Membrane panel switch panel 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 panel switch is pressed, the contacts of the upper circuit are deformed downward, and are in contact with the pole plates of the lower circuit. After the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the circuit triggers a signal.
1. The connecting wires of the membrane panel switch should be well protected and should not be placed downward.
2. For products with viewing windows, prevent the material from bending under force, otherwise creases may be left.
3. Membrane panel switches should be stored in a room at room temperature, and should be treated with dust and moisture protection. There is no acid, alkali or other corrosive gases in the surrounding air.
4. The front and back sides of the product are generally covered with a transparent membrane to protect the product surface or display window from being scratched, and the protective membrane should be retained.
5. The foam cotton in the product packaging is separated by foam cotton to reduce the damage to the keys caused by external unconscious force.
6. After taking out a few of them from the original packaging, they should be bundled as they are, but they must not be bundled too tightly.
7. Products with a feel (metal shrapnel, hot-pressed convex buds) need to be boxed and placed vertically to prevent the feeling of failure due to long-term heavy pressing of the keys.
Three characteristics of membrane panel switch
1. Durability: The membrane panel switch can be used for a very long time, and the number of times it can be used can reach millions of times. The reason for the long life is that the action of the switch is very simple. Because the membrane panel switch has a relatively simple structure. The whole is also sealed. It is not easy to cause damage at will. The main work is to control the switch, the usage rate is not very frequent, and it is not easy to wear, so the usable time is very long.
2. Good sealing performance: Because the membrane panel switch is an integrally sealed part, the contacts of the switch are not disturbed by the external environment, so there is no need to worry about corrosion, and it is not easy to produce oxidation; at the same time, it can also prevent dust. pollution, can be used in a variety of harsh environments.
3. The volume is relatively small and the quality is relatively light: the volume of the membrane panel switch is generally very small, but there are many buttons on it, so this requires the rationality of the design of the membrane panel switch. Excellent features ensure that the membrane panel switch is both beautiful and practical.
How much is the customized production price of membrane panel switch
Membrane panel switch is a design type product. Although it is customized according to the customer's production equipment requirements, several aspects are required for customized production. The important thing is its detailed information.
The first is the size, the size must be known, this is to facilitate the quotation to estimate the value of the membrane material, and then the color, structure, thickness, line order and material material, etc. If the customer has special requirements for outstanding performance, it will also combine the information given by the customer. , give advice on which materials can meet these requirements, etc.
What material is better for membrane panel switch?
The main structure of the membrane panel switch panel is generally composed of buttons and membranes. The thickness of the membrane panel switch is generally controlled at about 0.15mm. If it is too thin, there will be no resilience, and the use of the switch will not be so sensitive. Also, if the queen mother is the queen, it will be very laborious to press, and they are all bad products.
When making flat switches, when choosing a membrane, they tend to choose a slightly thicker membrane to ensure the long-term use of the product. Another application in the circuit contact type panel requires the use of a slightly thinner membrane. Only when the diameter of the bubble is compared, the thinner membrane is selected.
The design of the overall structure of the membrane button is very simple. When you get a membrane panel, you only need to take off the button cover and see the circuit and circuit board of the panel.
When the shape of the designed button is relatively large, it is best to choose a membrane with a thickness of 0.18 mm. This thickness of the membrane has a moderate thickness and has a good rebound effect. It can be used frequently and is not easy to be damaged. If the selected membrane thickness is not enough, it is easy to penetrate. Make the membrane panel switch insensitive to use.
The button of the membrane panel switch panel has many advantages. Its working principle has outstanding advantages compared with other different types of buttons. It welds many conductive metal points on a conductive membrane, and each button can be connected to the same membrane. How does the button of the membrane panel of the panel switch work? It can achieve different control effects. The membrane panel has a barrier layer. Its function is to make a button and the panel react when no one presses it. through the circuit. Complete instructions.
Everyone should be familiar with membrane panel switches, and they are widely used in our lives. The mask materials of membrane panel switches are generally only polyester materials, mainly polyvinyl chloride (PVC), polycarbonate (PC) , Polyester (PET) three kinds, three kinds of materials are good and bad, you can choose according to your own needs.
Such as: bending life, chemical erosion resistance, abrasion resistance, insulation performance, window transparency, drum clarity, temperature level, and UV resistance are used as reference data for selection.
There is a lack of the same standard for how to distinguish between plastic membrane and membrane. According to the difference in thickness, it is divided into membrane, sheet and plate. According to the definition of the German DIN55405 standard, those whose thickness is less than 1.5mm are called membranes, and those whose thickness exceeds 1.5mm are called sheets. In my country, those with a thickness of 0.3 mm or less are called membranes, those with a thickness of 0.3-0.7 are called sheets, and those with a thickness of 0.8 mm or more are called sheets.
