Membrane switch, thin film control panel with FPC connector
The difference between the FPC membrane switch and the conventional membrane switch is that the circuit is no longer a silver printed circuit, but a more stable FPC circuit material, which is more resistant to high temperatures and corrosion. The FPC membrane switch circuit layer uses FPC flexible circuit board. The circuit has high precision, output pitch of 1.0mm, features of low resistance value, stable and reliable performance and long service life.
This type of membrane switch is referred to as a flexible membrane because the mask layer, barrier layer and circuit layer of the membrane switch are composed of soft films of various properties. The circuit layers of the flexible membrane switch are made of polyester film (PET) with good electrical properties as a carrier for the switching circuit pattern. This layer is also divided into hand-featured shrapnel and up and down circuits.
Due to the characteristics of the polyester film, the FPC membrane switch provides good insulation, heat resistance, folding resistance and high resilience of the membrane switch. The circuit of the switching circuit, including the switch connection and its lead-out line, is printed with a low-resistance conductive coating and cured under low temperature conditions.
