Flexible membrane switch is a typical form of membrane switch. The reason why this type of membrane switch is called flexible is that the mask layer, isolation layer, and circuit layer of the membrane switch are all composed of various flexible films with different properties. The circuit layer of the flexible membrane switch uses polyester film (PET) with good electrical properties as the carrier of the switch circuit pattern. This layer is also divided into hand-feeling shrapnel and upper and lower circuits. Due to the influence of the properties of the polyester film, the membrane switch has good insulation, heat resistance, bending resistance and high resilience. The graphics of the switch circuit, including the connection of the switch and its lead-out wires, are all printed with low-resistance conductive paint cured under low-temperature conditions. Therefore, the composition of the entire membrane switch has a certain degree of flexibility, which is not only suitable for use on a flat body, but also fits with a curved body. The lead wire of the flexible membrane switch is integrated with the switch body itself. When making the connection of the group switch, it is gathered at a certain place on the membrane, and extends outward according to the position specified by the design and the standard line distance, as a soft membrane switch. , Arbitrarily bendable and sealed lead wires are connected to the rear circuit of the whole machine.
