Membrane Switch Assembly And Connection

- Jul 21, 2017 -

 membrane switch circuit is a circuit and conductor is printed on a thin film at the same time it is possible according to the requirements of computer array destined together is the key circuit which is a matrix connection method.Each column chart out a matrix method of connection of all switches have public attachment each line and at the same time also has a public connections that formed the combination of multiple independent form the key control circuit.Matrix connection method to qualify for at least its lead for key several times square root.Figure matrix arrangement method of the wiring diagram key number is fewer public bus connection method and matrix connection method between the difference is not obvious when key for many matrix connection method is obvious. The advantages of the bligh matrix connection method can not only meet the needs of computer decoding circuit and made by the child it lead the least convenient.Because the first thing to consider when printing the minimum width of wire.And row line is clear, of course, connecting the shorter, the less the better.Flexible membrane switch membrane switch and chassis assembly with a pressure sensitive rubber cover on the back of the so-called "adhesive" should choose membrane switch, touch panel bonding strength of rubber to ensure reliable paste it with machine.In order to ensure that in the process of the use of long time won't come unglued suggest chassis plate fixed membrane switch sheet metal or plastic board except to have enough rigidity is best can be recessed.The membrane switch assembly after the plane lower than the surrounding border.This can avoid the phenomenon of newborn.In addition on the lining membrane switch for the corresponding position should have qualified holes in order to pass the conduction band.
