Membrane switch is an operating system which integrates key function, indicating component and instrument panel. It consists of panel, upper circuit, isolation layer and lower circuit. If the membrane switch is pressed, the contact of the upper circuit is deformed downward and conducted to the electrode plate of the lower circuit. When the finger is removed, the contact of the upper circuit bounces back, the circuit is disconnected, and the circuit triggers a signal. The membrane switch has strict structure, beautiful appearance and good sealing performance. It also has the characteristics of moisture-proof and long service life. It is widely used in electronic communication, electronic measuring instruments, industrial control, medical equipment, automobile industry, intelligent toys, home appliances and other fields.
Membrane switch, also known as light touch keyboard, is a new type of electronic component composed of multi-layer plane. It is composed of key switch, panel, mark, symbol display and lining plate integrating light, machine and electricity. It is a fundamental change in the appearance structure of electronic products. It can replace the keys of conventional discrete components and more reliably implement the tasks of the operating system.
The membrane switch has the advantages of good water-proof, dust-proof, oil-proof, harmful gas erosion proof, stable and reliable performance, light weight, small volume, long service life, convenient assembly, washable panel without damage to characters, rich color, beautiful appearance, etc. The using of membrane switch can make your products more contemporary. The membrane switch panel, the main type of membrane switch, is a kind of electronic component which is composed of rigid or flexible printed circuit board as the base, with button or touch-feeling keys installed, and then covered with plastic (PC, PET, etc.) membrane panel printed with color decorative pattern, and integrates switching function and decorative function. It is a new type of man-machine interface. The connection between the switch circuit and the whole machine can be completed by welding or plug-in.
