Haiwen Membrane Switch Limited                                                                    Product description

•      Metal domes added to the membrane switch provide the upper circuit layer. That contributes the keys to visual, audible, and tactile feedback. The switch can performance well in high temperature environment. The product are mainly used as control keypad for movable electric appliances. Also, keypad of Haiwen can be customized based on customer’s design such as button icons, colors etc. Transparent window is manufactured with UV ink. Selecting Autotype F150 matte PET to screen print the overlay appears elegant and colorful. The circuits are made of Acheson 478ss silver paste, so that it can be low resistance and function well. The rear adhesive is 3M 9448HK.

      

   Substrate 

   

• For the production of membrane switch panel substrate of the following: 

• (1) polycarbonate filmPolycarbonate film great temperature range (-135 ~ 135 ℃), when the temperature or humidity changes, the performance of this material changed little, from 100 to ensure the panel can be various types of equipment under a variety of harsh environment use.(2) PVC filmPoor heat resistance, especially in high temperature conditions, the softening temperature of 59 ℃, less flexible polycarbonate film good. But it has a high elongation (130%), but also because of its low price, it is suitable for use in the general conditions.(3) polyester filmFlexibility and heat resistance are good, the price range of between polycarbonate film and PVC film. But its hard to process into films matt type surface texture, often isolated and the transparent sheet, while the vast majority of the surface of polyester film of plastic printing ink can not get satisfactory results, generally requires the use of a particular special ink.
