Non-Tactile Membrane Keyboard

Non-tactile membrane keyboards are similar to a tactile switch, but when pressed, there is no tangible feedback response. Instead, Non-tactile membrane keyboards require another way to alert the user that the switch has been activated. Typically, they rely on an audible or visual response from the unit.

Non-tactile membrane keyboards are a type of electronic switch that uses a thin, flexible membrane to make contact with a circuit board. These switches are constructed from multiple layers of flexible materials, including polyester, polycarbonate, and adhesive layers. The top layer of the switch is a graphic overlay that provides labeling and design elements for the switch. The middle layer is the circuit layer, which contains conductive traces that make contact with the switch's contacts. The bottom layer is the adhesive layer that attaches the switch to the device.

When a non-tactile membrane keyboard is pressed, the graphic overlay layer makes contact with the circuit layer, which triggers the switch's action. The switch's contacts are designed to provide a closed circuit when the switch is pressed, which triggers the device to perform a specific function. Non-tactile membrane keyboards do not provide tactile feedback, meaning that they do not have the same "click" sensation as mechanical switches.
