal custom user interface for their products.
Membrane switch is also called Membrane keypad, Membrane switch keypad,Tactile membrane switch keypad,LED membrane switch keypad,Copper foil membrane switch keypad,Colorful membrane switch keypad,Waterproof membrane switch keypad,Durable membrane switch keypad,metal dome membrane switch keypad,Embossed button membrane switch keypad,PET film membrane switch keypad, PC film membrane switch keypad,Anti scratch membrane switch keypad,Scratch resist membrane switch keypad, Anti UVultraviolet Ray radiationmembrane switch keypad...

The Structure and Working Principle of Membrane Switch.
1.Graphic Overlay – PET/PC is usually the material of choice due to its fantastic chemical resistance and flex property . UNIGREAT can do digital printing, screen-printing, or apply both methods to ensure you get the right colors, textures and finish your design requirements.
2.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.
3.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.
4.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.
5.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.
6.Rear Adhesive – This adhesive layer bonds the entire membrane switch to the product surface, housing, or to a rigid support panel. UNIGREAT can use the proper adhesive type and thickness to bond your membrane switch to your equipment.
