Come to us at the start of your project, and our experienced -based engineers will work alongside you to design customized membrane switches to the exact specifications of your applications. We design and manufacture all of our membrane switches in the CHINA for optimal quality and timely service.


Our engineers have the experience and know-how to handle even the biggest challenges – such as fitting all necessary switch features for optimal functionality in the space-constrained layouts of complex circuit designs.

A full range of other in-house services, including color matching and digital printing, enables you to conform to your customers' brand standards and provide the aesthetics to create the perfect, intuitive user interface.

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.
