  Membrane keyboard - Biocrawler
A membrane keyboard is a computer keyboard whose "keys" are not separate, moving parts, as with the majority of other keyboards, but rather have only outlines and symbols printed on a flat, flexible surface.
Membrane keyboards, which work by electrical contact between the keyboard surface and the underlying circuits when keytop areas are pressed, were used with some early 1980s home computers, and have been much used in consumer electronics devices.
Smaller, specialised membrane keyboards, typically numeric-and-a-few-control-keys only, have been used in access control systems (for buildings and restricted areas), simple handheld calculators, domestic remote control keypads, and other similar devices where the amount of typing is relatively small or infrequent.

 Membrane keyboard apparatus having common apertured electrode, aperture inserted electrodes and conductive bubble ...
Membrane keyboard apparatus is disclosed as including an insulator having a conductive sheet thereon providing a plurality of first electrode members and a plurality of second electrode members to form an array of individual switching units.
Such keyboard apparatus should also include a membrane member having height differential obtaining means for electrically insulating at least one electrode member of the electrode members of an individual switching unit such that further insulator means between the membrane and electrode members of the individual switching unit are not required.
The membrane keyboard so made will include a visual indication of switch location, as from the height differential obtaining means, can provide a differential threshold of switching which would require the stacking of spacers in known prior switches, and includes a minimum of parts, and clearly fewer parts than in known prior switches.

A membrane keyboard is one where the keys are not separate, moving parts.
Membrane keyboards function by electrical contact between the keyboard surface and the underlying circuits when key areas are pressed.
Two major benefits of membrane keyboards are that they are very inexpensive to mass produce, and are more resistant against dirt and liquids than most other keyboards.

  Mechanical vs. Membrane vs. Scissor-Switch Membrane Keyswitches on Keyboards by ErgoCanada.com
Membrane keyboards are typically inexpensive and can range from firm to soft feel depending on the design of the rubber dome, however most have a 'softer' feel due to the 'sponginess' of the dome.
In contrast, a membrane keyboard must be manufactured and assembled in a clean-room environment, so that it is not generally effective to try to clean or repair such a keyboard.
With most membrane keyboards, there is no tactility as the key must be pressed all the way down, and few people can control accurately the amount of force and distance needed when the only indication of this is when you 'bottom out' at the end of your keystroke.

 Embedded Systems Design - Embedded.com
When a user presses a simulated key, the top membrane is pushed through the spacer hole and makes contact with the bottom membrane, completing the circuit.
Membrane keyboards, which are much hardier than normal key switch keyboards, offer the advantage of complete customization by programming the cell matrix for any application.
As a result, they are not as hazard proof, but the economical membrane construction enables the keyboard to retail at lower cost.

 membrane keyboard - Membrane Keyboard Information
A membrane keyboard is a computer keyboard device which "keys" are not separate, moving parts, as with the majority of other keyboards, but rather have only outlines and symbols printed on a flat, flexible surface.
Moden membrane switch keyboards, which function by complete electrical contact between the keyboard upper - lower surface and the underlying circuits when keytop areas are pressed, were used with some early 1980s computers, and still use in large numbers of consumer electronics devices.
The keyboards are very inexpensive to mass produce, and are more durable against dirt,dust and liquids than most other keyboards, but due to the low or non-existent amount of tactile feedback provided, most people have difficulty typing with them, especially when large numbers of characters need to be typed.

Membrane switch is rapidly outdating the present type of the electronic switches i.e.
The keyboard consists of a top and bottom layer of polyester with a tactile actuator that when pressed, momentarily complete the circuit while providing the user a degree of response based on the keyboard construction.
The difference between Tactile and Non-tactile membrane keyboard is that Non-tactile rely on a sensory touch than tactile touch, such as audio or visual stimuli that alerts the user to switch the keyboard off.
