A, membrane switch introduction
1, membrane switch membrane switch, also known as the light-touch keyboard, the use of flat multi-layer combination of the overall sealing structure, is the key switches, panels, markers. Symbol display and liner sealed in a set of optical, mechanical and electrical integration of a new type of electronic components, is a fundamental change in the appearance of the structure of electronic products, which can replace the conventional discrete components of the keys, more reliable implementation of the operating system's tasks.
Two, membrane switch advantages
1, membrane switch has a good waterproof, dustproof, oil-proof, anti-hazardous gas erosion, stable and reliable performance, light weight, small size, long life, easy to install and connect, the panel can be washed and the characters are not damaged, colorful, beautiful and generous advantages. The use of membrane switches make your products more contemporary.
2, the main types of membrane switch membrane switch panel is a rigid or flexible printed circuit board as a substrate, the installation of tactile or non-tactile keys, and then coated with colorful decorative patterns printed on plastic (polycarbonate PC, polyester PET, etc.) film panels constitute.
3. It is a new type of man-machine dialog interface which integrates switch function and decorative function into one electronic part. The connection between its switch circuit and the whole machine can be completed by welding or plugging.
Three, membrane switch use:
1, computer: operating keyboard, monitor, printer, plotter;
2, home appliances: remote control, electronic locks, washing machines, microwave ovens, rice cookers, audio and video equipment, etc.;
3, office systems: telephone, fax machine, Copier, counter;
4, electronic toys: electronic piano, game machine, electronic target;
5, instrumentation: measuring instruments, analytical instruments, marine instruments, medical instruments;
6, electromechanical products: numerical control machine tools, electronic scales, robots, printing machinery.
7, Membrane switches have been widely used in electronic communications, electronic measurement of instruments, industrial control, medical equipment, automotive industry, smart toys, household appliances and other fields.
Four, membrane switch use precautions
First of all, membrane switch and membrane switch lined with bubble film is for the key to reduce pressure to prevent failure, should be retained.
2. Membrane switch display window on the front and back of the cover of the transparent film is to protect the membrane switch, do not easily tear off.
3. Remove a few of the membrane switch, should be in accordance with the original bundle, but should not be bundled too tight.
4. There is a sense of touch, the number of large film surface stickers, membrane switches, need to be boxed vertical, to prevent the key long time heavy pressure failure.
5. Membrane switches out of the line to be protected, not out of the line placed downwards.
6. Membrane switch with a display window, in the take, put to prevent the material bending force, will leave a crease.
7. Membrane switches are stored in a room at room temperature, should be dust-proof, moisture-proof treatment, no acidic, alkaline or other corrosive gases in the surrounding air.
Five, membrane switch structure use
1, the panel layer is generally lower than 0.25MM PET, PC and other colorless translucent sheet screen printing on the beautiful patterns and text made, because the panel layer of the most important role is to play a role in the marking and keying, so the selected material must have high transparency, high ink adhesion, High elasticity, high toughness and other characteristics.
2, the face of the glue is the main role of the panel layer and the circuit layer is closely linked to achieve the effect of sealing and connecting, this layer is generally required to be between 0.05 - - 0.15MM thickness, with a high degree of adhesion and anti-aging; in the production, the general selection of special membrane switch double-sided adhesive, some membrane switch requires waterproof high temperature, so the face of the glue must be used according to the needs of the Different nature of the material.
We now know what is the membrane switch it, membrane switch has many uses, it seems that we are indispensable. There is also everyone should pay attention to the membrane switch notes, the following editorial also said, in the future there is what do not know the decoration aspects of things, you can come to attention to us.
