Using Membrane Keypad

In addition to normal protection against dust and moisture, the integrated acrylic inlay also protects the snap dome against possible deformation. Not even heavy point-specific pressure can damage the key areas. The electrical performance of these switches can also be varied depending on the specifications set for a particular device. The most common are that the loop resistance should be be less than 100 Ohms, while the open circuit resistance should be set at the minimum of 50 mega Ohms. The membrane switch should be able to function within the standards -20 °C to +75 °C as its operating temperature. The contact rating should stay within 100 Milli-amps at 28 VDC Maximum, while the contact bounce should be 5 milliseconds nominal. Modern membrane switches have also adapted to become water/moisture proof, heat/cold resistant and the front panels are designed so that they are easier to clean. Membrane keypads can have non-tactile, metal dome tactile and polydome tactile keys or buttons. And a combination of different tactile effects and forces can be combined in one membrane keypad product. The same is true for embossing where membrane keypads can combine pillow, rim or dome embossing with flat non-embossed keys.

The interacting layers are sealed together with adhesive to create a self-contained, low-voltage circuit in a tiny package. A membrane keypad can be combined with adjacent components and developed as a single operating unit. Electroluminescent lamps consist of foils with partially screen printed phosphor that glows when power is connected. For panels 1–3 mm in thickness, the technology can be used to highlight complex patterns that need to be visible in low light. For automatic adjustment between day and night lighting, photodiodes can be integrated directly into the membrane keypads. The special focus on materials means that a membrane keypads has a relatively long life with more than 10 million activations. When microorganisms encounter the surface of your user interface, their cell walls are penetrated by the protective agents within the membrane. Cell functions are interrupted, which prevents further growth and cell reproduction.

On a membrane keyboard, a keypress is registered through a thin membrane to circuit beneath it, while on a mechanical keyboard, a spring-loaded Mechanical key switch registers the keypress.
