Metal Dome FPC Membrane Panels Switch  

CUSTOM CONTROLLER GRAPHIC OVERLAY MEMBRANE SWITCHES   In the production practice of membrane switches, the establishment principles and test methods of the electrical performance indicators such as withstand voltage and insulation resistance in membrane switch products and the numerical indicators (color tolerance) in the reproduction of the ink color (color, spot color) of the panel layer, etc. . Membrane switch is a control system integrating key function, indicating element and instrument panel.   Membrane switch is an operating system that integrates key functions, indicating elements and instrument panels. It consists of four parts: panel, upper circuit, isolation layer and lower circuit. When the membrane switch is pressed, the contacts of the upper circuit are deformed downward, and are in contact with the pole plate of the lower circuit. After the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the cir…
