Custom LED Membrane Switch With Waterproof Function

Custom LED Membrane Switch With Waterproof Function  A membrane switch is a printed electronic circuit that uses pressure to open and close a circuit. The membrane switch circuitry is most often screen printed using conductive inks, which are typically made of silver, carbon, and/or graphite.Membrane switches are part of a range of devices considered to be user interfaces (also called operator interfaces, or man-machine interfaces) along with display-based touch screens, and mechanical switches such as push-button, toggle, rocker, and slide switches. The ultimate purpose of a membrane switch is to serve as the interface between man and machine, enabling an operator to communicate with a piece of equipment, instrument, or machinery.

Production Process

1.Graphic Overlay – PET/PC is usually the material of choice due to its fantastic chemical resistance and flex property . ZDX can do digital printing, screen-printing 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. . 6.Rear Adhesive – This adhesive layer bonds the entire membrane switch to the product surface, housing
