Membrane switches belong to positive energy products, and their positive energy is not only reflected in their good quality and convenient use, but also in their own advantages that enable the switch to have better cyclic development. In other words, good switches are worth having good development, and good development of switches can also ensure better switches. Today, the editor will take you to understand the difference between flexible membrane switches and rigid membrane switches.
Flexible membrane switch is a typical form of membrane switch. This kind of membrane switch is called flexible because its facial mask layer, isolation layer and circuit layer are all composed of flexible films with different properties. The circuit layer of the flexible film switch uses polyester film (PET) with good electrical performance as the carrier of the switch circuit pattern. This layer is also divided into tactile spring pieces and upper and lower circuits. Due to the properties of polyester film, this film switch has good insulation, heat resistance, bending resistance, and high resilience. The graphics of the switch circuit, including the online connection of the switch and its lead wires, are printed with low resistance, low-temperature curing conductive coating. Therefore, the entire composition of the membrane switch has a certain degree of flexibility, which is not only suitable for use on flat surfaces, but also can be matched with curved surfaces. The flexible membrane switch lead wire is integrated with the switch body itself. When making the group switch online, it is gathered at a certain point of the membrane and extended outward according to the designated position and standard wire spacing in the design. It is connected to the rear circuit of the whole machine as a flexible, bendable, and sealed lead wire.
Hard membrane switch
The characteristics of hard film switches are convenient material selection, stable process, low resistance, and the ability to directly solder certain components in the circuit on their back. In the case of a small area, the hard lining layer can be omitted. Hard film switches generally use metal conductors as conducting labyrinth contacts, so they have a better tactile feel. The disadvantage is that it is not as convenient to install in the whole machine as flexible film switches, often requiring welding and leading out the leads through flat cables. The information feedback of hard film switches can generally use metal tactile spring pieces in addition to buzzing signals and LED indications.
