  1. Flat-Panel Membrane Keyboards Manufacturer

  2. Flat-panel membrane keyboards are most often found on appliances like microwave ovens or photocopiers. A common design consists of three layers. The top layer that is the one the user touches has the labels printed on its front and conductive stripes printed on the back.

  3. Under this it has a spacer layer, which holds the front and back layer apart so that they do not normally make electrical contact. The back layer has conductive stripes printed perpendicularly to those of the front layer. When placed together, the stripes form a grid.

  4. When the user pushes down at a particular position, their finger pushes the front layer down through the spacer layer to close a circuit at one of the intersections of the grid. This indicates to the computer or keyboard control processor that a particular button has been pressed.

  5. Generally, flat-panel membrane keyboards do not have much of a feel; so many machines which use them issue a beep or flash a light when the key is pressed. They are often used in harsh environments where water- or leak-proofing is desirable. Although used in the early days of the personal computers they have been replaced by the more improvised mechanical switch keyboards.

  6. Full-travel membrane-based keyboards are the most common computer keyboards today. They have one-piece plastic key top/switch plungers which press down on a membrane to actuate a contact in an electrical switch matrix.
