Silk-printing Dustproof Tactile Dome Switch Poly With 3M9448

 

 

 

 

A membrane switch consists of various layers laminated together. The layers of a basic membrane switch construction include: a membrane overlay, spacer, printer circuit, rear adhesive, and tail filler. Depending on the environment and requirements of the application into which the membrane switch plugs into, the construction can vary. For example, if shielding is necessary, a two-circuit membrane switch design would be a better construction choice.

 

 

Material 

1.Polyester: is used for both circuit layers and overlay layers. High temp and corrosion resistant, the flexibility and mechanism are good as well as high reliability. It is mostly suitable used in products where the application environment are atrocious or products are emboss required.

2.Polycarbonate:is usually used for overlays. It has more competitive price than PET so mostly used in products that styles improved frequently, such as microwave oven and toys , etc
